This application note explains how to implement a full-featured USB-to-UART bridge using PSoC® 1. It also discusses user module configuration, critical firmware, and reasons why a USB-to-UART bridge is needed. A step-by-step USB-to- UART bridge implementation is given for better understanding.

简介

Although USB is now the generally accepted standard for interfacing with PCs, RS-232 and other UART protocols are still widely used in embedded systems and some PC software. This application note describes a USB-to-UART bridge solution implemented in PSoC 1. This solution is designed as a reference for designers who need such a bridge in their systems. It can be implemented and tested on a CY3214 USB Evaluation Board.
