GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

How to install wiringPi
|
||||
=======================
|
||||
|
||||
The easiest way is to use the supplied 'build' script:
|
||||
|
||||
./build
|
||||
|
||||
that should do a complete install or upgrade of wiringPi for you.
|
||||
|
||||
That will install a dynamic library.
|
||||
|
||||
Some distributions do not have /usr/local/lib in the default LD_LIBRARY_PATH. To
|
||||
fix this, you need to edit /etc/ld.so.conf and add in a single line:
|
||||
|
||||
/usr/local/lib
|
||||
|
||||
then run the ldconfig command.
|
||||
|
||||
sudo ldconfig
|
||||
|
||||
If you want to install a static library, you may need to do this manually:
|
||||
|
||||
cd wiringPi
|
||||
make static
|
||||
sudo make install-static
|
||||
|
||||
|
||||
To un-install wiringPi:
|
||||
|
||||
./build uninstall

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

wiringPi Examples
|

=================
|
||||
|
||||
There are now too many examples to compile them all in a sensible time,
|
||||
and you probably don't want to compile or run them all anyway, so they
|
||||

|
||||
|
||||
To compile an individual example, just type
|
||||
|
||||
make exampleName
|
||||
|
||||
To really compile everything:
|
||||
|
||||
make really-all
|
||||
|
||||
The individual tests are:

*
|

* IMPORTANT: To run this test we connect 2 GPIO pins together, but

* before we do that YOU must make sure that they are both setup
|

* the right way. If they are set to outputs and one is high and one low,
|
||||
* then you connect the wire, you'll create a short and that won't be good.
|
||||
*
|
||||
* Before making the connection, type:
|
||||
* gpio mode 0 output
|
||||
* gpio write 0 0
|
||||
* gpio mode 1 input
|
||||
* then you can connect them together.
|
||||
*
|
||||
* Run the program, then:
|
||||
* gpio write 0 1
|
||||
* gpio write 0 0
|
||||
*
|
||||
* at which point it will trigger an interrupt and the program will
|
||||
* then do the up/down toggling for itself and run at full speed, and
|
||||
* it will report the number of interrupts recieved every second.

* Use the SoC's pull-up and pull down resistors that are avalable
|
||||
* on input pins. So compile & run this program (via sudo), then
|
||||
* in another terminal:
|
||||
* gpio mode 0 up
|
||||
* gpio mode 0 down
|
||||
* at which point it should trigger an interrupt. Toggle the pin
|
||||
* up/down to generate more interrupts to test.

