Hi,
I have a very old ISP programmer (Called "Asix Presto") which I am trying to add to the IDE. It doesn't use Avrdude or any of the protocols I can see in programmers.txt. I can export the compiled binary and plug it into the programmer's CLI and that works fine but I would still like to add it to the IDE. I guess there must be a file somewhere which defines the command line for a given programmer but I haven't been able to find any info. Can anyone help?
