Qwiic GPIO Example 3

Example 3 demonstrates how to invert an I/O pin configured as an input. We first set all eight pins as inputs and

then invert half of them using the

function. As we covered in the Arduino Examples section,

setInversion(self)

each I/O pin set as an input defaults to an active HIGH input so inverting it switches it to an active LOW input.

Again, note that you need to define the inversion status of each pin you wish to invert and then write that data

using the

function.