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates
|
||||
the terms and conditions of version 3 of the GNU General Public
|
||||
License, supplemented by the additional permissions listed below.
|
||||
|
||||
0. Additional Definitions.
|
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser
|
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
||||
General Public License.
|
||||
|
||||
"The Library" refers to a covered work governed by this License,
|
||||
other than an Application or a Combined Work as defined below.
|
||||
|
||||
An "Application" is any work that makes use of an interface provided
|
||||
by the Library, but which is not otherwise based on the Library.
|
||||
Defining a subclass of a class defined by the Library is deemed a mode
|
||||
of using an interface provided by the Library.
|
||||
|
||||
A "Combined Work" is a work produced by combining or linking an
|
||||
Application with the Library. The particular version of the Library
|
||||
with which the Combined Work was made is also called the "Linked
|
||||
Version".
|
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the
|
||||
Corresponding Source for the Combined Work, excluding any source code
|
||||
for portions of the Combined Work that, considered in isolation, are
|
||||
based on the Application, and not on the Linked Version.
|
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the
|
||||
object code and/or source code for the Application, including any data
|
||||
and utility programs needed for reproducing the Combined Work from the
|
||||
Application, but excluding the System Libraries of the Combined Work.
|
||||
|
||||
1. Exception to Section 3 of the GNU GPL.
|
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License
|
||||
without being bound by section 3 of the GNU GPL.
|
||||
|
||||
2. Conveying Modified Versions.
|
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a
|
||||
facility refers to a function or data to be supplied by an Application
|
||||
that uses the facility (other than as an argument passed when the
|
||||
facility is invoked), then you may convey a copy of the modified
|
||||
version:
|
||||
|
||||
a) under this License, provided that you make a good faith effort to
|
||||
ensure that, in the event an Application does not supply the
|
||||
function or data, the facility still operates, and performs
|
||||
whatever part of its purpose remains meaningful, or
|
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of
|
||||
this License applicable to that copy.
|
||||
|
||||
3. Object Code Incorporating Material from Library Header Files.
|
||||
|
||||
The object code form of an Application may incorporate material from
|
||||
a header file that is part of the Library. You may convey such object
|
||||
code under terms of your choice, provided that, if the incorporated
|
||||
material is not limited to numerical parameters, data structure
|
||||
layouts and accessors, or small macros, inline functions and templates
|
||||
(ten or fewer lines in length), you do both of the following:
|
||||
|
||||
a) Give prominent notice with each copy of the object code that the
|
||||
Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
4. Combined Works.
|
||||
|
||||
You may convey a Combined Work under terms of your choice that,
|
||||
taken together, effectively do not restrict modification of the
|
||||
portions of the Library contained in the Combined Work and reverse
|
||||
engineering for debugging such modifications, if you also do each of
|
||||
the following:
|
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that
|
||||
the Library is used in it and that the Library and its use are
|
||||
covered by this License.
|
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
||||
document.
|
||||
|
||||
c) For a Combined Work that displays copyright notices during
|
||||
execution, include the copyright notice for the Library among
|
||||
these notices, as well as a reference directing the user to the
|
||||
copies of the GNU GPL and this license document.
|
||||
|
||||
d) Do one of the following:
|
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this
|
||||
License, and the Corresponding Application Code in a form
|
||||
suitable for, and under terms that permit, the user to
|
||||
recombine or relink the Application with a modified version of
|
||||
the Linked Version to produce a modified Combined Work, in the
|
||||
manner specified by section 6 of the GNU GPL for conveying
|
||||
Corresponding Source.
|
||||
|
||||
1) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (a) uses at run time
|
||||
a copy of the Library already present on the user's computer
|
||||
system, and (b) will operate properly with a modified version
|
||||
of the Library that is interface-compatible with the Linked
|
||||
Version.
|
||||
|
||||
e) Provide Installation Information, but only if you would otherwise
|
||||
be required to provide such information under section 6 of the
|
||||
GNU GPL, and only to the extent that such information is
|
||||
necessary to install and execute a modified version of the
|
||||
Combined Work produced by recombining or relinking the
|
||||
Application with a modified version of the Linked Version. (If
|
||||
you use option 4d0, the Installation Information must accompany
|
||||
the Minimal Corresponding Source and Corresponding Application
|
||||
Code. If you use option 4d1, you must provide the Installation
|
||||
Information in the manner specified by section 6 of the GNU GPL
|
||||
for conveying Corresponding Source.)
|
||||
|
||||
5. Combined Libraries.
|
||||
|
||||
You may place library facilities that are a work based on the
|
||||
Library side by side in a single library together with other library
|
||||
facilities that are not Applications and are not covered by this
|
||||
License, and convey such a combined library under terms of your
|
||||
choice, if you do both of the following:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work based
|
||||
on the Library, uncombined with any other library facilities,
|
||||
conveyed under the terms of this License.
|
||||
|
||||
b) Give prominent notice with the combined library that part of it
|
||||
is a work based on the Library, and explaining where to find the
|
||||
accompanying uncombined form of the same work.
|
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Lesser General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Library as you received it specifies that a certain numbered version
|
||||
of the GNU Lesser General Public License "or any later version"
|
||||
applies to it, you have the option of following the terms and
|
||||
conditions either of that published version or of any later version
|
||||
published by the Free Software Foundation. If the Library as you
|
||||
received it does not specify a version number of the GNU Lesser
|
||||
General Public License, you may choose any version of the GNU Lesser
|
||||
General Public License ever published by the Free Software Foundation.
|
||||
|
||||
If the Library as you received it specifies that a proxy can decide
|
||||
whether future versions of the GNU Lesser General Public License shall
|
||||
apply, that proxy's public statement of acceptance of any version is
|
||||
permanent authorization for you to choose that version for the
|
||||
Library.

