Ai xem hộ code LED ma trận 8x32 dùng thanh ghi dịch 74HC595 của mình sai ở đâu ?

[hieult153]

Mình đã làm mạch mô phỏng và viết code...nhưng chạy chưa được...có lẽ là code bị sai...mọi người xem hộ mình cái nhé ! Thanks.

strlen là hàm gì thế nhỉ :3

[tranvanlac]

hàm strlen() dùng để tính độ dài của một chuỗi bạn puccadangiu
