3 The Windows Application
The DRV8803-04-05 EVM Windows application is the software counterpart for the DRV8803/04/05. It
allows the PC to connect to the MSP430F2617 microcontroller though an USB interface chip.
The Graphical User Interface (GUI) has been designed to allow for all of the DRV88xx device’s
functionality to be tested without having to intervene with the hardware, except for the proper configuration
of jumpers, when needed.
