you first need to add an LCD module and then.. do step by step execution, it will show you the commands you send etc.. it help you analyze the programming is ok or not.

what shall i write in the configuration box?
and i am using a special header for lcd, hope that is not a problem.
it is in 4-bit mode.
pls help its urgent.

well.. download the all in one LCD library as example for LCD. configure the port you are going to use..
after that...
when you debug...
1. right click and add LCD.
2. select the make.. simple to select
3. set the ports you are using.. in the boxes.. set them as.. D:0x... some number the port you are using for LCD. e.g if you are using P0 then you can set as. D:0x80 etc.
there is a yellow '?' button is there.. to help you out.
4. start debugging.

Note: it has only 4-bit interface.. not 8-bit
hope this helps you

pls chk the sample program........is it ok?
Mon Jul 02 2007, 06:00 PM
actually it will be better if you write program in your own way. i give you steps..!
send first init value - 0x30
send second init value - 0x30
send third init value - 0x30
Set the data width - 0x20
then send function set - 0x28
after that other commands.

after that it will give you the desired results just want to say.. check coding

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
