Shown on this slide is a setup of the evaluation kit for the L6470. This kit includes the L6470 evaluation board, an interface board that connects to the USB port of the PC and translates the commands from the PC to the SPI interface for the L6470, and the software with a graphical user interface that runs on the PC. In the example that follows, the setup is driving a small stepper motor that is rotating a disk. There is also an oscilloscope running on the PC so that the current in one of the phases of the motor can be monitored.
