Cypress - AN56377 - USB Vendor Commands with PSoC®︎ 3

Introduction

The USB interface on PSoC 3 can be used to control PSoC 3 based products or monitor fast changing variables, both from a host computer. The example project discussed in this application note implements these functions using USB vendor requests through the USBFS component of PSoC 3. This provides the ability to easily log and display data obtained by manipulating the other components in a design.
