Raspberry Pi Pico¶
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)
