* 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 .
