Hiya guy's,
I'm having a heap of trouble working out how to define portB pins 4-7 as lcd data lines. I'm using Nigel's tutorial the 16 bit counter one for testing it out. Now when i use rb0-4 as the data it works fine but for the life of me no matter what I try all I get is blocks on the first line. The main reason I want to use the higher pins for the data is I want rb0 free to use for the interrupt feature. I'm using the 16f876a with a bootloader so changing the code is a breeze. I'll really appreciate some help with this.
Cheers Bryan
