lập trình các loại module led ma trận P10, P5 loại 1 màu và loại full màu. trong bài viết là full code của một phần dự án mình làm, nhưng nó đầy đủ tính năng để có thể hiển thị yêu cầu mong muốn như ảnh đính kèm. nếu bạn cần hỗ trợ hoặc hợp tác công việc thì hãy liên hệ với mình qua zalo: 097752155ba
Tìm hiểu chung về các loại module led
- Hiện trên thị trường có nhiều loại module Led matrix,…
- Cách đọc thông số 1 tấm module LED matrix: hàng cột, kiểu quét,…
(xem video trong danh sách phát “LED MATRIX” trên kênh youtube :

Module led matrix P10 DIP RED LED SCAN 1/4
- Cách kiểm tra hướng dịch dữ liệu và kiểu quét của tấm led để code phù hợp: trên kênh Youtube
- Dưới đây là code mẫu hiển thị “tĩnh” 1 tấm Led P10 kiểu quét 1/4 : ảnh minh họa loại led chứ code ko hiển thị như ảnh

Liên hệ công việc, hợp tác
- Nếu bạn cần một thiết kế phần cứng hoặc hỗ trợ, kết nối hiển thị data cho các loại led trên thông qua truyền thông thì mình có nhận code và thiết kế nha, ngoài ra mình còn nhận thiết kế các loại mạch khác, ứng dụng Iot, cần liên hệ :
