SPI Master with Multiple Microstepping MForce PowerDrive

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