Detailed Description

Initialise the TCA9548A chip at address with i2c_driver.

Parameters

address	The I2C address to use for the device. If not provided, the default address is used.
i2c_driver	An existing i2c driver object. If not provided a driver object is created.

Returns

Bool Constructor Initialization True- Successful False- Issue loading I2C driver

Constructor & Destructor Documentation

__init__()

def qwiic_tca9548a.QwiicTCA9548A.__init__	(		self,
			address = None,
			debug = None,
			i2c_driver = None
	)

This method initializes the class object.

If no 'address' or 'i2c_driver' are inputed or 'None' is specified, the method will use the defaults.

Parameters

address	The I2C address to use for the device. If not provided, the method will default to the first address in the 'available_addresses' list. Default = 0x29
debug	Designated whether or not to print debug statements. 0- Don't print debug statements 1- Print debug statements
i2c_driver	An existing i2c driver object. If not provided a driver object is created from the 'qwiic_i2c' I2C driver of the SparkFun Qwiic library.

disable_all()

def qwiic_tca9548a.QwiicTCA9548A.disable_all

(

self

)

This method disables the connection of all channels on the Qwiic Mux.

disable_channels()

def qwiic_tca9548a.QwiicTCA9548A.disable_channels	(		self,
