Using UART in PSoC1
How to implement a UART in PSoC1?
For the implementation of UART, two communication digital blocks are required. PSoC Designer provides an 8-bit UART UM with a set of APIs for data communication.
Attached document and project provides an example of how to configure UART for a particular baud rate. It also shows how to handle the transmission and reception of data via UART on both PC and device side.
