Hi Steve,
PortA.4 has open drain output, I believe will require external pullup resistor.

Problem solved.... it work!!!

first i forgot to define ADCON1 = 7 and the pull-up resistor
on A4 (open drain) (thanks to Mat and Joe)

Then another error found was on

DEFINE LCD_DBIT 4

instead of

DEFINE LCD_DBIT 0

Thanks for help......

Steve
