Willem,

Thanks for the USB related suggestion, but I've been "successfully" programming TinyScreen+ units on a Win 10 machine (circa 2019) for sometime now. 

Even though - schematically - the TinyZero is the same as the TinyScreen+ in terms of the processor, something else is going on and I don't think it's USB related.

I think the problem is on my end, but I can't be sure.

Again, any help is appreciated.

John

Hey John,

You are correct that the TinyScreen+ and TinyZero are pretty much the same schematically - so there shouldn't be a huge difference in being able to program them.

Do you see this same issue on every TinyZero? You said you had one that worked fine before?

You could try updating the Arduino IDE if it's not the most recent version to see if that makes any difference.

A small suggestion I am sure you are aware of, is to make sure you have "TinyZero" selected in the Tools menu when you are programming.

I hope that helps! Let me know if you find anything out!

Thanks,

Laveréna
