MAX1704x/MAX17043/MAX17044/MAX17048/MAX17049 - Battery gauge

Library designed for controlling MAX1704x IC.

Functions

The binding supports all functionalities for MAX1704x family. Implemented based on SparkFun implementation.

Classes

  • Max17043 - class for MAX17043
  • Max17044 - class for MAX17044
  • Max17048 - class for MAX17048
  • Max17049 - class for MAX17049
  • Max1704x - base class for all max IC

Usage

// Make sure your pins are configured correctly especially for ESp32
var i2cDevice = I2cDevice.Create(new I2cConnectionSettings(1, Max1704X.DefaultAddress));
var max = new Max17048(i2cDevice);
Console.WriteLine($"Voltage: {max.BatteryVoltage.Volts} V");
Console.WriteLine($"Percent: {max.BatteryPercent.Percent} %");

Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice.
