Install

Fetch required binary archive for your computer system and install the utility software to control the special features of the programmer.

Avrdude will be used to perform the actual programming once everything is setup.

tar Jxvf pololu-usb-avr-programmer-v2-1.1.0-linux-rpi.tar.xz
cd pololu-usb-avr-programmer-v2-1.1.0-linux-rpi
sudo ./install.sh

This utility only supports the Pololu USB AVR Programmer v2
(blue-colored, labeled "pgm04a").

MV should be a voltage in millivolts.  For example, "3400" means 3.4 V.

Usage

The programmer can either be used in ISP STK500 mode else as a serial UART for a bootloader.

Query a MEGA2560 connecter by ISP.

avrdude -B 5 -c avrisp2 -P `pavr2cmd --prog-port` -p m2560
