SPI Master with Multiple MDriveAC Plus Microstepping
It is possible to link multiple MDriveAC Plus 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 MDriveAC Plus on the bus will have a dedicated chip select. Only one system MDriveAC Plus can be communicated with/
Parameters changed at a time.
