How to install driver for PCF8575?

I am a beginner working on a project which requires the use of PCF8575 16-Bit I2C I/O Expander with Interrupt. So, how to install the library and use it in the project. I have looked up the docs of OpenMV. But still, I can’t get around the problem, if anyone could help me out, it would be a great help.

You have to either find a microcpython driver for that or write your own.

Someone made one: GitHub - mcauser/micropython-pcf8575: MicroPython driver for PCF8575 16-Bit I2C I/O Expander with Interrupt
