F_CPU not defined for Arduino Nano RP2040 Connect

Therefore there is an error when compiling.
The authors of the RP2040 core try to justify the lack. It's just ridiculous!

Hi,

nice to hear the library got tested on the RP2040 too. No time spend with that board .

What could be added to the library is something like

#if !defined(F_CPU)
#ifdef ARDUINO_ARCH_RP2040
#define F_CPU 100000000     // ???
#else 
#error "need to define F_CPU"
#endif

However I think that should be solved in the "Arduino.h" somewhere.

opinion?

Yes, I am using this extension and it works.
I was looking for this library because it works on my 3 wifi enabled controllers!
These are Nano 33 IOT, Nano RP2040 and the ESP family.

Good to hear the lib works on those different platforms. I mainly tested UNO and ESP32.

Had some thoughts about fixing this issue in the lib but it should be fixed in Arduino.h (or one of its dependencies).
So for now I am not going to add it to the library.
