The SI1133 from Silicon Labs is a UV Index Sensor and Ambient Light Sensor in a small 2x2 mm DFN package. The sensor can measure independently ultra violet (UV) light, infra red (IR) light and ambient light, however the ambient light is also influenced by the IR light requiring compensation from the IR readings. The SI1133 is quite different from other Silicon Labs chips in RIOT OS and therefore needs its own driver. In particular, the SI1133 has 7 different photodiode configurations to read but only 6 channels to read them in parallel so only some channels can be read each time. This patch implements a new driver allowing to read the data directly and a saul interface for the three kinds of light source. There are many configuration options including interrupts and continous modes that are left out of this initial driver. |
