What PIC are you using?
I am using PIC 16F877A,
i am doing project to control RGB led on the fan to display image,
i use 12 unit of shift register to save the port of the PIC, i use PCB to do it and now just realize that my RB0/int PORT ald in use,
other than RB0 can i use other port to run interrupt function or something similar like interrupt function?

PORTA suppose is a Analog to digital function, i've turn it to digital but seems like cannot control as input function, i curious what is the problem, hope someone help me, Thanks =)
