Use of different pins for SPI with GxEPD2

[ZinggJM]

@michaelschnyder

I wanted to know what the rationale is to default to the HSPI bus, when using the GxEPD2. I see I could easily adjust the Ctor and pass either the Bus-ID or Pins there, which could be passed to the SPI Init.

Yes, you can. Keep it simple was the design goal when I started GxEPD2.
But you can easily create your own GxEPD2_EPD class for your need.

GxEPD is easier to adapt. You could create your own GxIO_SPI class.

Welcome to the forum! I don't like to have to justify my design decisions.
