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 …
