hello,
i want to ask anyone who's know about lcd program, when i use lcd 16x2 with this routine program its appear in lcd. this is a routine for 16x2: -----------------------------------------------
startup: mov a,#38h
acall comnwrt
acall delay
mov a,#0eh
mov a,#01h
ret
comnwrt: mov output,a
clr rs
clr rw
setb e
clr e
datawrt: mov p1,a
setb rs
---------------------------------------------------
anyone who's know how to change this program to lcd 20x2, because i use 20x2 lcd, i can do the 16x2 lcd program but not 20x2..
or maybe the program its same? because my problem, the character doesn't appear in a second line..
what can i do? please help me..
but we nothing about your 20X2 LCD. Did you read the datasheet? Do you know how it works, any why this code does not?
