Fusebits (configuration bits) location

[dshay]

So it’s been 10 years since I’ve programmed Arduinos (AVRs)

I used to know exactly where to fine the boards.txt file when I needed to find fuse bits for when I purchased raw chips and were setting the configuration bits and then programming them.

I have the need to program ATMEGA328P for both 3.3V 8Mhz and 5V 16Mhz frequences and also ATMEGA32u4s. Any help on where to find this with IDE 2.x is much appreciated.

I really did try to find this information on the forum prior to posting.

See https://support.arduino.cc/hc/en-us/articles/4415103213714-Find-sketches-libraries-board-cores-and-other-files-on-your-computer#boards. You will find the needed files in a sub directory of the Arduino15 directory; on my windows system C:\Users\bugge\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6
