Programming the ATTINY85-20SUR

This post ties together my two previous posts, “ATtiny85 SOIC chip Program Adapter” and “Universal programmer dusted off“. I inserted the ATTINY85-20SUR nested in the SOIC Adapter Socket OTS-20-1.27-01,  plugged it into my DIY Universal Programmer socket and connected it up to my USBasp programmer. … Continue reading
