Simon Albinsson 8bff008b36 More stable time keeping and Using new init-functions

The old time keeping routine was a bit flaky, this one might blow up in
 irritating ways if a cycle takes more than 1 second. Also uses the new
 init functions to set up the SGP.
 Be ware of the dangerous i2c-general call that resets any device on the
 buss that listens to general call.

RPI_SGP30

Program to read eCO_2 and TVOC from the SGP30 sensor. Based on the smbus2 i2c library for ease of use.

It currently lacks support for many features features and is more of a crude demo than a proper library.

Features that are known to be missing (listing in rough order of importance):

CRC support
reading/writing base-line data
reading raw-values
Proper structuring of the code

If you have the AdaFruit board with built in level shifters and voltage regulator it is should work if you just plug in SDA to pin 3, SCL to pin 5, VCC to pin 17 and GND to pin 20. You should then be able to find the SGP30 an address 0x58 using i2cdetect -y 1. If you get an error message you probbably need to enable i2c in the kernel using raspi-config and reboot
