LCDOUT with 16f684

[mister_e]

be sure your r/w pin (pin 5) on LCD is ground. Is when you're increase voltage on Vo (pin 3, kind of contrast) you see some black square block?

by the way PORTC is only 6 bits.... so you must you this define


; Set starting Data BIT (0 OR 4) IF 4-BIT bus
DEFINE LCD_DBIT 2 ;instead of 4

but not sure if it's gonna work

May use
DEFINE LCD_DBIT 0



do you use internal or external clock. In case you use internal clock you have to define OSCCON for proper clock mode.... factory is 32khz...really slow

datasheet p31 (pdf)

OSCCON=$60 ;set to internal 4MHZ clock

that will work now!!!
