CCS C for PIC16F877A

[LEO-XBS]

các bác xem thử một chương trình nhé. ở đây em chỉ viết các modul chương trình con thực hiện chức năng của robot còn chương trình chính thì sẽ gọi các chương trình con tùy theo mình muốn dùng chức năng nào của robot.

namqn: bạn nhớ dùng các tag [ code] và [ /code] để bọc các đoạn mã nguồn, như vậy sẽ dễ đọc hơn (nhớ là các tag không có khoảng trắng nhé).
