1. 부품 중에 주파수 조절/발생기 연결 방법 부탁드립니다.
1) Vin +
2) Vin -
3) PWM
4) GND
이렇게 각각 연결해야 하는 것 같은데, GND는 연결 가능한데 Vin +,- 와 PWM을 어디에 연결해야할지 모르겠습니다.
2. 기판을 작동시키고, 다른모드에서 다른화면으로 넘어갈때, 이전 화면에 있던 글씨들이 겹치지 않는 부분은 그대로 다음화면으로 넘어가는데.. 코드값 중에 어디가 잘못된건가요??(사진 첨부하겠습니다.)
3. 온도센서가 아무런 조작을 안했는데도 너무 범위가 넓게 왔다갔다하는데 9도~ 20도 혹시 코드값 문제 있는지 확인 좀 해주실 수 있으실까요?
코드값 참고 부탁드립니다.
