Having been ripped off by ARM's SEGGER debugger, this £12 unit is absolutely fantastic! It works brilliantly on most ARM based systems which support 3 wire debugging. One gripe is your site should have proper instructions on how to set up VSCode (or Eclipse) for debugging. See attached image (launch.json and environment variables). Maybe give example setups for Windows, MacOS and Linux under VSCode As for the probe itself, it's a game changer, allowing hobbyists to single step through code on microcontrollers (and the full blown Raspberry Pi). Utterly awesome!
