registers

Am I too bold if I suggest that you should lookin the datasheets and locate what examples there are from Keil and from the chip manufacturer?

The "hello world" of the embedded world is to blink a LED.

The next step up is to use a serial port. Obviously, you will be able to find _huge_ amounts of information about how to use a serial port. Why don't you look for that information instead of requesting that someone else does it for you?

If you do get stuck reading the datasheet or some of the available examples - feel free to come back and ask for help. But don't sidestep your side of the task. You must search. You must read. You must try to understand. If we post code here, you would not understand it anymore than you would understand the example code that gets installed with the compiler or that is available from the manufacturer.

And you will not be helped by code you do not understand!
