AN58764 - Implementing a Virtual COM Port Using FX2LP™
AN58764 explains how to use a Cypress EZ-USB® FX2LP™ chip to implement the USB Communication Device Class (CDC). An FX2LP-based design can communicate with a PC as a standard COM (serial) device. This document contains example code with the required descriptors, code to handle class-specific requests, and the Windows information (INF) file required to enumerate the CDC device.
