Mình có mạch led ma trận như trên.Mình viết code chạy chữ được rồi,mình thực hiện quét cột và gởi dữ liệu ra hàng.bây giờ mình muốn thêm cổng not thay cho uln2803 trong mô phỏng để làm mạch thực tế nhưng khi thêm cổng not vào ngõ ra của ic74595 thì mình sửa code lại nhưng mô phỏng không chạy.Mong mấy bận gợi ý mình cach sửa code .thanks
code đây :
