Some notes on using the Raspberry Pi Pico series.

Circuitpython
=============

The official documentation_ from adafruit is pretty comprehensive; these
are just quick notes with easy to copypaste frequently used commands.

I2C
---

There is no board.I2C(), to use i2c instead see the pinout_ diagram to
find a pair of pins with an available I2C port (I2C0 or I2C1, both
available on multiple pins) and then::

   import board
   import busio
   i2c0 = busio.I2C(scl=board.GP1, sda=board.GP0)

SPI
---

Like I2C, you can use any set of pins labelled SPI0 or SPI1 on the
pinout_ and then e.g.::

   import board
   import busio
   spi0 = busio.SPI(clock=board.GP2, MOSI=board.GP3, MISO=board.GP4)
