Im new to the PIC world and am having difficulties using it in my project. My project is a simple lighting control system. I already written the program (code). I programmed the PIC and build it on a breadboard. I also build a external RC ocillator. But I still get zero output.
PIN 19,20,21 - output from the pic to the keypad
PIN 27,28,29,30 - input to the pic from the keypad
PIN 23,24,25,26 - output from the pic, connected to the leds
PIN 1 - 5V pow
er supply
PIN 40 - GND
PIN 13, 14 - RC ocillator
Also, on pic16f877a, PIN 11,12 and 31,32 they both are VSS and VDD. So can we use only one of them or do we have to use both of them.
Can you guys help me PLEASE!!!
