print (bytes(buf).find(b'OK')) #test if buf contains a substring 'OK'

Note: bytes(buf) creates a copy of buf.

It can be done by modifying machine_pin.c. At line 312 the pin number is taken from the argument. That has to extended to compare against a string of known Pin names.I made a trial build by: a) extending the _pin_obj_t structure in modmachine.h to: typedef struct _pyb_pin_obj_t { mp_obj_base_t base;...

I simply call make in the ports/rp2 directory. By default there is a Makefile as wrapper to cmake.

Edit: I do not add any include "tusb.h". No need to fo so.

I can build that without any changes to scripts. So maybe you start over with: make clean and make I had that problem too initially, but that went away after Feb 12 with the. I cannot find the discussion I had about that any more. maybe related: https://github.com/micropython/micropython/pull/6791 h...

AFAIK, I had to deinit these submodules first and then update them again.

You have to update the submodules.

It should be possible, since one of the actions in _boot.py is creating the file system in flash with boot.py if required. The template for that boot.py is in the file inisetup.py, also located in modules.

Using the proper path separator is essential. Maybe you should put aside pycharm for a moment and use a simple terminal emulator like putty. Or use Thonny.
Without the proper file separator, Spielwiesen is not a directory, but just the part of a file name.

but sometimes all pins of one side from D27 to VP (d27 d26 d25 d33 d32 d35 d34 VN VP) show about 1v or 0,8v.
What's that?

Just floating pins in input mode.

In you C code, call:

mp_keyboard_interrupt();
