pmsa003i-spin

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the PMSA003i particle concentration 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.

Salient Features

  • I2C connection at up to 100kHz (P1 PASM I2C engine, P2), ~28kHz (P1 bytecode I2C engine)
  • Read concentration of 1.0, 2.5, 10.0 micron particles, in micro-grams per cubic meter
  • Checksum performed on all data read from sensor

Requirements

P1/SPIN1:

  • spin-standard-library
  • 1 extra core/cog for the PASM I2C engine (none if the bytecode I2C engine is used)

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 OK
P2 SPIN2 FlexSpin (6.9.4) NuCode Untested
P2 SPIN2 FlexSpin (6.9.4) Native/PASM2 OK

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

Limitations

  • TBD
