as7341-spin

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the ams AS7341

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.

Salient Features

  • I2C connection at up to 400kHz
  • Read sensor data (ADC words)
  • External LED control: power on/off, set drive strength
  • Set ADC integration time
  • Interrupts: set mask, threshold, source channel, sleep-after, read source(s), clear, sleep after interrupts, duration/persistence
  • FIFO ops: flush, set interrupt threshold, data source, get number of unread entries, read data
  • Flicker detection: set gain, enable AGC, AGC max level, detection time, interrupt persistence
  • Spectral engines: set gain, enable AGC, AGC max level, hysteresis, auto-zero (initiate manually, or set periodic)
  • Read status/flags: sensor saturation status, fifo overrun, flicker-detection error, initialization/busy, over-temperature error, spectral engine trigger error
  • Sensor SMUX configuration, write commands, registers

Requirements

P1/SPIN1:

  • spin-standard-library

P2/SPIN2:

  • p2-spin-standard-library

Compiler Compatibility

Processor Language Compiler Backend Status
P1 SPIN1 FlexSpin (6.9.4) Bytecode OK
P1 SPIN1 FlexSpin (6.9.4) Native/PASM Build OK, runtime bad
P2 SPIN2 FlexSpin (6.9.4) NuCode Not yet implemented
P2 SPIN2 FlexSpin (6.9.4) Native/PASM2 Not yet implemented

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

Limitations

  • Very early in development - may malfunction, or outright fail to build
  • Method names and API should be considered unstable/tentative