.SH DESCRIPTION
|
||||
|
||||
.B GPIO
|
||||
is a swiss army knife of a command line tool to allow the user easy
|
||||
access to the GPIO pins on the Raspberry Pi and the SPI A/D and D/A
|
||||
converters on the Gertboard. It's designed for simple testing and
|
||||
diagnostic purposes, but can be used in shell scripts for general if
|
||||
somewhat slow control of the GPIO pins.
|
||||
|
||||
It can also control the IO's on the PiFace IO board and load the SPI and I2C
|
||||
kernel modules if required.
|
||||
|
||||
Additionally, it can be used to set the exports in the \fI/sys/class/gpio\fR
|
||||
system directory to allow subsequent programs to use the \fR/sys/class/gpio\fR
|
||||
interface without needing to be run as root.
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||
.TP
|
||||
.B \-v
|
||||
Output the current version including the board revision of the Raspberry Pi.
|
||||
|
||||
.TP
|
||||
.B \-g
|
||||
Use the BCM_GPIO pins numbers rather than wiringPi pin numbers.
|
||||
\fINote:\fR The BCM_GPIO pin numbers are always used with the
|
||||
export and edge commands.
|
||||
|
||||
.TP
|
||||
.B \-1
|
||||
Use the physical pin numbers rather than wiringPi pin numbers.
|
||||
\fINote:\fR that this applies to the P1 connector only. It is not possible to
|
||||
use pins on the Revision 2 P5 connector this way, and as with \-g the
|
||||
BCM_GPIO pin numbers are always used with the export and edge commands.
|
||||
|
||||
.TP
|
||||
.B \-x extension
|
||||
This causes the named extension to be initialised. Extensions
|
||||
comprise of a name (e.g. mcp23017) followed by a colon, then the
|
||||
pin-base, then more optional parameters depending on the extension type.
|
||||
See the web page on http://wiringpi.com/the-gpio-utility/
|
||||
|
||||
.TP
|
||||
.B \-p
|
||||
Use the PiFace interface board and its corresponding pin numbers. The PiFace
|
||||
will always appear at pin number 200 in the gpio command. You can assign any
|
||||
pin numbers you like in your own programs though.
|
||||
|
||||
.TP
|
||||
.B read <pin>
|
||||
Read the digital value of the given pin and print 0 or 1 to represent the
|
||||
respective logic levels.
|
||||
|
||||
.TP
|
||||
.B write <pin> <value>
|
||||
Write the given value (0 or 1) to the pin. You need to set the pin
|
||||
to output mode first.
|
||||
|
||||
.TP
|
||||
.B aread <pin>
|
||||
Read the analog value of the given pin. This needs to be uses in
|
||||
conjunction with a -x flag to add in an extension that handles analog
|
||||
inputs. respective logic levels.
|
||||
|
||||
e.g. gpio -x mcp3002:200:0 aread 200
|
||||
|
||||
will read the first analog input on an mcp3002 SPI ADC chip.
|
||||
|
||||
.TP
|
||||
.B awrite <pin> <value>
|
||||
Write the analog value to the given pin. This needs to be used in
|
||||
conjunction with a -x flag to add in an extension that handles analog
|
||||
inputs. respective logic levels.
|
||||
|
||||
e.g. gpio -x mcp4802:200:0 awrite 200 128
|
||||
|
||||
will write the value 128 to the first DAC port on an mcp4802 chip on
|
||||
the Pi's SPI bus 0.
|
||||
|
||||
|
||||
.TP
|
||||
.B wb <value>
|
||||
Write the given byte to the 8 main GPIO pins. You can prefix it with 0x
|
||||
to specify a hexadecimal number. You need to set pins to output mode
|
||||
first.
|
||||
|
||||
.TP
|
||||
.B readall
|
||||
Output a table of all GPIO pins values. The values represent the actual values read
|
||||
if the pin is in input mode, or the last value written if the pin is in output
|
||||
mode.
|
||||
|
||||
The readall command is usable with an extension module (via the -x parameter),
|
||||
but it's unable to determine pin modes or states, so will perform both a
|
||||
digital and analog read on each pin in-turn.
|
||||
|
||||
.TP
|
||||
.B reset
|
||||
Resets the GPIO - As much as it's possible to do. All pins are set to
|
||||
input mode and all the internal pull-up/down resistors are disconnected
|
||||
(tristate mode).
|
||||
|
||||
The reset command is usable with an extension module (via the -x parameter),
|
||||
but it's limited to turning the pin into input mode (if applicable) and
|
||||
removing any pull up/down resistor.
|
||||
|
||||
.TP
|
||||
.B pwm <pin> <value>
|
||||
Write a PWM value (0-1023) to the given pin. The pin needs to be put
|
||||
into PWM mode first.
|
||||
|
||||
.TP
|
||||
.B clock <pin> <frequency>
|
||||
Set the output frequency on the given pin. The pin needs to be put into
|
||||
clock mode first.
|
||||
|
||||
.TP
|
||||
.B mode <pin> <mode>
|
||||
Set a pin into \fIinput\fR, \fIoutput\fR or \fIpwm\fR mode. Can also
|
||||
use the literals \fIup\fR, \fIdown\fR or \fItri\fR to set the internal
