AVR programming trick: Sharing target boards @ Evil Mad Scientist Laboratories

This week, Brad wrote in with an interesting question: Can you program the ATtiny25 on one of our ‘tiny2313 target boards? And the answer is yes: you can, with just a trivial modification.

Okay, back up– a little context here. The ATtiny25 and the ATtiny2313 are examples of AVR microcontrollers, the little brains that power many of our projects.

To program these chips, we use a usbtinyisp programmer, hooked up to a minimalist target board

  1. This article seems to be incomplete. Says, yes you can with a trivial mod, but doesn’t explain the mod. Is it the single green wire shown or is there more to it? Thanks!
