PICkit 2 as an AVR programmer

We have a Microchip PICkit 2 on the electronics bench. It lives in the cardboard tray at the woodstore end of the shelves, with the logic analyser. There should be two 12 cm programming cables with it - grey ribbon cable with black ends - 6 pin SIL M-F for Microchip PIC ICSP, and 6 pin SIL M to 3x2 F for Atmel AVR ISP, and also an 18 cm 6 pin SIL M to individual colour coded pins breadboard programming cable.

These are User:IanM's installation notes.

AVRDUDE support

Recent versions of AVRDUDE support Microchip PICkit 2 as an AVR ISP programmer. Use command line option: -p pickit2

Installation (Windows)

I assume you already have AVRDUDE, and possibly a GUI for it installed.

Run Zadig (from https://zadig.akeo.ie/ ) and do 'Options=>'List all devices'. Select the PICkit 2 and install the WinUSB (libusb) driver. If problems occur later return to this step and try the libusbK driver.

Alternatively (my preference) use libusb-win32 and install a filter driver for the PICkit 2 so both AVRDUDE and the PICkit software can use it. N.B. libusb-win32 v1.4 filter installer is broken on Win10+. Use Zadig to get libusb-win32 installed with the files in the right place, then device manager to revert to the OEM or Microsoft driver (without deleting any files), then reinstall the driver as a filter using libusb-win32 v1.4 filter installer.

Reverting to PICs

N.B. If not using a filter driver, to revert the PICkit 2 to the original USB HID driver for use with MPLAB or the PICkit 2 GUI or command line PIC programming utility you need to 'De-Zadig' the PICkit 2 by uninstalling it from Device Manager, selecting the option to delete all drivers, then scan for hardware changes to let windows reinstall it.

Arduino IDE Support

To add PICkit 2 as a programmer in the Arduino v1.8x IDE, append the following lines to "C:\Program Files (x86)\Arduino\hardware\arduino\avr\programmers.txt" after making a backup copy:

# User added PICkit 2
pickit2.name=PICkit 2
pickit2.communication=usb
pickit2.protocol=pickit2
pickit2.program.protocol=pickit2
pickit2.program.tool=avrdude
pickit2.program.extra_params=-v -V

Test the installation by selecting PICkit 2 as the programmer in the Arduino IDE and, with an AVR based board selected but no target connected, do 'Burn bootloader'. You should get a long and detailed report ending:

avrdude: MicroChip's PICkit2 Programmer firmware version 2.32.0
avrdude: initialization failed, rc=-2
         Double check connections and try again, or use -F to override
         this check.

Error while burning bootloader.

Connections to an AVR MCU

The PICkit 2 pin 1 is identified by a white arrow on the upper case.

Pin assignments are:
