L", and connect them to the corresponding pins on the I2C chips.
   See the <a href="PicoPinout.htm">Pico pinout diagram</a> for a list of the
   ports that can be designed in the SDA and SCL roles.  Pay close attention
   to the way that some pins are labeled "I2C0" and others are "I2C1".  These
   refer to the two separate I2C controller units on the Pico.  You have to
   pick an SDA/SCL pair that's on the same unit - so if you select an
   I2C0 SDA pin, you must pair it with an I2C0 SCL pin.
