I am having trouble with our assignment at microcontroller. We need to make a hardware using pic16f84a that enables a 3x4 keypad to enter 3 digits,that can be stored and retrieve if you want, then those digits will be displayed in 3 7segment display.
I really need help for this. I'm only a newbie in microcontroller so please help me. Any suggestions are very appreciated.
Oh by the way can I make the same pin of the pic to be the input and output as well? I mean for example, I will make the RB0 to be connected at the keypad and 7segment, is that possible?? Will I have problems if I will do that??
Thanks in advance for answering!
