/**
|
||
|
|
* Marlin currently requires 3 SPI classes:
|
||
|
|
*
|
||
|
|
* SPIClass:
|
||
|
|
* This class is normally provided by frameworks and has a semi-default interface.
|
||
|
|
* This is needed because some libraries reference it globally.
|
||
|
|
*
|
||
|
|
* SPISettings:
|
||
|
|
* Container for SPI configs for SPIClass. As above, libraries may reference it globally.
|
||
|
|
*
|
||
|
|
* These two classes are often provided by frameworks so we cannot extend them to add
|
||
|
|
* useful methods for Marlin.
|
||
|
|
*
|
||
|
|
* MarlinSPI:
|
||
|
|
* Provides the default SPIClass interface plus some Marlin goodies such as a simplified
|
||
|
|
* interface for SPI DMA transfer.
