You may prefer to create your folder for avrdude somewhere else but for ease, I created the folder:Īnd into it, I extracted from the zip folder: I used version 6.3 for windows, named: avrdude-6. It is installed as part of your Arduino installation but we want to amend its default configuration specially for use with the new chips and the jtag2updi tool, so we'll install a separate instance somewhere that we can customise it. This tool is used for uploading files to chips and reading memory from chips too. I used the Windows installer (not the Windows App Store version) but it probably doesn't make any difference. Atmel Studio (I used version 7) with ATtiny Device Pack (I used version 1.3.229)Īvailable from.avrdude (may be optional - I used version 6.3).In summary, we are going to use the following collection of software tools: Once it's set up, it is much less hassle than the explanation below may give you the impression that it is! This might seem like a long-winded explanation but I wanted to include details that might help people that aren't confidently doing this sort of thing frequently. I decided this might be better as a log, which I can then reference from the instructions.
