mọi người giúp tôi về cách sử dụng ic 74ls595 và uln2803 trong làm mạch ma trận..dưới đây là code của ma trận.mọi người giúp tôi xem dãy lệnh nào trong chương trình này thực hiện chức năng chạy chữ từ phải sang trái.ai đó giúp tôi vẽ lưu đồ thuật toán chương trình này được không.mong mọi người giúp đỡ tôi rất cần.

[ckddt13]

ai đó giải thich giúp tôi chương trình này.chương trình này chạy chữ trên led matran.từ phải sang trái.a e xem dãy lệnh nào thực hiện chức năng chạy chữ từ phải sang trái.điều khiển chạy 2 dòng chữ thong qua nút bấm.ai đó giúp tôi vẽ lưu đồ thuật toán chương trình này được không

Giờ bạn kêu làm mới thì còn được..hihi...Bạn muốn làm ntn nói cụ thể ra mình và mọi người sẽ giúp...Code lại nhanh thôi.

[ckddt13]

tôi chẳng biết pót lên như thế nào.mong bạn thông cảm.mà chương trình trên cũng chỉ rõ rùi mà.tôi nói sơ về phần cứng như sau:vdk 89c51,ma trận 8x64 <=>8 ma trận 8x8 ghép lại. <=>sử dụng 8 con 595 nối ra 8 led ma trận (Q0=>Q7)(nối với cột của ma trận,để led nằm thẳng đứng,có dùng tzt).có lẽ bạn cũng biết để làm gì tôi không nòi thêm.chân DS nối với p2.0,chân SH,ST CP được nối chung với nhau và nối vào p2.1,chân còn lại chắc ko phải nói.cổng p1 được nối với uln 2803.đầu ra 2803 được nối với 8 hàng của led ma trận.p3.0 và p3.1 nối với nút bấm để điều khiển 2 chương trình(2 dòng chữ,mỗi nút bấm là một dong chữ).


mong bạn xem dãy chương trình trên,đ dãy lệnh nào thực hiện chức năng chạy chữ từ phải sang trái.và giúp tôi vẽ lưu đồ thuật toán cho chương trình đó.mà giải thích tất cả các dãy lệnh trên giup tôi cang tot.

[ckddt13]

tôi chỉ cần bạn xem dãy lệnh nào ở chương trình trên thực hiện chức năng chạy chữ từ phải sang trái.và giúp tôi vẽ lưu đồ thuật toán cho chương trình đó.mà giải thích tất cả các dãy lệnh trên giup tôi cang tot.

mong mọi người giúp đỡ.code ở trên,phần cứng tôi cũng mô tả rõ ràng ở trên.thanks

TRỜI ƠI TRỜI QUÁ OẢI....

nếu bạn hiểu thì cảm ơn tui 100 cái !

[ckddt13]

thanks ban 100 cái.toi da hieu.nhưng vấn đề đặt ra là tôi chưa hiểu vẽ lưu đồ thuật toán ra sao.tôi mong bạn giúp tôi thêm vấn đề này.thanks ban 1000 lần.hj.bởi vì tôi đang làm đồ án học phần cần rõ điều này

[takado]

hix vậy là code bạn đã làm xong rồi còn lưu đồ thôi chứ gì, bạn gõ đồ án led ma trận trên google thì có mà đầu thuật toán, các thầy cũng không dỗi hơi đi xem thuật toán của bạn đúng hay sai đâu miễn là hợp lý là được

[ckddt13]

thanks.vâng tôi chỉ còn lưu đồ thôi.thấy vẽ phức tạp quá.tìm mãi không thấy.cả google cung vậy.có lẽ phải vẽ bừa một cái như bạn nói.hix.nói như bạn thì cái gì cũng làm bừa cho xong.dù sao cũng xin cảm ơn.

bác "Takado" ơi. em đang nghiên cứu cái code C giống của bác. còn mỗi cái thắc mắc là tại sao lại dùng timer 0 chế độ 16 bít vậy??
bác coi giúp em cái code này với. khi nào thì nó ngắt. Do tìm hiểu thì ngắt chỉ xảy ra khi cờ TF tràn. mà timer thì không nạp lại.....Đang kẹt chỗ này.
8x32.rar file đính kèm về code và mô phỏng
p/s sau khi đo xung nhip thi viec nap với không nạp tl0 và THo là như nhau. thời gian ngắt đo được là khoảng 40ms....
các bác chỉ giúp.
với C hiện vẫn là hạng ruồi, chưa lên hạng gà hic
