im using a pc1602aru-h lcd with a pic18f2431
ive coded my pic with
Code:
define osc 20
Define lcd_dreg portc
define lcd_dbit 4
define lcd_rsreg portc
define lcd_rsbit 0
Define lcd_ereg portb
define lcd_ebit 3
define lcd_bits 4
define lcd_lines 2
define LCD_commandus 1500
define lcd_dataus 44
pause 1000
main:
lcdout $FE,1,"hello"
lcdout $FE,$C0,"world"
pause 1000
goto main
end
there is probably something wrong with my code... but however it doesnt stop the fact that im getting abolsutely nothing coming up on my lcd. its stays as blank as it ever has been.
im pretty sure all my wiring is correct and ive checked there is 5 volts across vss and vdd. anyone help me with this one? dont worry ive checked pretty much every thread i could find on this but to no avail
thanks
