GTOP A support tool suite that provides an easy way to transfer images/files and perform visual GUI prototyping on our GT-CP (GU-TFT) displays. GTOP_icon

GTOP provides a quick and easy way to evaluate our GT-CP (GU-TFT) modules. This application allows you to display images on GT-CP (GU-TFT) modules, and create graphical user interface (GUI) prototypes. Choose from either USB or UART to communicate with any of our GT-CP (GU-TFT) displays.

This tool combines our GT-Packer and GTO TOOL into a single support tool suite.

Note: This tool is deprecated. The GTOP will merge into GTOMP, and the GTOP (and combined tools) will not receive any more updates after GTOMP is released. Please use the GTOMP.

Download Update: 12-27-2018

System Requirements:

  • Microsoft Windows 7/8.1/10 (32/64-bit) with .NET framework 4.0 or 4.5
  • Serial communication port (USB / UART)
  • 7MB of hard drive space

Application Setup:

  1. Unzip the downloaded file into a folder that you wish to keep GTOP. It is recommended to keep it in a new folder to avoid confusion with your existing files. You should now have the GTOP execution file, WinUSB installer for Windows 7 and GTOP user guide.
  2. The USB communication driver needs to be installed next. If you are using Windows 8.1/10, please skip forward to step 3. If you are using Window 7, please continue to the next step.
    1. Unzip
    2. Connect your GT-CP module to your PC via USB.
    3. If you have not installed WinUSB or a Noritake virtual COM port driver before, the driver installation will fail. When it does, go to your PC’s Device Manager.
    4. Right click on “GT800X480A-C903PA” or “GT480X272A-C903PA” and choose “Update Driver Software”.
    5. Click on “Browse my computer for driver software”.
    6. Click “Browse” and navigate to WinUSBdriverForWin7/winusbcompat.
    7. Click on “Next”.
    8. The driver should install and finish by saying that the “WinUSB Device” driver has been installed.

    * WinUSB is already packaged with Windows 8.1/10 so only install it on Windows 7.

    * If you don’t want to use WinUSB or if you encounter an error during installation, install our GU-TFT driver from this page.

  3. Connect your GT-CP module to your PC via USB.
  4. Launch the GTOPXXXX.exe file. The main GTOP window should appear.
  5. You can now use this tool to evaluate your Noritake GT-CP.

Display a bitmap image on your GT-CP module:

  1. With your GT-CP module connected to your PC and GTOP open, click the “Memory Tool” button.
  2. Once the “Memory Tool” window has opened, select the serial port that your module is connected to or select “Noritake Display” if you are using WinUSB.
  3. Once the connection is successful, navigate to the image that you would like to display in Windows Explorer.
  4. Drag and drop the image to the FROM2 node located on the left side of the Memory Tool window.
    • NOTE: The recommended image size is 800 x 480 pixels (or 480 x 272 pixels). Image processing time increases as image resolution increases.
  5. A new node will appear underneath the FROM2 node. Click this new node.
  6. The image will then load into the “Preview” section of the application.
  7. Once the image has appeared in the “Preview” section, check the “on GT” checkbox.
  8. The image will now be displayed on the module.
