I2C read: Master stops sending clock
Here's a small update: I've replaced my I2C functions with the code from the Arduino Wire library (a C++ class). A few minor tweaks were necessary to make it compile. With this...

I2C read: Master stops sending clock
That's exactly what I started with. IIRC it was published somewhere in this forum with no positive or negative feedback. I can't see any difference between the operations and...

ATtiny1614: EEPROM read/write in C
Now that's a lot of additional questions. I only have one. And if somebody has ever done EEPROM access on a 1-series device with C code, I'd be interested in snippets of it.

UPDI speed
I have to correct my numbers. After counting the seconds more carefully, the smaller 4k program takes 20 seconds and the larger 8k program takes 40 seconds to flash.   So if...

Simple example for touch sensors
I know that sample. But it's far from simple. And not for the hardware I have. That code generator has failed to do something for my hardware so I can't make any use of it.
