hihi mình cũng mới học nên chịu đấy hi jo muôn hoc vdk mà ko biết học cái j?ko làm thế nào mấy bạn viết code giỏi thi lần sau đăng code viết chú thích đằng sau câu lênh để minh học với ??ko minh nhin hoa hết mắt hiComment

phần led hiển thị đâu hả bác?Nguyên văn bởi chumanh Xem bài viếtXem chừng là diễn box 8051 đang sôi động với đồng hồ số và đo nhiệt độ các loại
, hôm nay rảnh ngồi send cho ae nào quan tâm tới vấn đề này. Một cái project mình làm đầy đủ cả, bạn nào thích thì load về lắp chơi nhé.
