Adding Arduino Nano RP2040 Connect

[BlitzCityDIY]

New PR to fix local GitHub config issues and running pre-commit. Adding CircuitPython support for the Arduino Nano RP2040 Connect. Have tested all digital and analog I/O, I2C, onboard LSM6DSOX. Uses the AT25SF128A external flash.

LGTM; too bad about the confusing pin naming

[ladyada]

yeah its wierd because some analog pins are routed thru the esp32!

@elijahsgh Thanks for sharing! How do you use the wifi part of the code? TIA

@elijahsgh Thanks for sharing! How do you use the wifi part of the code? TIA

With the code I pasted above? You can't. That code was just me goofing around with the weird pin mappings that were being discussed. You can only blink lights with it. :)

To use the wifi part you'd need the full Adafruit esp32spi, etc.
