/**
|
|
* HARDWARE VS. SOFTWARE SPI COMPATIBILITY
|
|
*
|
|
* DUE selects hardware vs. software SPI depending on whether one of the hardware-controllable SDSS pins is in use.
|
|
*
|
|
* The hardware SPI controller doesn't allow software SPIs to control any shared pins.
|
|
*
|
|
* When DUE software SPI is used then Trinamic drivers must use the TMC softSPI.
|
|
*
|
|
* When DUE hardware SPI is used then a Trinamic driver can use either its hardware SPI or, if there are no shared
|
|
* pins, its software SPI.
|
|
*
|
|
* Usually the hardware SPI pins are only available to the LCD. This makes the DUE hard SPI used at the same time
|
|
* as the TMC2130 soft SPI the most common setup.
