Setup the Display

The widgets on the gen4 Display were created using the ViSi-Genie environment in Workshop4. ViSi-Genie is an environment that allows users to create GUIs (Graphical User Interface) by drag-and-drop method. The ViSi-Genie project file for this demo can be found inside the attached zip file

Download and Install Workshop4
- To get started, download and install the Worskhop4 IDE from the 4D Systems website, then open the attached project.
- Extract the attached zip file to a folder then open the ViSi-Genie project “demo1”, as shown below.
- Download the project here.
- You can edit the widgets in each form by using the Object Inspector.

Check the Project Settings
- After opening the project file, go to the Project menu and make sure that the Comms Speed and Display parameters are correct as shown below.
Connect gen4-uLCD-35DT to the PC
- Use gen4-interface board and uUSB PA-5 to connect the display to the PC as shown in the image below.
- Or if you have gen4-PA board, connect the display to the PC as shown in the image below. You can also use the gen4-PA board if you want to use its GPIO pins.
- Now go to the Comms Menu and select the correct COM port for the uUSB-PA5, then click on the red button, as shown below.
- If the gen4 Display is properly connected to the PC, the red button should now turn blue and the name of the display module should be displayed, as shown below.
