If you want a standard serial type communication then you can look at something like a CDC class driver. You can find a little information on this here: http://www.freertos.org/LPC1768_CrossWorks.html look under the "Functionality" section (it is for a different processor, but it may be compatible as it is also an LPC device).

Look at "gadget" which is a set of device-side drivers for functions such as serial over USB, "ethernet" over USB, mass storage over USB, etc, _AND_ corresponding host drivers for windows and linux PC's to talk to your device. Most embedded linux/uClinux devices with device-side USB "gadget", or else something along similar lines. |
