DEFINE LCD_REBIT 6
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 7

But this won't work

DEFINE LCD_RSREG PORTC
DEFINE LCD_REBIT 1
DEFINE LCD_EREG PORTC
DEFINE LCD_EBIT 0

Any ideas?

Port C has analog features, try setting them to digital.

I don't understand why I can send out data on RC4-RC7 without setting to digital, but not E and RS on RC0 and RC1? I thought setting to digital was only needed for input on pin that was also A/D input.

Robert, you were right. Setting ANSEL and ANSELH fixed it. Thanks.
