I am very new to AVR, so please be gentle. I will try very hard not to waste your time.
I am designing a project around the new ATtiny817 (I know it is new and not in production yet).
I have purchased a couple of the 817 XPlained boards from Digikey and development is going slowly but well.
I was about to buy an Atmel ICE programmer to UPDI (single wire) program the new chips but it occurred to me.
Could I make a programmer by taking a $9 817 XPlained board, desolder the 817 chip, hook the PA0 pin (UPDI/Reset), power and ground to a connector?
To me this would seem to be cheap and easy way to make a UPDI programmer that would have the connector style I want.
This would also give me a test 817 chip to solder to my PCB.
