Project 8: PC Interface Using the USART
Communicating with the serial port on a PC is a very useful tool. Applications include
a piece of test equipment that needs to interface to a PC or a design that uses the serial
port during development to configure the device. In this project, the PIC16F917 will use
the USART to receive commands from a PC application. Another notable feature to this
project is that the firmware implements an auto-baud routine to sync up with the
application.
