STM32_I2C_LCD

This I2C LCD library project file is implemented in STM32CubeIDE.

이 프로젝트의 I2C LCD 라이브러리 파일은 STM32CubeIDE 내에서 구현됩니다.

STM32 HAL library for LCD display based on 16x2 CLCD with PCF8574 Currently, the "stm32f4xx_hal.h" library is used. You must include and use the appropriate library for your board.

The source and header files are placed in Src/liquidcrystal_i2c.c and Inc/liquidcrystal_i2c.h respectively. After including the header file suitable for the STM32 MPU, write the Device I2C Address.

#include <LiquidCrystal_I2C.h>
