mình có down trên diên đàn code led ma trận 8x32 không nhớ của ai về chạy mô phỏng thì ok nhưng khi làm mạch thật thi không chạy. không biết sai ở dâu,thạch anh sử dụng là 12MHZ và 2 tụ 30p tụ rest 10uf , về phần 74595 mắ chân 16 và chân 10 cấp lên +5v chân 8 và 13 nối xuống -5v,chân 14 nối p2.0 chân 11 nối p2.1 chân 12 nối p2.2 32 cổng ra của 74595 qua 32 trans C1815 đệm dòng cho 32 cột led (anot chung) và 8 chân của p1 nối qua trở 220 om vào 8 hàng (knot chung) nhưng van không chạy .moi ngừoi xem hộ mình sai ở chỗ nào ,dịnh làm cai chơi têt mà bị xịt ngay từ lần đầu nản quá
đây là file mô phỏng và code ,file *hex
