[GD32F-48 SSM EVM] GD32F303 Arduino 만들기

 

GD32F303을 Arduino로 사용하기위해  보드파일을 하기 링크를 이용하였다.

https://github.com/keyboardio/ArduinoCore-GD32-Keyboardio

GitHub - keyboardio/ArduinoCore-GD32-Keyboardio: Arduino core for GD32 devices, community developed, based on original GigaDevic

 

Arduino IDE 에서 Board 파일을 등록 해 주고 GD32로 검색해서 설치 할 수 있다.

보드를 GD32F30x Generic series 로선택하고 Board part number를 GD32F303를 선택 해 주면 된다.
