Instructions state to set “i2c_bus: i2c1a”. However, instructions for pin connections set the device up to use i2c0a (earlier in the page under line “Recommended connection scheme for I2C(i2c0a) on the RP2040:”. I ordered a new accelerometer before I figured out what the problem was. Once I configured the pin to use i2c0a, it works perfectly. It’s probably obvious to veterans, but it can easily stump beginners like me.
