Have you ever used an Arduino Mega 2560 (or a similar board) and, at some point in the development process, experienced the LED mysteriously stopping to blink, garbled text being printed, or funny artifacts appearing in pictures? And all that without any apparent reason or any error or warning message? If you want to know what is behind it and how to solve this problem, read on.

Microchip recently lowered the price for its hardware debugger SNAP from more than €50 to less than ~~€20~~ €10. I have recently created the Python script dw-gdbserver for this and other hardware debuggers so that you can now use SNAP in the Arduino IDE 2 to debug classic ATtinys and small ATmegas. All in all, this is an affordable and care-free debugging solution for classic AVRs.

Arduino IDE 2 Meets dw-link

Debugging classic AVRs in the Arduino IDE 2 is finally possible! It took a while to implement this feature, but now it is just a piece of cake to enable debugging and start using the debugger.
