I have tried some code but I cannot understand why I am getting the results I seem to be getting.
If I:-
mov dptr,#TABLE
it gets me to the top of the table.
Not really what I want.
So I have a value in the the acc.
First save it then:-
loop:
MOVC A,@A+DPTR 'get a character
JZ exit 'jump if acc 0 to exit
LCALL WRITE_TEXT 'write it to the port
INC DPTR 'get next char
CLR A 'clear acc for next character
SJMP loop 'loop back to get a character
Thats how I think it should work but the LCD display seems to run away at great speed, show garbage and what ever.
The table looks like this:-
table:
DB "TX1240.0",0h
DB "TX1240.5",0h
DB "TX1241.0",0h
DB "TX1241.5",0h
DB "TX1242.0",0h
DB "TX1242.5",0h
DB "TX1243.0",0h
DB "TX1243.5",0h
DB "TX1244.0",0h
and so on...
I have read the instruction set but now i'm stuck???
If I had some code that works at least I could try it and understand why it is hapening:)
From the very unchilled...
