@strg-v - zur info.
Anscheinend was geändert, habe gerade mit dem Pico2 getestet.

tl;dr

The GitHub issue discusses a hardware problem with the RP2350 microcontroller, where inputs on certain pins get "stuck" at a voltage around 2V due to an erratum (RP2350-E9). This affects the functioning of touchio and digital input handling. Developers are working on potential software fixes, like switching from pull-down to pull-up resistors, but hardware modifications may be needed for some designs. The issue impacts compatibility with existing hardware and Raspberry Pi Pico replacements.
