UART help(LPC1114)

There is a book that I think would be belpfull by YIU called the
Definitive Guide to the ARM Cortex M0. Even if you do not want to
buy the book, if you search for the book and find the book home page
of the publisher you should be able to download the example projects
for no charge.

store.elsevier.com/product.jsp

there are online companion materials that you can download there.

This book targets LPC1114 Keil board.

I think the text_io might be instructive to look at.

Also, I would try just using Tera Term progam to talk with the board instead of
writing a C program. At least to get the MCU program correct.

Also, I do not see any example there that uses interrupt for the UART.

I also like to look at the Measure example for a Cortex M3 at the following
location:

C:\Keil_v5\ARM\Examples\Measure

Although I has a lot of things going on at the same time.

I'll definitley check the book out. Thanks a lot Cpt. Vince your post really gave me a lot of insight on what I'm supposed to do. I don't know why I didn't think about doing it that way in the first place. Thanks!

Olson, an issue I'm running into is how to trigger the UART interrupt loop that I posted.

I'm glad I was able to help you realize and refine what you need to learn to implement your goal.

Back in the day, I didn't know what I was doing either.

I had searched high and low to find a "pull-up resistor" because I thought it was a different component than a regular resistor.

Eventually, I asked an engineer and he explained it. I felt like an idiot.
Feeling like an idiot is better than not asking at all.

Feeling like an idiot is better than not asking at all.

Unfortunately there are too many who don't do this, thinking it's better to become a consultant.

Some people ask - but lots of people gravely fails to supply enough information that anyone can answer. And the (often total) lack of information in the questions indicates the lack of thought spent before asking the questions.

So very few questions are bad questions (unless they are constantly repeated). But the way the questions are asked tends to quickly separate the fools from people who wants to learn.

You can take a look at the examples provided by NXP

Forgot to say the USART example uses Interrupt
