programming in LPC2148

It rather much seems that you are trying to avoid learning so that you can just hand-in someone else's work.

The way to actually learn would be by studying the documents already listed.

Here's a basic introduction to Keil's ARM MDK: http://www.keil.com/support/man/docs/gsac/

Then work trough some simple examples yourself:

1. Write some code to blink an LED connected to a pin.

http://www.keil.com/support/man/docs/uv4/uv4_examples.htm

2. Learn how to use the debugger to step through your simple LED code, look at your variables, etc

3. Learn to use the UART to transmit a fixed "Hello, World" string. Again, practice using the debugger with it.

4. Adapt your code to be able to send a variable string.
This will be invaluable for future work - particularly, to send messages to a terminal so that you can see what your code is doing.
Keep practising with that debugger...

5. Adapt your code to be able to receive on the UART.
This is a good basis for learning how to react to events coming from the hardware.

6. Now study the documentation for your chips Timers. Use a Timer to blink the LED at a fixed rate

7. Now study the documentation for your chips PWM features. Use that to blink the LED with variable duty cycle

You're done!

I guess you could skip straight from 2 to 6 to meet your immediate deadline, but being able to use the UART is really such a basic skill that you should not skimp on it...

thank you.....i will follow your words...and soon i will get it...
