Re: [avrdude-dev] Adding support for new programmer...

[Robert Connolly]

Hi Stan,

Thanks for your reply.

I found some directions here
(http://doswa.com/blog/2009/12/20/avrdude-58-with-ftdi-bitbang-patch-on-linux/) 
for ftdi chips, which I have been able to get to work.

I intend to write a blog post on the device this weekend, I'll post the
link when I have it.

Thanks for your help.

Cheers,

Rob
