아래에 제가 짠 소스를 올려봅니다.
대충 돌아가니까 올리기는 하는데...
아직 뭔가 조금 이상한 부분이 남아 있습니다. ^^

SLM1606M 데이타시트에 있는 Con2 부분에 대한 제어가 아직 미짐쩍어서..
하지만 신경쓰지 않기로 했습니다. ^^

SLM1608 로 바뀌면서 아예 제가 미심쩍어하는 부분은 빼버렸더군요... ^^
그냥 1606을 1608처럼 사용하는 소스...

(여전히 한군데 약간 이상한 구석(버그)이 남아있는 프로그램입니다. ^^)
혹시 SLM1606 이나 1608 구하게 되시면 이 소스 이용해서 프로그램해 보세요. ^^
연결하는 법은 소스 맨 앞쪽에 나와 있습니다.
