The NU32v2 has the ability to talk directly with a computer over a virtual serial port connection. This ability can be used to debug code, transfer data, and interact with the microcontroller using a computer.

Overview

The NU32v2 uses an on board FT233RL chip from FTDI to convert RS-232 serial communication to USB. Using drivers from FTDI, the communication can be opened by any program that can access a serial port. On the NU32v2 side, sample code has been created to enable the Serial module on the PIC32. Using this code you can write strings to the computer, and generate an interrupt when characters are received. On the computer side, several programs that can access the serial connection are discussed, including PuTTY, Processing and MATLAB.
