Block Diagram www.ti.com Jumpers The DRV8834EVM module contains three 2-pin jumpers which the user can remove in order modify certain aspects of configuration. • JP1: Place a shunt to enable the D1 LED signaling of any fault occurrence. • JP3: Place a shunt to allow 3.3-V supply to the microcontroller. Remove the shunt to disable MSP430 microcontroller and use external microcontroller of choice. - Page 5 3. In the newly open installation pop-up window, click Next.

Page 15: The Windows Application
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 Windows Application www.ti.com Figure 20. DRV8834EVM.exe Main Screen All the control signals needed to control motor enablement (nENABLE or ENABLEx), direction of rotation (PHASEx or DIR), current control (VREFx) and PWM control for both enablement and direction control signals are made available throughout one of the three control tabs. - Page 17 The algorithms offer accurate acceleration and deceleration profiles which help in the obtaining of better motion quality and performance.
