chipKIT Tutorial 2: Serial communication with PC

The PIC32 processor on the chipKIT Uno32 board provides two hardware serial ports. One of these is used by the on-board FTDI chip to create an USB-UART interface that allows the MPIDE tool running on the PC to communicate with the Uno32 board through an USB port. In this tutorial, we will use the same USB-UART interface to demonstrate a two-way asynchronous serial communication between the Uno32 and the PC. The Uno32 board receives a serial command through the PC’s USB port to turn an external LED on and off. In return, the Uno32 board acknowledges to the PC by sending the new state of the LED.
