Giúp code đồng hồ 60 led viền dùng 8051+595

[hoangthong09]

Tình hình là mình định làm cái đồng hồ số 60 led viền để trang trí cho đẹp nhà..nhưng mà tìm trên mạng thì thấy mấy bài đăng chỉ có code cho 1 hiệu ứng theo giây..xem trên youtube thì thấy rất nhiều hiệu ứng đẹp..nhưng toàn là sản phẩm thương mại kg share code..nên mình mày mò tìm hiểu viết code cho viền 60 led, mình mới viết thử nhưng gặp vấn đề là khi tăng hiệu ứng thì khi hết hiệu ứng cái led nhảy giây lại sai..có độ trễ và kg bắt đầu lại từ led đầu tiên..mong m.ng bớt chút time để giúp mình hoàn thiện ạ....
Code mình đây ạ...
