Adafruit CircuitPython BusDevice¶
SPIDevice helper classes make managing transaction state
on a bus easy. For example, they manage locking the bus to prevent other
concurrent access. For SPI devices, it manages the chip select and protocol
changes such as mode. For I2C, it manages the device address.
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-busdevice
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-busdevice
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-busdevice
See examples/read_register_i2c.py and examples/read_register_spi.py for examples of the module’s usage.
