STM32H7 Arduino 로 TFTLCD ST7789 모듈을 제어 해 보자
TFT LCD 라이브러리는 FTF_eSPI 를 사용하여 테스트 했다.

셋업 방법
Arduino\libraries\TFT_eSPI
폴더에 User_Setup_Select.h 파일에 보드에 따른 설정파일을 지정해 주어야 한다.
#ifndef USER_SETUP_LOADED // Lets PlatformIO users define settings in
// platformio.ini, see notes in "Tools" folder.
// Only ONE line below should be uncommented. Add extra lines and files as needed.
//#include <User_Setup.h> // Default setup is root library folder
//#include <../TFT_eSPI_Setups/Setup24_ST7789_rp2040_riexp.h>

폴더에 Setup_ST7789_stm32h7_evm.h 파일을 만들어서 작성했다.

TFT_eSPI 라이브러리에서 제공하는 다양한 예제를 테스트 해 보면 잘 동작하는것을 확인 할 수 있다.
