AN58726 is a continuation of basic-level AN57473. It describes additional features of the USB Human Interface Device (HID) protocol, including input and output transactions and composite devices, using PSoC® 3 and PSoC 5LP and the PSoC Creator™ USBFS Component. A variety of HID devices, including a keyboard with LEDs and a composite device, are used as examples. This application note is a prerequisite for the advanced-level AN56377 and AN82072.
Introduction
USB is a complex protocol, and it can be difficult for beginners to get a USB-based application up and running quickly. However, some aspects of USB are easy to use, especially the Human Interface Device (HID) protocol. HID is designed for common PC interface devices such as a keyboard or mouse, but it can be adapted for many custom applications. Most PC operating systems, including Windows, Mac, and Linux, include HID drivers. This means that you do not have to write a driver; instead, you can focus on developing your application firmware.
