Python module for the APDS-9930 I2C Ambient Light and Proximity sensor
This is a Python port of the AVR APDS-9930 library.
Simple and easy to use. Makes heavy use of Python-specific programming concepts, such as properties, to make usage even easier. Depends on python-smbus, the I2C library for Python.
It will be deleted without reading. If you have an issue, create an issue here on GitHub.
I'm not going to maintain this library any more. I will merge pull requests, though. Contributions are welcome. Just don't expect anything from me.
I tested this on Linux a desktop computer, using the I2C pins of a nVidia graphics card, using the Nouveau graphics driver. This has been reported to work for both ATI and nVidia cards, but not for integrated Intel (and I can confirm this).
Check the pinout:
| Color | Pin | Usage |
|---|---|---|
| Gray | 5 | GND |
| Red | 9 | +5V/VCC |
| Yellow | 15 | SCL (serial clock) |
| Blue | 12 | SDA (serial data) |

It should work on Raspberry PI. I'll be testing it on a Raspberry PI 2 as soon as I get it.
Load the i2c-dev kernel module.
sudo modprobe i2c-dev
Install i2c-tools to get the i2cdetect program, useful to scan for I2C devices.
sudo apt-get install i2c-tools
List the I2C buses
sudo i2cdetect -l
Connect the device to the I2C pins, then scan every bus until you find the device. Device should have address 0x39.
sudo i2cdetect -y <bus number>
# Sample good output

Once you have found the correct bus, run Python as root and import the module.
sudo python
>>> from apds9930 import APDS9930
Open the bus
>>> a = APDS9930(bus_number)
