SPI Master with Multiple MDrivePlus Microstepping
It is possible to link multiple MDrivePlus Microstepping units in an array from a single SPI Master by wiring the system and
programming the user interface to write to multiple chip selects.
Each MDrivePlus on the bus will have a dedicated chip select. Only one system MDrivePlus can be communicated with/Pa-
rameters changed at a time.
