Just second guessing myself, so I before I modify my PCB....
If I want to use all default LCDOUT defines EXCEPT the standard PORTA data port....(I want to switch my 4 data lines from PORTA.0, A.1, A.2, A.3 over to PORTB.7,.6,.5,.4....?
Can i get away with this with the following code?
DEFINE LCD_BITS 4 'self explanitory
DEFINT LCD_DREG PORTB 'self explanitory
DEFINE LCD_DBIT 7 'working my way down B.7, B.6, B.5, B.4
'or will this hardware arrangment just not work as I am starting with bit 7 on portb with only 4 bit of data?
'should I be going the other direction....starting with bit 4 and going up to bit 7?
'second guessing stinks....
thanks for any help
