what is the bit instruction to get to LCD line2

[EDWARD]

How do i get the cursor down to the 2nd line?

i have a 2 line lcd that im using in 4 bit mode. i cant seem to diplay any data on the lower half of the screen (line 2).

i have looked all over but can only find the home command to be the closest thing.( which takes the cursor to line 1 cell 1)

i cant use any of the lcdout feature cause my pcb is wired weird. I need the actually byte command sent to the instruction registers on the LCD.


have i over looked something? because if i just keep displaying on the top line it doesnt "Wrap" the text down to line 2.

BTW, i got almost all of my project done, just wanted to say thanks for all the help so far.

The Manual !!!!

with LCDOUT $FE,$C0 so i guess your routine must send only $C0 to the LCD... OR the same way when you do the LCD initialisation at start-up time.

Hello Edward,

If I am correct, were you not working on your own LCD routine??

If so, Treat it exactly like the LCDout....

Send a $FE, then a $C0 (if you have a routine) like the one I posted...
If not, turn on your Command/Data pin to Command, and write a $CO.

i havent tried it yet but i think you are correct. yes dwayne i im doing "custom" lcd routines, great memory my man.

thats why i cant use the lcdout function.

what manual? i have the hd44780 commands sheet, i was having trouble interprting what the command actualy did, i also went to like 5 different webpages i found listed through out this forum to try and find a laymans description of what setting the dd reisters and stuff actually does.

>> what manual?

All the valid LCD I/O commands (certainly the cursor line-locating commands) are in the PICBasic manual that came with your PBP software (also available from the MeLabs website).
