lpc2148 and USB communication

[supi]

I want to develop a system s.t lpc2148 will sense signal from its on-chip ADC. Data from ADC will be stored in memory of lpc2148 and will be transferred to PC through USB communication.
I am trying to write code for it. I am referring code from keil library for memory device. But still i am stuck.
I have written program for initialization of lpc2148 and it's working.
I have written descriptors also for my device.
But now not getting how to approach. Can anyone help?

Thanks!

Hi

The easy way to the task is to use the CDC library

since it is working directly with windows terminal program

First search for a CDC source code for the LPC2148 (first try NXP site or Google )
Then search for ADC code using interrupt (try the YAHOO LPC21xx group)

Build a software that use both of this code

All the best
