lc709204f's Introduction

LC709204F

Arduino library for the LC709204F battery monitor.

This library was developed and tested on the RedPill+ (ESP32-S3) module, which has an onboard LC709204F and onboard thermistor.

RedPill+ (ESP32-S3) is available at munich-labs.com.

Contents

Installation

To install the library in the Arduino IDE, open Tools > Manage libraries..., type LC709204F in the search box and click Install.

Usage

The library comes with and example which is a good starting point.

Include the library in your project and define the battery monitor:

#include "LC709204F.h"

LC709204F batteryMonitor;

In the setup section initialize the LC709204F according to your setup:

batteryMonitor.init(lc709204f_apa_adjustment_t::LC709204F_APA_1000MAH, lc709204f_battery_profile_t::LC709204F_BATTERY_PROFILE_3_7_V)

Use the batteryMonitor to read/write parameter:

batteryMonitor.getCellVoltage()

The init requires two parameters:

  • APA (Adjustment Pack Application): Sets the battery capacity
  • Change Of The Parameter: Sets the battery profile/type

There are predefined values for both these parameters.

For APA, chose one of the following values (or the closest one to your battery):

  • LC709204F_APA_50MAH

For the battery profile, chose one of the following values:

  • LC709204F_BATTERY_PROFILE_3_7_V (3.7V charging at 4.2V)
  • LC709204F_BATTERY_PROFILE_UR18650ZY_PANASONIC (UR18650ZY (Panasonic))
