I am not so sure that you have research much...... I wanna see that T-shirt :wink: ..... There is plenty of info about that on the web. Google returns all you need in a search for "LCD PIC routine asm"

Not to mention Microchip pages show some **broken link removed**.

Some points to looks for:
* Know how the LCD works
* How to send commands
* How to send characters
* ASCII table

If you had PICBASIC PRO it would be as easy as :

LCDOUT $FE, 1, “nothing better to do ”

Good Luck

Have a look at this website, it seems to describe in depth what you are trying to do, with a PIC 16C84:
