Lập trình ASM cho 8051

Trong thời gian qua khắp các diễn đàn từ Bắc chí Nam truyền nhau một bài hát do thầy Bùi Như Lạc, một giáo viên trẻ dạy Vật Lý của Trường THPT Nguyễn Du (quận 10, TP HCM) sáng tác và biểu diễn.

Màn biểu diễn đặc biệt của thầy được một học sinh đăng tải lên mạng với nhan đề: teach or rapper.

chào tất cả các bạn !
hôm nay mình lập topic này để các bạn cùng thảo luận về vấn đề lập trình cho 8051. cụ thể là 89xxx.
tuần này mình đang học môn thực hành vi xử lý, thầy giáo ho lập trình bằng ASM cho 89c52 để điều khiển các hiệu ứng led
ví dụ như hiệu ứng này:

Code:: anhthao:
mov p1,#11111110b
call delay
mov p1,#11111100b
call delay
mov p1,#11111000b
call delay
mov p1,#11110000b
call delay
mov p1,#11100000b
call delay
mov p1,#11000000b
call delay
mov p1,#10000000b
call delay
mov p1,#00000000b
call delay

jmp anhthao

delay:
mov r1,#120
delay1: mov r2,#50
delay2: mov r3,#10
delay3: djnz r3,delay3
djnz r2,delay2
djnz r1,delay1
ret
end

mình biết mỗi lệnh MOV, DELAY
lập trình hiệu ứng rất vất vả
bạn nào biết lệnh j hay chia sẻ với nha
rất mong các bạn ủng hộ và jup đỡ
