LPC2148 USB Audio DEVice Example
This USB example project implements an USB Audio DEVice that connects via the USB interface to the PC. It may be used on the following DEVices:
LPC2141
LPC2142
LPC2144
LPC2146
LPC2148
An USB Audio DEVice (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio DEVices can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board.
Refer to Running USBAudio for information on how to operate this example project.

I have build my own programmer. This DEVice can program the AT89C51 and works with it. So it can easily be adapted to programming other DEVices by itself.
The Atmel Flash DEVices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 DEVices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed DEVices if you must develop with EPROM DEVices (e.g. Phillips 87C751).
