SparkFun MAX17043 Particle Library

Firmware library SparkFun's Photon Battery Shield and the MAX17043 Breakout.

About

This is a firmware library for SparkFun's Photon Battery Shield.

Photon Battery Shield.

The MAX17043 interfaces between a LiPo battery and a microcontroller. The MAX17043 can read a battery's voltage and, using a sophisticated battery-modelling algorithm, estimate the state of charge (SOC).

Repository Contents

  • /doc - Additional documentation for the user. These files are ignored by the IDE.
  • /firmware - Source files for the library (.cpp, .h).
  • /firmware/examples - Example sketches for the library (.cpp). Run these from the Particle IDE.
  • spark.json - General library properties for the Particel library manager.

Example Usage

Include the MAX17043 library:

#include "SparkFunMAX17043.h" // Include the SparkFun MAX17043 library

Then use the lipo object to interact with it. Begin by initializing the IC:

void setup() { // Set up the MAX17043 LiPo fuel gauge: lipo.begin(); // Initialize the MAX17043 LiPo fuel gauge

// Quick start restarts the MAX17043 in hopes of getting a more accurate // guess for the SOC. lipo.quickStart();

// We can set an interrupt to alert when the battery SoC gets too low. // We can alert at anywhere between 1% - 32%: lipo.setThreshold(10); // Set alert threshold to 10%. }

Then you can read the voltage and state-of-charge (SOC) values like this:

// lipo.getVoltage() returns a voltage value (e.g. 3.93) voltage = lipo.getVoltage(); // lipo.getSOC() returns the estimated state of charge (e.g. 79%) soc = lipo.getSOC();
