    [SOLVED] need help coding pic16f84a scanning of switches

    hello i need help coding i want to produce an out put like this ive done some programming and changed the ports it runs on simulation but wont run in the circuit it cause my LEDs to turn off and on when i energize a single switch here the code ;RB0 controls RB7 and RA0 ;RB0=0 then RB4 and...
