Unfortunately, the first time I tried to use it with avrdude, I got this error warning: avrdude: warning: cannot set sck period. And it works 🙂 The 6-pin end is marked with whiteout on pin 1 as is my custom. But it was in keeping with the cheap programmer. That’s not a great idea, since the insulation displacement clips in those connectors are really designed for one-time use.

My programmer came with a 10 pin cable, and I think I cut one end off and reused the connector for the 10-to-6 pin adapter cable that lives in the programmer now. Warning: this pinout doesn’t work with this programmer! See update below. The author suggested using little scraps of wire to fill in the unused positions in the 10 pin header, which seems to work well. But it turns out there’s a really nice Inventable on making such a cable, complete with an excellent picture that tells just about everything you need to know. The pinouts of the two connectors are readily available. Everything I have – including Tiny85 boards – is 6 pin. Unfortunately, it had the ‘other’ Atmel standard programming cable – the 10 pin version. I felt no need for a dedicated programmer.īut when I ran across a USBASP knockoff on Ebay for $2.29 (and of course free shipping) I couldn’t resist. There’s always an Arduino around, it works, and it’s essentially free. I’ve been using the Arduino ISP programmer sketch, an Arduino, and one of my mini shield cables as my AVR programmer for a couple of years now, and that’s been pretty satisfactory.
