  • Page 16: Software Description

    Software Description Software Setup The KIT912F634EVME is designed to communicate with the PC or notebook (as the master) via the USB interface. The communication is bidirectional. The orders are sent from master, and the status information is sent from the slave (kit) to the master. The communication methods are described in Figure 6.
