max30102-spin

---

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.

Salient Features

• 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

Requirements

P1/SPIN1:

• spin-standard-library
• 1 extra core/cog for the PASM I2C driver

P2/SPIN2:

• p2-spin-standard-library

Compiler Compatibility

• P1/SPIN1: OpenSpin (tested with 1.00.81)
• P2/SPIN2: FastSpin (tested with 4.2.3-beta)
• BST (incompatible - no preprocessor)
• Propeller Tool (incompatible - no preprocessor)
• PNut (incompatible - no preprocessor)

Limitations

• Very early in development - may malfunction, or outright fail to build
• Doesn't calculate HR or SpO2

TODO

• Combine Interrupt1() and Interrupt2()
• Port to SPIN2/P2
• Add methods to calculate HR and SpO2
