DRV8803/04/05/06 Evaluation Module
4 The Windows Application
The DRV8803-04-05-06 EVM Windows application is the software counterpart for the DRV8803/04/05/06.
It allows the PC to connect to the MSP430F2617 microcontroller through 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.
Figure 24 shows the DRV8803-04-05-06 EVM High-Level Page.
The GUI has four High-Level Pages:
• DRV8803
• DRV8804
• DRV8805
• DRV8806
It contains frames with GPIO control for the DRV8803-04-05-06 control signals, stepper motor control
for start/stop and speed, and Acceleration control.
