This demonstration is for checking the display of a JPEG image generated by Qt Design Studio via TRAVEO™ T2G Virtual Display Tool .
Note: This software modifications may not work correctly. Also, copy and republishing of this software assets is inhibited.
The device used in this demonstration is:
The board used for testing is:
- TRAVEO™ T2G Cluster 6M Lite Kit (KIT_T2G_C-2D-6M_LITE)
Through the integration of TRAVEO™ T2G MCU and Qt Design Studio design objects, it is possible to use the Qt Design Studio tool to create UI designs for TRAVEO™ microcontrollers and build and deploy them as part of the application. In this demonstration, you can display and check the JPEG images designed with Qt Design Studio using TRAVEO™ T2G Virtual Display Tool.
Graphic Subsystems
- Supports 2D and 2.5D (perspective warping, 3D effects) graphics rendering
- 40-bit for internal processing (RGBA 10-bit per color channel)
- 24-bit for interfaces (RGB 8-bit per color channel)
- 4096 KB of embedded video RAM memory (VRAM)
- Up to two video output interfaces supporting two displays from
- Parallel RGB (max display size: 1600 × 600 at 80 MHz)
- FPD-link single (max display size: 1920 × 720 at 110 MHz)
- FPD-link dual (max display size: 2880 × 1080 at 220 MHz)
- One Capture engine for video input processing for ITU 656 or parallel RGB/YUV or MIPI CSI-2 input
- ITU656 (standard camera capture: up to 800 × 480)

- Command sequencer for setup and control of the rendering process
- Supports graphics rendering without frame buffers (on-the-fly to both displays)
- Dual-channel FPD-Link interface for up to Wide-HD resolution video output
- JPEG Decoder
- Decodes JPEG images of various formats into pixel data with conformance to a subset of standard ISO/IEC10918-1
- Color spaces supporting RGB/YUV/Grayscale
- Supports YUV sub-sampling 4:4:4/4:2:2/4:1:1/4:2:0
- Image size between 1×1 to 16384×16384 pixels

This demonstration has been developed for:
- TRAVEO™ T2G Cluster 6M Lite Kit (KIT_T2G_C-2D-6M_LITE)
Figure 1. KIT_T2G_C-2D-6M_LITE (Top View)
No changes are required from the board's default settings.
Note: You need to download TRAVEO™ T2G Virtual Display Tool in advance. Because this demonstration uses the FX3 controller to display. Please make sure you have installed Qt Design Studio and have a valid license.
After code compilation, perform the following steps to flashing the device:
-
Connect the board to your PC using the provided USB cable through the KitProg3 USB connector.
-
Program the board using one of the following:
- Select the demonstration project in the Project Explorer.
- In the Quick Panel, scroll down, and click [Project Name] Program (KitProg3_MiniProg4).
-
After programming, the demonstration starts automatically.
-
Connect the board to your PC using the provided USB cable through the FX3 USB for outputting the JPEG.
- Note: It is not necessary to connect the Kitprog3 USB and the FX3 USB at the same time.
-
launch the TRAVEO™ T2G Virtual Display Tool.
-
Set the parameters on the Virtual Display Tool to run this demonstration and push the Start stream button.
-
It will be displayed the JPEG image from TRAVEO™ T2G Virtual Display Tool
