17. [STM32F429] A4988 스텝모터 구동

 

 

1. 부품 구입 및 연결도 

http://item.gmarket.co.kr/detailview/item.asp?goodscode=1640866563

기타 건전지 ￦990

 

 

http://item.gmarket.co.kr/detailview/item.asp?goodscode=1637061530

기타 모터 ￦8,700

모터 에는 12V를 넣어주고 보드 구동 전압은 STM32F429 에 보면 3V를 줄수 있는 핀이 있습니다.

그것과 연결 하였습니다.

 

2. CUBE 설정

LCD 및 터치 스크린 설정

16. [STM32F429] LCD + 터치 스크린 사용 방법

 

모터 설정

주파수 계산

90000000 / 3 / 40000 = 750 hz

 

입니다.

PE8 번은 DIR을 위해서 output으로 빼놓습니다.

 

3. 코드

일단 저처럼 V7이신분은

mpu_arm7.h 에서 에러

이 오류 부터 해결하세요

main.c 입니다.
