Well pooh … The tiny85 won’t work for what I want to do with this year’s xmas display, so I thought I’d jump up to the tiny84 for it has 14 pins. Except, STK500 doesn’t support the 84, but it does the 85 - what gives?! I have to use ArduinoISP to program them. One step forward, 2 steps back. Time to permanently dedicate a rig for that …
Shoot me a data sheet for the 84 and I can see about giving you builds to tweak/try for your display this year.
