Description
For reported bug #21112 ([BUG] LCD AZSMZ 12864 display freezes when SD card is present #21112) the following fixes a display problem that was specific to a SMART RAMPS board with an Arduino MEGA 2650 -- something that was only recently enabled.
Requirements
It is specific to users of SMART RAMPS board with a MEGA 2560.
Benefits
In the case of a SMART RAMPS board, pre-compiler directives were such that SPI was forced to be software emulated -- this was intended for the DUE. However, for the MAGA 2560, there is hardware SPI support on the same pins configured. Hence, adjust switches to allow use of hardware SPI for this case.
With that, the display works nicely with the SD Card in use now.
