EZ-USB® FX3 USB Debug Example

Last Updated:

This example illustrates the use of the FX3 firmware APIs to implement a debug log mechanism over the USB interface.

The device enumerates as a vendor specific USB device with a single interrupt endpoint (EP1-IN). The application sends out periodic log information out on the USB interface. The length of log can be up to 128 byte. So the user should never request for data transfer of size less than 128 byte.

Note: Pre-built binaries are provided in the Release and Debug folders in the zip file. FX3 SDK should be installed in the system to rebuild the example project with any modifications made.
