hi all

thank you for your answers.

as i attached all of my files, i used a PIC16F877a (please first download my zip file.). probably there is no bug. i must define ADCON1.3:0 as DIGITAL I/O (not analog inputs) manually, thats all. so probably it is better that LCDOUT command automatically define ADCON1 register to save programmers time. (so my frind sayzer please don't insult to others.)

please accept my apologies if i incommode anyone, i only wanted PBP get better.

with best regards, sincerely, Mostafa
