Hallo. I 'm developing a project on LPC1343 to acquire some data from a sensor, and then send the value through the USB to computer. What is the simplest way to do this? can i use the same usb cable for communications that i use to program and debug? or do i need to use the pins USB_DM, USB_DP?

The LPCXpresso's debug USB connection is dedicated to debug, you cannot use it for your own purposes.

You need to connect to the USB pins on the LPC1343 chip itself, by either adding you own hardware, or connecting to an Embedded Artists LPCXpresso baseboard.

I would suggest a good starting place for more information would be the two LPC1343 apps notes available from NXP's website:
