Running the Application

The Vendor device can be exercised by using the WinUSB PnP Demonstration application, which is provided in your installation of MPLAB Harmony.

The LEDs on the demonstration board will indicate the USB state of the device. This application allows the state of the LEDs on the board to be toggled and indicates the state of a switch (pressed/released) on the board. Refer to the Configuring the Hardware section for the selected target hardware.

To launch the application, open the executable WinUSB_PnP_Demo.exe from the folder path usb_apps_device/apps/vendor/bin/WinUSB_PnP_Demo.exe. A dialog box similar to the following should appear:

The appropriate device family that is under testing should be selected in the utility. Pressing the Toggle LED button will cause the LED on the board to toggle. The Pushbutton State field in the application indicates the state of a button on connected USB Device. Pressing the switch on the development board will update the Pressed/Not Pressed status of the Pushbutton State field. Note: The device family under test should be selected appropriately. An incorrect selection will result in an invalid push button status. Windows Operating system may select a wrong driver by default. If the application does not run as expected it is suggested to look into the Windows Device Manager and see if the Microchip WinUSB Device is not shown with a Yellow mark. If so, the drivers should be selected manually from the application path.

Manual selection of Drivers

To specifically select the driver, open the device manager and look for device named as WinUSB Device with a Yellow mark. Right click and select Update Driver Software. Select Browse my computer for drivers. Select the drivers in application path ..\usb_apps_device\apps\vendor\driver.
