Use MISO pin for display D/C?

Other Hardware Displays

for displays that don't a slave-out pin, can the MISO pin of the master be used for the display's Data/Command, specifically when there are more slaves on the bus. would this cause any issues?

If you are using the hardware SPI (SPI.h) then this is always reserved for MISO even if you don't use it for that function.

I think you can use it on most platforms, if you call pinMode(MISO, ..) after SPI.begin() has been called.
