This wouldn't normally be worth mentioning.

But it's an ATtiny28, which only implements a rather archaic version of High Voltage Parallel programming.

And my STK500 doesn't seem to be working.

So first I had to build a high voltage parallel programmer.

And implement firmware that would talk to something, because I sure can't tell how to get AVRDude to talk to something that implements HVPP :-(

 

In the process, I seem to have erased the signatures from two of my Tiny28s.  Which is "interesting", since they otherwise still program fine and run the blinky code.

This is a bit like announcing you just had a successful drive down to the local shops ... but first you had to build an engine+car !!

 

Well done.

Some learning curves are steeper than others!
