Imp powered in-system programmer for AVR MCUs

This has taken me quite a while so I hope at least some people find it useful :slight_smile:

I’ve seen a few Imp powered bootloader based programmers for AVR MCUs.

But I wanted a full featured in-system programmer so I came up with this…

All the code is available on GitHub and I’ve put together a way over long blog write-up of the whole thing here:

Please don’t be put off by the length of the post - the actual setup and usage is really very simple.

I’ve attached a way impressive animated GIF showing an ATtiny85 that has just been programmed by an Imp to flash an LED :slight_smile:

Programmers have come up a couple of times on the forums before with people like @aron, @generjones and @hugo.

Would be interested to hear what you and others think - hope’s it’s fun/useful.
