API Reference

qwiic_gpio

Python module for the Qwiic GPIO.

This python package is a port of the existing [SparkFun GPIO Arduino Library](https://github.com/sparkfun/SparkFun_gpio_Arduino_Library)

This package can be used in conjunction with the overall [SparkFun qwiic Python Package](https://github.com/sparkfun/Qwiic_Py)

class qwiic_gpio.QwiicGPIO(address=None, i2c_driver=None)

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:

The GPIO device object.

Return type:

Object

begin()

Initialize the operation of the Qwiic GPIO

Returns:Returns true of the initializtion was successful, otherwise False. Return type:bool

getGPIO()

Updates mode_X variables with values from Qwiic GPIO

Returns:The value of the mode register. Return type:8 bit unsigned integer

getInversion()

Updates inversion_X variables with values from Qwiic GPIO

Returns:The value of the inversion register. Return type:8 bit unsigned integer

getMode()

Updates mode_X variables with values from Qwiic GPIO

Returns:The value of the mode register. Return type:8 bit unsigned integer

isConnected()

Determine if a Qwiic GPIO device is connected to the system..

Returns:True if the device is connected, otherwise False. Return type:bool

setGPIO()

Send all current output settings to the GPIO. This should be called after calling myGPIO.out_status_0 = myGPIO.GPIO_HI to set the GPIO.

Returns:No return value

setInversion()

Send the inversion modes of all pins. This function must be called after editing modes using myGPIO.inversion_0 = myGPIO.INVERT

Returns:No return value

setMode()

Sends all 8 pin modes (input or output) to the GPIO to set all 8 pins. Setting the value to input or output is done using myGPIO.mode_0 = myGPIO.GPIO_OUT

Returns:No return value
