giúp em phần mềm keil c này với

[bitbabon170]

có ai giúp em sửa lại phần hiển thị led 7 doan với, e đang làm đồng hồ số, mà e nạp code vào ic nó ko chạy mà sáng hết led lên có a nào sửa lại giúp e đoạn code này ko, e cám ơn nhiều. đoạn e tô màu nha.

chương trình này khá giống của mình, chỉ khác là có người đã thêm cái đọc ADC vào thôi. và mình đảm bảo rằng chương trình hiển thị time ngon lành ko vấn đề j, nếu ko chạy thì hãy kiểm tra lại phần cứng đi, cái này làm mạch thực tế nhiều rồi.

[bitbabon170]

mình kiểm tra hết rồi, và củng hỏi thầy và thầy bảo là bị lổi phần mả code ở led 7 đoạn ko xuất được ra led
