On the PJRC page for the 2.8" TFT display (here), Paul gives the T3.x SPI connections for the display, with and without the Audio Board. This page has not been updated for use with the T4.
I'm just getting around to wiring up a T4 with both a display and an Audio Board, and I'm confused how to handle the situation. It seems the T3.6 had just one SPI port and a set of alternate pins, but the T4 has multiple ports and no alternate pins. So how do we handle it?
The Audio Board is working well on SPI0 on its own, but how do I handle the display as well? I've searched the forum and looked at the libraries...
