Cần giúp đỡ sửa lỗi Quang báo led matrix 8x32

[hoangdt29]

Mình có nghiên cứu viết code và mô phỏng protuels khi không có mạch công suất là ULN2803 và transistor thì mạch chạy tốt, nhưng sau khi thêm công suất vào thì mạch bị nhiễu. mong mọi người giúp đỡ mình tìm hiểu là code sai chỗ nào. Do code mình viết còn nhiều sai sót và thuật toán chưa triệt để, mong mọi người góp ý thêm cho mình. Mình suy đoán là bị lỗi ở phần chốt dữ liệu ra con 595. Mình quét hàng, và đưa dữ liệu ra 595. Dùng phương pháp offscreen (cái này cũng chưa chắc chắn do code còn gà, dùng khá khá vòng lăp). Tính làm để tết lắp cho vui mà chắc không thành công rùi. Mong mọi người góp ý nhiều nhiều để mình có thể học hỏi được nhiều điều. Có gì code không hiểu mình sẽ giải thích. tks mọi người (mình có gửi flie mô phỏng và code: test2)

chào bạn, bạn đã làm thật mạch này chưa?

[hoangdt29]

Chưa bạn à, cái này mình viết tìm hiểu thuật toán thui, thường thì không viết theo cách này đâu
