This is a P8X32A/Propeller driver object for the Silicon Labs Si114x (5, 6, 7) series UV/Proximity/Ambient light sensors.

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

• I2C connection at up to 3.4MHz (tested at 400kHz)
• Read ambient light sensor (IR, Visible) raw data
• Read Auxiliary and UV data channels (UV index unverified)
• Flags indicating measurement overflow for IR and visible light sensors
• One-shot and continuous measurement modes
• Set IR and Visible light sensor gains
• Set custom UV index calibration coefficients
• Measure illuminance, in lux

P1/SPIN1:

• spin-standard-library
• 1 extra core/cog for the PASM I2C engine

P2/SPIN2:

• p2-spin-standard-library

(other versions or toolchains not listed are not supported, and may or may not work)

• Very early in development - may malfunction, or outright fail to build
• Doesn't support proximity sensor function
• Doesn't support alternate slave address usage/programming
• Doesn't support temp sensor/Vdd/Vss reading (not currently planned)
• Measurement calibration/correction/calculation unverified
