hix !! ko ai giúp em à :-s

[mast090]

chắc là dân chơi C nhiều hơn dân chơi ASM, mà dân chơi ASM đang ẩn dật ^_^

[bgdientu]

nhìn cái đoạn DB ............. mà hoa hết cả mắt chắc nhìn thêm chút nữa là em sỉu mất.

[chumanh]

muốn quét tốt led 16x64 cậu nên tìm hiểu các ic liên quan tới công việc này rồi hãy tính tới chuyện đọc hiểu code ! việc hiểu đc code cũng ko quá khó nếu cậu chịu khó chạy debug mô phỏng

[ngocchuong90]

em cũng đã hiểu nhiệm vụ của mấy con IC trong đó rùi ! Cái thuật toán thì đầu tiên là đọc bảng dữ liệu, sau đó thì xuất ra ! nhưng ở đây em thấy sử dụng truyền tin nối tiếp ! mà em ko biết dòng code nào làm nhiệm vụ ấy ! hix ! mới lại ở đây dùng ngắt nữa :-s những cái này em hok biết
tuần sau em phải nộp rùi :-s các bác giúp em với :-s

[ngocchuong90]

help me :-s

[anhhungxalo]

nhìn thấy chóng cả mặt, nhức hết cái đầu. Sao bạn không liên hệ với tác giả viết cái code này đi.

Chào các bạn,

Hồi sinh viên mình đã làm mạch quang báo với 4 matrix LED 8x8. Hiện mình vẫn còn giữ thiết kế và code. Mình up lên đây cho các bạn quan tâm có thêm tài liệu để nghiên cứu.
Chúc các bạn thành công.
