Microchip recently lowered the price for its hardware debugger SNAP from more than €50 to less than €20. 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.

… to screw in a lightbulb? The correct answer to this question is: “None, this is a hardware problem!” But then, this is not the right question! The right question is: “How many ISP programmers do you need to burn a program into flash memory?”

One of the most confusing things, in particular for newcomers, are the AVR fuses. Worse, by setting the wrong fuse bits, you can “brick” your MCU, i.e., a normal ISP-programmer cannot talk to the MCU anymore. In this blog post, we will present tools that help you to set the fuse bits right. And if push comes to shove, that is the wrong fuses have been burnt, I tell you how to recover …
Avrdude is the workhorse for programming AVR chips from Atmel (now Microchip). It works flawlessly on all platforms with a huge number of different programmers. There are a few exceptions, though. The Atmel-ICE, a very decent programmer and debugger, could not be used under macOS (>10.13). But finally there seems to be light …
