PIC18F1320 Project

[Waterboy550]

I'm starting to use micro controllers for the first time and have some questions about how to use my controller. I'm using a PIC18F1320. Here is the Pin Diagram for the PIC. Were are the I/O for this controller and where are the power and ground connections? Thanks for any help.

RA0-RA3, RB0-RB7 are your I/O pins, there are many configurations you can choose for what kind of I/O you want, refer to your datasheet: https://www.electro-tech-online.com/custompdfs/2010/04/39605F.pdf
Vss is your ground
Vdd is your power (+5V)

I'm trying to do something that sends and receives information to and from a PC via an RS232 connection. Would I be able to use any of these I/Os or do only some of them qualify? Thanks for the fast response.

Take a look at the datasheet I linked, chapter 10 is clearly marked as I/O Ports and has everything you need to know about PIC I/O on that chip. Think all of them can be used as digital I/O. That chip even has EUSART which might make your serial comms even easier, chapter 16.

It looks like you dont know what you are working with, heres a free book from Mikroe, its for a 16F84 but will give you an idea of what a PIC is, the rules as far as hardware is concerned are nearly same(but do look the datasheet for functions).

hi fellow noob.
i am amazed no one has given you the "start with flashing a LED talk", its what most of us noobs are told. and to be honest its good advice, learn to light a led at will on any given pin then learn to flash it, connect a few leds to diff pins and flash in sequence, then learn to make nice patterns with leds once you get that far (dosnt take that long) add a switch and get a led to light when you press it..
all this seems pointless waste of time and energy, well thats what i thought at first but once you learn to flash leds ect then you get a better understanding of the datasheet and I/O operations and tristates of ports (high/low/input). start slowly and build up to rs232 ops, without the basics its a up hill strugle i can verify this from experiance. good luck with the project
