[TUT] Lý thuyết về code LED sao băng bằng ASM và KeilC cho 8051

Con này dùng IC LPD 6803 điều khiển PWM để điều khiển 3 bóng LED RGB

nếu có sẵn IC điều khiển PWM rồi thì chắc con led này cũng rất max và nó làm led sao băng thì có lẽ hơi phí.

Bác nào có thể giải thích giúp mình chi tiết hơn những code trên được không ak. Dùng delay thì mình hiểu, chứ ngắt đọc mãi chẳng hiểu được ý đồ từng dòng lệnh của bác chủ thớt..

Ai giúp bác ý với kìa!

**ppro** · 18-11-2013, 02:39

em đợi mãi đợi mãi mà chưa thấy 1 đoạn nào asm hết...tụi em ko có học C nên chẳng hiểu gì bác ơi

[Phần cuối] Led sao băng trái tim

Trước tiên là sorry tất cả các bác vì sự vô cùng chậm trễ nầy

. Giờ mình share code và cách làm led trái tim cho các bác nào còn FA nè chứ tui thì ổn định rùi

hjhj.
Hình ảnh làm led.

Video chạy cho code nè.

Link video tham khảo thêm tương tự nè. https://www.youtube.com/watch?v=PfU3KO658IU
Code làm theo là chạy, ai làm rồi up cái video lên youtube xem với nha.
Còn ai muốn hiểu code thì chịu ngâm cứu từ đầu và suy nghĩ tí chứ đừng hỏi tại sao và tại sao nha.
Còn nợ các bác cái code ASM, hy vọng sẽ có trong năm mới này. Hoặc ai giúp cái, tui sẽ hỗ trợ chỉnh sửa cho!

Trước tiên là sorry tất cả các bác vì sự vô cùng chậm trễ nầy

. Giờ mình share code và cách làm led trái tim cho các bác nào còn FA nè chứ tui thì ổn định rùi

Video chạy cho code nè.

Link video tham khảo thêm tương tự nè. https://www.youtube.com/watch?v=PfU3KO658IU
Code làm theo là chạy, ai làm rồi up cái video lên youtube xem với nha.
Còn ai muốn hiểu code thì chịu ngâm cứu từ đầu và suy nghĩ tí chứ đừng hỏi tại sao và tại sao nha.
Còn nợ các bác cái code ASM, hy vọng sẽ có trong năm mới này. Hoặc ai giúp cái, tui sẽ hỗ trợ chỉnh sửa cho!

[MENTION=74931]tienhuypro[/MENTION] cho mình hỏi ! Code kia thì mình đã hiểu nhưng phần display này thì mình cho vào phần nào trên trương trình vậy , mình ko chuyên về cái này nhưng cũng nghịk ngợm chút cho đỡ buồn , mà cho mình hỏi là thạch anh dùng là 24M hay 12M , bạn trở lời gấp giúp mình nhé , mÀ nếu bạn có lòng thì cho mình luôn cái file Hex cho nhanh , inbox cho mình cũng được , mình đỡ phải lọ mọ

thank bạn trước

Bạn qua link này nhé.cuối bài viết code đã compile và xuất hex theo yêu cầu..Led trái tim sao băng code C full - Version Final | Blog Điện Tử | Tin Học - Chia sẻ kiến thức- Kết nối đam mê Điện Tử

chào CHíp , mình đã nạp thử cả 2 trương trình , của bạn và của bạn huy nhưng kết quả ko giống video chút nào , lét chỉ tối đi chứ chưa tắt hẳn , sao băng chậm , mình đã thử cả thạch anh 12M và 24M kết quả đều thế , nhìn rất chán , bạn có cách nào giúp mình đc không , mình cũng là dân điện tử nhưng mà chuyên về mảng khác , nên cách kết nối và hàn gắn linh kiện thì bạn khỏi phải lo , không biết thế nào ! giờ đâm ra chán

mọi người ơi bài này nạp cho mạch nối thứ tự port từ phải qua trái lần lượt là P0>>P2>>P3>>P1
mình mua mạch sẵn nó lắp lần lượt P2>>P3>>P1>>P0
có cách nào chỉnh sửa phần mềm theo mạch được k ạ.
mong mọi người giúp mình vs.
mình đã chỉnh code lại nhưng k đúng thì phải. nó vẫn vậy.

Còn cách PWM cho LED full (IC LPD6803) thì sao nhỉ? có bạn nào ý kiến gì không?

Con này có bộ điều khiển sẵn rồi, nó là lại led full colourl, Tùy theo lại IC điều khiển mà có bộ điều khiển và chuơng trình khác nhau,. IC LPD6830, D705, 1101 loại này có chân Vcc, GND, 1 chân DATA, và 1Clock để điều khiển, sử dụng CPU controller T1000S, các phần mềm tạo hiệu ứng như Ledwaker, LedEdit ...,> nói chung, Loại LED full màu này, tùy vào IC điều khiển mà có bộ điều khiển và phần mềm điều khiển khác nhau.

Mọi nguòi có thể xem video về loại LED này.

theo mình cái này dùng 74hc595 nói chung mạch này mình làm rồi board khá bự, và khá loằng ngoằng. tiện đây cho mình hỏi chạy kiểu sao băng dùng bộ 74hc595 ai có code chuẩn up lên cho mọi người cùng ngâm dc không>> thanks
