I'm still working on getting the code onto the Trinket. It's ridiculous what I have tried to do and still failed. The most recent failure was using the GPIO on the Raspberry Pi to program Trinket over SPI. I don't know what I did wrong, but Avrdude wouldn't even connect...

So I have given up on that part for now, I will come back to it when I'm not so frustrated with it. I can continue prototyping the project with my $3 Chinese Arduino Nano clone for now, and when I figure out the transfer process, just put it all on the Trinket. I did get the OLED screen working without a hitch tho, so that's some good news.

So far this is my main gripe about theTrinket; no easy upload from the Arduino IDE. I futzed about with drivers, settings, baud rates, config files, SPI and more all to have nothing work. My Chinese hunk of junk that costs 60% less is plug and play, no hassle. I know it works, and I know it's something I'm doing wrong. But knowing these things does nothing for me but frustrate me even further. But whatevs, I'll figure it out if I have to use one of the Chinese clones as a programmer!!!
