I've noticed that the ATtiny1614 can also read touch sensors with no external components. The idea is to connect a piece of metal (possibly isolated to protect against ESD) with one of the MCU pins and simply touch it with your finger to trigger an input. Unfortunately I wasn't able to find out how to use this. The main datasheet doesn't say much about this and just refers to Atmel Start. There is an example for a different model only which I could download and open in Atmel Studio. It contains tons of code (compiling to 7 kB binary size) and also custom static library files for the tiny817 which probably won't work on my hardware.
In one of the files in the project, there was a link to another PDF document that tries to explain how to use all of this. Again, it reads like it's infinitely complicated to get this up and running. When I create a new project in Atmel Start, for my model, with one touch button, and try to export it, it simply fails with no reason ("failed generating the project"). Seems like that wizard won't help me.
So I'm looking for the simplest possible example to drive a single self-capacitance touch button with minimal code. Can anybody please help me with that? The web doesn't offer me anything about this. For now, I'm not interested in any of the fancy 2D slider or proximity stuff the docs talk about. And if that requires another year of studying, I can live without it.
