HI, I am new to this list and to PIC's. My question is about using the UART.
What I need to do it talk from a computer to a PIC, and give this PIC commands.
Then have the PIC respond to these commands back to the computer after the PIC
has preformed some simple tasks based on what info the computer sent to the PIC.


An example is A user wished to open a valve.  So user clicks a button in the
computer interface to open valve #1.  The actions that follow :  The PIC opens
the valve #1 and responds to the computer letting the user know that valve #1 is
open, it was unable to open valve #1 for some unknown reason.

Okay, now the question, can I do this? I have a book I am reading, and learning
about PIC's with. I have made a test board up (my own design). The problem is I
have never done this before and am not quite grasping what has to happen in the
PIC for this to work.

Next is there a simple bit of code that will interface the PIC to a PC.
I can get this kind of thing to work with if pin 1 goes hi open valve #1,

I am doing my testing on a PIC16F84
I also have a C compiler for the PIC, I am trying to use, it seems simpler then
Assembly and a little quicker for a newbie.

Thanks for any suggestions or help.