|
||||
pull-up, pull-down or tristate (off) controls.
|
||||
|
||||
.TP
|
||||
.B unexportall
|
||||
Un-Export all the GPIO pins in the /sys/class/gpio directory.
|
||||
|
||||
.TP
|
||||
.B exports
|
||||
Print a list (if any) of all the exported GPIO pins and their current values.
|
||||
|
||||
.TP
|
||||
.B export
|
||||
Export a GPIO pin in the \fI/sys/class/gpio\fR directory. Use like the
|
||||
mode command above however only \fIin\fR and \fIout\fR are supported at
|
||||
this time. Note that the pin number is the \fBBCM_GPIO\fR number and
|
||||
not the wiringPi number.
|
||||
|
||||
Once a GPIO pin has been exported, the \fBgpio\fR program changes the
|
||||
ownership of the \fI/sys/class/gpio/gpioX/value\fR and if present in
|
||||
later kernels, the \fI/sys/class/gpio/gpioX/edge\fR pseudo files to
|
||||
that of the user running the \fBgpio\fR program. This means that you
|
||||
can have a small script of gpio exports to setup the gpio pins as your
|
||||
program requires without the need to run anything as root, or with the
|
||||
sudo command.
|
||||
|
||||
.TP
|
||||
.B edge
|
||||
This exports a GPIO pin in the \fI/sys/class/gpio\fR directory, set
|
||||
the direction to input and set the edge interrupt method to \fInone\fR,
|
||||
\fIrising\fR, \fIfalling\fR or \fIboth\fR. Use like the export command
|
||||
above and note that \fBBCM_GPIO\fR pin number is used not not wiringPi pin
|
||||
numbering.
|
||||
|
||||
Like the export commands above, ownership is set to that of the
|
||||
calling user, allowing subsequent access from user programs without
|
||||
requiring root/sudo.
|
||||
|
||||
.TP
|
||||
.B unexport
|
||||
Un-Export a GPIO pin in the /sys/class/gpio directory.
|
||||
|
||||
.TP
|
||||
.B wfi <pin> <mode>
|
||||
This set the given pin to the supplied interrupt mode: rising, falling
|
||||
or both then waits for the interrupt to happen. It's a non-busy wait,
|
||||
so does not consume and CPU while it's waiting.
|
||||
|
||||
.TP
|
||||
.B drive
|
||||
group value
|
||||
|
||||
Change the pad driver value for the given pad group to the supplied drive
|
||||
value. Group is 0, 1 or 2 and value is 0-7. Do not use unless you are
|
||||
absolutely sure you know what you're doing.
|
||||
|
||||
.TP
|
||||
.B usbp
|
||||
high | low
|
||||
|
||||
Change the USB current limiter to high (1.2 amps) or low (the default, 600mA)
|
||||
This is only applicable to the model B+
|
||||
|
||||
.TP
|
||||
.B pwm-bal/pwm-ms
|
||||
Change the PWM mode to balanced (the default) or mark:space ratio (traditional)
|
||||
|
||||
.TP
|
||||
.B pwmr
|
||||
Change the PWM range register. The default is 1024.
|
||||
|
||||
.TP
|
||||
.B load i2c [baudrate]
|
||||
This loads the i2c or drivers into the kernel and changes the permissions
|
||||
on the associated /dev/ entries so that the current user has access to
|
||||
them. Optionally it will set the I2C baudrate to that supplied in Kb/sec
|
||||
(or as close as the Pi can manage) The default speed is 100Kb/sec.
|
||||
|
||||
.TP
|
||||
.B load spi [buffer size in KB]
|
||||
This loads the spi drivers into the kernel and changes the permissions
|
||||
on the associated /dev/ entries so that the current user has access to
|
||||
them. Optionally it will set the SPI buffer size to that supplied. The
|
||||
default is 4KB.
|
||||
|
||||
.TP
|
||||
.B gbr
|
||||
channel
|
||||
|
||||
This reads the analog to digital converter on the Gertboard on the given
|
||||
channel. The board jumpers need to be in-place to do this operation.
|
||||
|
||||
.TP
|
||||
.B gbw
|
||||
channel value
|
||||
|
||||
This writes the supplied value to the output channel on the Gertboards
|
||||
SPI digital to analogue converter.
|
||||
The board jumpers need to be in-place to do this operation.

=======

|

This is a simple utility to test the GPIO pins on your revision $revision
|
||||
Raspberry Pi.
|
||||
|
||||
NOTE: All GPIO peripherals must be removed to perform this test. This
|
||||
includes serial, I2C and SPI connections. You may get incorrect results
|
||||
if something is connected and it interferes with the test.
|
||||
|
||||
This test can only test the input side of things. It uses the internal
|
||||
pull-up and pull-down resistors to simulate inputs. It does not test
|
||||
the output drivers.
|
||||
|
||||
You will need to reboot your Pi after this test if you wish to use the
|
||||
serial port as it will be left in GPIO mode rather than serial mode.
|
||||
|
||||
Please make sure everything is removed and press the ENTER key to continue,

Pi's. The Revision 2 is readily identifiable by the presence of the 2
|

mounting holes.
|
