This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the MAXIM MAX30102 Pulse Oximeter and Heart Rate 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 up to 400kHz
- Set ADC resolution
- Read various status flags: FIFO overrun, FIFO full, number of FIFO unread samples, interrupt status
- Enable interrupts: FIFO threshold, new data ready, ambient light cancellation overflow, die temperature data ready
- Set red and IR LED currents individually (0..51000uA)
- Set optional sample averaging
- Set sample rate
- Set full-scale range
- Read die temperature
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM I2C engine (none if the bytecode-based engine is used)
