Tiny AVR JTAG Programmer: Overview

With this small and inexpensive device, you can program any AVR that supports JTAG programming. The programmer connects to your computer through USB and is compatible with the open source AVRDUDE software.

Currently the programmer has been tested only with the ATmega1281 and ATmega169V, but the JTAG library is from the SP Duo programmer which has been tested with a wide range of AVRs.

I’m still working on custom hardware for the programmer, but a schematic is available and the circuit is simple enough to be hand wired or made on a breadboard.

The code is functional, but I need to spend a bit more time on the README file before releasing
