hi, my task was to get this display up and running and to put out one letter. i have written the code in assembler. i am having problems setting up the display. i want to put out the letter n. the code i wrote is below:
org 0000H
mov a, #38h
mov dptr, #8000h
movx @ dptr, a
acall delay
mov a, #0eh
movx @ dptr, a
acall delay
mov a, #01h
movx @ dptr, a
acall delay
mov dptr, #8010h
disp: mov a, #04eh
delay: mov r4, #255
here: djnz r4, here
ret
end
anyone got any pointers or see a fault?
