2.2Installing the DRV8811 Evaluation Board Windows Application Software
The included CD contains a folder titled “Windows Application”. It is recommended for the contents of this folder to be copied to any desired folder on the computer. The reason for this is the Settings.ini file will be written upon software exit. This action can not take place if the application is run within the CD environment.
2.3Running the Windows Application Software
To run the application, double click the DRV8811_RD_EVM_R1p0.exe application icon found in the same folder the application was extracted into.
3Windows Application
The DRV8811 Windows Application is the software counterpart for the DRV8811 EVM. It is in charge of connecting to the MSP430 microcontroller via a USB connection which in turn selects the proper logic state for the DRV8811 control signals.
The graphical user interface (GUI) has been designed to allow for all of the DRV8811 device’s functionality to be tested without having to intervene with the hardware, except for the proper configuration of jumpers when needed.
Figure 3 shows the DRV8811_RD_EVM_R1p0.exe main screen. It contains menu items to configure and enable/disable the serial port, frames with GPIO control for the DRV8811 control signals, stepper motor control for start/stop and speed, and current/decay control through the MSP430 DACs.
