The Windows Application
The DRV8834EVM Windows application is the software counterpart for the DRV8834 EVM. It allows the
PC computer to connect to the MSP430F2617 microcontroller though an USB interface chip. Once
connection is established and commands are sent, microcontroller takes care of configuring control
signals and administering certain levels of automation, such as microstepping coordination, stepping rate
acceleration and deceleration, ITrip configuration and PWM generation.
The graphical user interface (GUI) has been designed to allow for all of the DRV8834 device’s
functionality to be tested without having to intervene with the hardware, except for the adjusting of the
reference voltage and decay selector switches.
