The DRV8818EVM is a complete solution for evaluating the DRV8818 micro stepping, bipolar stepper driver. It includes a USB link to provide easy control from a personal computer (PC), a MSP430 microcontroller that interprets serial commands from the PC and generates control signals to the driver device, and the DRV8818 device with access to all signals for a complete evaluation. The evaluation module uses a combination of terminal blocks and test clips for the application and monitoring of power. The only power rail that the user must supply is VM for the device's power stage. VDD for logic levels is internally generated from the USB connection. The DRV8818 Windows application is the software counterpart for the evaluation module. This application is in charge of connecting to the MSP430 microcontroller by an USB connection, which in turn selects the proper logic state for the DRV8818 control signals.
