[3DP] Ender 3 Dual Extruder 개조: Marlin @Creality Board

0. Board는 V4.2.3 인데 cpu가 GD32F303 RET6 이다 :-(

1. 검색해서 Ender 3 Neo ( V2 Neo 아님) Firmware를 찾았다.

2. STM32F101로 설정하고 컴파일하니 에러 발생

In file included from src\src\HAL\STM32\MarlinSPI.cpp:27:
src\src\HAL\STM32\MarlinSPI.h:99:3: error: 'spi_mode_e' does not name a type

다시 고난의 연속이다

I compiled with default_envs = STM32F103RE_creality_maple in platformio.ini

똑같은 에러

STM32F103RE_creality_maple로 하면

기존 marlin 프로젝트에서 보드만 바꿔서 해봐야겠다.

-> 기존 프로젝트에서 configuration.h의 board를 바꾸니 바로 autobuild가 인식한다.

configuration.h/_adv.h 를 example를 참고하여 수정했더니 아래처럼  _maple 이 나온다

에러

_maple로 빌드

configuration.h에 몇가지 잘못된 거 수정했더니 양쪽 모두 빌드 성공

SD Card로 firmware update 는 되었지만, 메뉴 선택 노브가 동작을 안한다.

-> 다시 원본으로 시도

복구는 되었으나 메뉴 선택이 안된다 !!!
