I am curious about this setup.
Is it possible to have the ESP wifi co-processor and an ILI9341 LCD connected to the Itsybitsy M4 at the same time using SPI?

I doubt it will work with a single SPI peripheral, the way it’s implemented right now. You might be able to use two different peripherals though.
Thanks @mmoskal. I don’t have enough pins left on the Itsybitsy M4 for another SPI. The @Adafruit Grand Central M4 can accomodate an additional SPI which I may try soon.
