This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the VEML7700 ALS/Lux sensor.
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 ~28kHz (P1: bytecode I2C) or up to 400kHz (P1: native code I2C, P2)
- Measure illuminance in lux (0.00001 units), get max possible reading with current settings
- Read ADC word for ALS and white channels
- Set sensor gain and integration time
- Interrupts: set thresholds, read flags, set duration in cycles
- Power: power sensor on/off, enable power saving modes
P1/SPIN1:
- spin-standard-library
- 1 additional core/cog for the PASM-based I2C engine (or none if the bytecode-based engine is used)
P2/SPIN2:
- p2-spin-standard-library
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.9.4) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.9.4) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | NuCode | OK |
| P2 | SPIN2 | FlexSpin (6.9.4) | Native/PASM2 | OK |
(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
- TBD
