Provides access to onboard sensors and battery charge management circuitry
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.
Make sure that you have circup installed in your Python environment.
Install it with the following command if necessary:
pip3 install circupWith circup installed and your CircuitPython device connected use the
following command to install:
circup install seeed_xiao_nrf52840Or the following command to update an existing version:
circup updateimport array
