A free/libre/open-source firmware library for STM32 microcontrollers.

A simple USB-JTAG interface implemented using LUFA library running AT90USB162 based on Open Hardware board opendous. Primary reason is to create a cheap replacement for the parallel port JTAG adapter ... [More] "Wiggler" and alike.
