    PIC 16F877A output_b() problem

    Hi... Well.. I need to use the output_b(value), where value is an 8bit integer (0-255). This should set all the pins on port B either high or low depending on the integer value. The problem is that no matter what value (between 0 & 255) the RB3/PGM pin is always low. So if I enter...

    PIC 16F877A output_b() problem

    Hi all, I am having some issues with the output_b() function. I program the PIC 16F877A with output_b(255) which should put all port b pins on high level. I tried 3 different PIC 16f877A and all of them had B3/PGM at low level. I also tried the set_tris_b(0x00) before the output_b() method...
