My USBTinyISP is a BigPITA
Signs & Decorations March 7th, 2008I received my USBTinyISP AVR programmer kit from LadyAda.net / AdaFruit.com to program the AVR chip in the LED sign I’ve been working on. Here’s what I got:
There were all sorts of cool little thing-a-ma-whats-its inside:
I put all those parts in a pillow case, along with a spool of solder and my hot soldering iron and swung it around my head about 40 times. Here’s what I ended up with:
Here it is after putting it in it’s case:
I installed the software for it, and Windows detected it. It lights up all purty like when you plug it in, but I can’t get the damn thing to actually communicate with the AVR chip on the LED sign board. I keep getting an “initialization failed” error when I try to run “make install” from a dos prompt to actually write to the AVR chip.
I was up until about 2am last night messing with it. I’ll keep plugging away trying to figure out what the deal is and will report back here when I figure it out OR when I’ve smashed it back into tiny little bits with a sledgehammer.

Hi ladydada,
Thanks for commenting. I bought the kit from your site. The kit itself seems great, but I must be doing something wrong. I don’t really know what I’m doing. I’m going to try the different things I’ve seen about this same problem in your forums before posting there about it, in case it’s something that has a posted fix. I just checked the pinouts from the 6 pin connector on the programmer out to the correct pins on the AVR on peggy, and everything seems to be connected OK. I’ll post something on your site either way if I figure it out or not.
