README.md

This is the firmware for the TNC3 version 2.1.1 hardware.

Building

Use Eclipse with CDT and the GNU MCU Eclipse plugins.

Debugging

Logging is enabled in debug builds and is output via ITM (SWO). The firmware is distributed with an openocd stlink config file that enables ITM output to a named pipe -- swv.

To read from this pipe, open a terminal and run:

while true; do tr -d '\01' < swv; done

If you change the MCU's core clock, you need to adjust the timing in the stlink-tnc3.cfg config file.
