This is a P8X32A/Propeller 1, P2X8C4M64P/Propeller 2 driver object for the Melexis MLX90621 IR thermometer
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 100kHz
- Reads IR channels 1 and 2 (ch2 availability dependent on device package)
- Reads ambient temperature sensor
- Returns temperature in centi-degrees (hundredths) Kelvin, Celsius or Fahrenheit
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM I2C engine (none if the bytecode-based engine is used)
- sensor.temp.common.spinh (source: spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- sensor.temp.common.spin2h (source: p2-spin-standard-library)
