hỏi về nháy led bằng dspic

[hang1988]

Bạn hãy tham khảo code này! Code nháy 8 LED đơn giản! Cần gì dùng timer cho phiền ra! để đó còn ùng cái khác!

										CHUONG TRINH NHAY LED DON - DSPIC30F4011  

+ Phan cung :             Dung LED don  noi vao RB0 - RB7 ----------------------
+ Yeu cau : Nhay tu 0 den 7 va 7 ve 0 . Sau do nhap nhay linh tinh
