adafruit_tca9548a

CircuitPython driver for the TCA9548A I2C Multiplexer.

• Author(s): Carter Nelson

Implementation Notes

Hardware:

• TCA9548A I2C Multiplexer (Product ID: 2717)

Software and Dependencies:

• Adafruit CircuitPython firmware for the supported boards: https://circuitpython.org/downloads

• Adafruit’s Bus Device library: https://github.com/adafruit/Adafruit_CircuitPython_BusDevice

class adafruit_tca9548a.TCA9548A_Channel(tca: TCA9548A, channel: int)

Helper class to represent an output channel on the TCA9548A and take care of the necessary I2C commands for channel switching. This class needs to behave like an I2CDevice.

try_lock() → bool

Pass through for try_lock.

unlock() → bool

Pass through for unlock.

readfrom_into(address: int, buffer: array | bytearray | bytes | memoryview | rgbmatrix.RGBMatrix | ulab.numpy.ndarray, **kwargs)

Pass through for readfrom_into.

writeto(address: int, buffer: array | bytearray | memoryview | rgbmatrix.RGBMatrix | ulab.numpy.ndarray, **kwargs)

Pass through for writeto.

writeto_then_readfrom(address: int, buffer_out: array | bytearray | memoryview | rgbmatrix.RGBMatrix | ulab.numpy.ndarray, buffer_in: array | bytearray | bytes | memoryview | rgbmatrix.RGBMatrix | ulab.numpy.ndarray, **kwargs)

Pass through for writeto_then_readfrom.

scan() → List[int]

Perform an I2C Device Scan
