PIC32Prog programs PIC32 controllers via a number of back-ends on a variety of platforms.

The version of PIC32Prog available from GitHub is compatible with Nanu Nanu at 115200 and 57600 baud.

apt-get install libusb-dev libusb-1.0-0-dev libudev-dev
git clone https://github.com/sergev/pic32prog.git
cd pic32prog
make
make install

In this example we program the Ape65 MX150 firmware with a Nano 3.0 clone running Nanu Nanu (see photo).
