MOV R1,0 ; ma khoi dau
MOV R2,#256 ; so bang ma
MOV R3,#4 ; xuat 4 byte ra 4 con 595
mov dptr,#mydata

LOOP1: mov r4,#8 ; xuat 8 bit ra 595
mov a,R1
movc a,@a+dptr

loop2:

cảm ơn các anh nha....chạy được rồi. a có thể cho e cái yahoo hay facebook hoặc mail được không? khi nào gặp rắc rối thì gỡ rối giúp em.
e chưa được học môn vvi điều khiển nên chưa biết gì cả.

[hocxa_nhonha]

giờ e muốn dùng thêm port khác để điều khiển mấy con 595 khác thì phải khai báo và sửa đợn 010110 như thế nào?

[01642555134]

Phài có mục đích, mới làm, nói như vậy, ko ai hiểu, nên ko thể giúp dc, phải cụ thể

[hocxa_nhonha]
