hi,
i have been experimenting on pic over a few days already. everthing works 100% over the mplab simulator (6.5). i am burning the chip using jdm programmer and ic-prog version 1.05. btw, my chip is 16f84a.
everthing works 100% in the simulator, however, things don't go well in hardware.
i am trying to spin 2 stepper motors using port b (one nibble each). the stepping works perfectly in rb0, rb1, rb2, and rb3. while there is absolutely no stepping action in rb4, rb5, rb6, and rb67. :shock:
the logic probe pulses on the low nibble, while it stays high on the high nibble.
i made another program to test if portb is damaged. unfortunately, every pin of portb is fully functional.
i don't know what on earth is wrong with the program i made because it works the way i wanted it to be in the simulator, but it never works on hardware.... :evil:
