Multiple TFT displays

Jun. 29, 2023 Multiple TFT displays

Got the example code running on the TFT displays. I’m using the TFT_eSPI library and a Lolin S2 Mini (my new favorite board) to drive the displays. However, the problem is that the library only supports driving one display at a time. However, since they use SPI protocol to communicate, I guess I’ll have activate and deactivate the Chip Select pins of the displays real quick when I’m updating one of them.

The only problem is that the update/refresh speed will also get reduced from the perspective of the Serial Clock with this method. Let’s see.
