Arduino IDE Reference Addendum?

Development Boards Raspberry Pi
1

I use the Arduino IDE Reference links often while programming my Sparkfun Pro Micro. Recently I started to program on a Sparkfun Pro Micro Pico RP2040 which has two cores, multiple UARTs, multiple I2C, plus built in flash. Is there an addendum to the Reference pages that tells me such things as what C++ command lets me assess the second core, second UART, or how to store data on the flash external to the RP2040 device?

I’ve picked up bits and pieces from YouTube videos but a central location would be so much better.

Thanks,

Our hookup guide has a link to the SDK’s PDF that covers most everything :smiley:

The hookup guide has a lot of basic information and then jumps into hardware register level. Where does it mention, for example, accessing the second core using setup1()?

There’s a short example code snippet on page 16 of that PDF I mentioned, https://datasheets.raspberrypi.org/pico/sdk/pico_python_sdk.pdf

This is python, not C++.
