Figure 10. Menu
The menu at the top of the application offers a series of quick options for how the COM port is to behave,
and an option to view functional block diagrams of the respective chip. Please refer to the datasheet for
the most updated functional block diagrams.
File:
Exit - Terminates the application.
Com Port Selection Box:
Port - Selects port from drop down combo box. Default is COM4.
The Serial Port actual port number defaults to what we have specified on the
“USB_Drivers_Install_Readme.pdf”. However, any port between COM 1 and COM 4 are equally usable.
Connect: Opens the Serial Port. When this menu item is pressed, its caption changes to “Disconnect”.
Disconnect: Closes the Serial Port. When this menu item is pressed, its caption changes to “Connect”.
Configure Device: This button will clear all parameters back to original settings, and also identify for the
MCU which device is being implemented on the EVM (DRV8803/04/05).
After opening the application, the order of events should be:
Go to Com Port Selection Box and choose the COM Port where the FTDI device has been configured
to work. If the COM port is 4, then this step can be skipped, as application defaults to COM4.
Press Connect. If the port is available, the menu changes the “Connect“ caption to “Disconnect“. Press
Disconnect if wanting to disable the serial communications.
After toggling the enable pin command button, 1-0-0 should return on the status strip at the bottom of
the application as an acknowledgement of communication between the com port and the device.

View: Under view there is an option “Schematic” which takes the user to a menu of different device
schematics that are available for viewing.
