LCD problem

[Archangel]

Hi Andre, Try this, dunno if it will help, but worth a try,

main:
	LCDOUT $FE,$80
	LCDOUT "line 1              "
	LCDOUT $FE, $C0
	LCDOUT "line 2"
	PAUSE 1000
goto main

How do you have the OSC configed?
This might be a clue

Dave, I don't think that your link will help because the code show that the OP use MicroChip bootloader.

One day I should Try it myself

Main Problem is

DEFINE OSC 20

As far as I remember, Microchip Bootloader config fuses and code assume 48MHz BUT with a 20MHz crystal. So I would try

DEFINE OSC 48

Well at least I got the OSC 48 part.
Never used a boot loader though.

Do you set the configs the same as with out one?

[mister_e]

Most Bootloader I know, will ignore the config fuses in your code as they're already set in their firmware and don't have the ability to re-program them on the fly. HOWEVER, for many PIC18, you can do it later in your code. Darrel Already post something on that... BUT, using this, you will probably screw up most Bootloader... no free lunch

Bootloader are nice for firmware upgrade, but for development, they have their own limitations.

Thanks for the info.

Thanks guys
Changing to define osc 48 fixed all the problems, LCD serial everything. Now for the question -- Why???
On all the other projects you set the define to the cristal freq. but now you set almost 1.5 times higher.

I am confused can someone PLEASE explain this to me
