@Frenzyritz13 I just modified my post (found/fixed an error in the logic). Please be sure to use the updated snippet about _ini_pins()

This looks good Brendan! Will test it and get back to you. Also, I am going to be using 2 I2Cs and an Expander based interrupt, I am expecting some issues there as well, will keep this thread updated.

This deserves a separate thread/issue because we are no longer discussing just the ESP32's SPI bus.
