I tried to advance beyond a simple LED blink test with RP2040 and I run into problems with a mishmash of different environments, legacy libraries and ambiguous terms: Arduino, Mbed, etc. They may be obvious to old timers. For me, they required some archeological digs to uncover their history, and it’s still not clear how to deal with them. I don’t care about Arduino sketches, the standard C/C++ main()
is fine. I’m fine with loosing access to some Arduino libraries, allegedly there is a shim to adapt a large fraction of them.
Is there a direct support of Raspberry Pi Pico C/C++ SDK? Is this
framework = arduino
my only option?
