I have a few microcontrollers sitting in my "junk parts" bin. I think some of them arrived there when, after programming them, they exhibited strange behavior. I've since learned a lot, for example, how having the wrong optimization on the compiler can cause such strange behavior. On the other hand, some of the microcontrollers may have well been damaged due to static, out of tolerance voltages, etc. Thus, I believe some may be in good working order.
Before I throw everything out, I wondered: Is there a relatively straightforward or easy way to test a microcontroller to determine if it is still good?
The micros in particular are the Atmel ATTiny13, ATTiny26, and ATTiny2313, both DIP and SOIC versions.
