LTC4150 Module

English | 简体中文

---

Environment and Relevant Pins：

This program is based on STM32F103, with the INT pin connected to PB7, the POL pin to PB6, and the SHDN pin to PB5.

Functionality:

By inputting the total battery capacity in mAh and the current battery percentage, the program calculates the remaining battery capacity and, optionally, the current. It also provides an I2C-connected OLED screen to display the data.

Notes:

The program uses interrupts, so you need to close SJ1 on the LTC4150.

If you want the output voltage to be set to 3.3V, close SJ2 and SJ3. For 5V output, leave them open.

Description:

This program is a port of the official Arduino code to STM32F103.
