Concept Board Arduino TFT Shield
How to use the Adafruit Arduino 1.8’’ TFT Shield with the Concept Board
The library and demo application were created by student workers at the Gemalto M2M Application Engineering department in Berlin - first of all Roman Wedemeier.
• Concept Board connected to a Windows 7 PC
• Adafruit 1.8’’ TFT shield with RST pin tied to the 5V pin
• Eclipse Juno with MTJ installed
• Gemalto EHSx Software Development Kit
• DisplayDriver and DisplayTest projects
Import Library and demo projects
Import DisplayDriver and DisplayTest into your workspace:
General->Existing Projects into Workspace
Select your project directory and the projects you want to import
Click Finish to import the selection into your workspace
Start demo application
Before starting the demo application, please check what kind of display you have. Depending on which display you are using you can to change the type of label to “BLACK_LABEL” or “RED_LABEL” in the DTest.java in line 45.
Create a new run configuration for DisplayTest:
Right-click the DisplayTest project. Choose Run As -> Run Configurations… .
Double-click Emulated JavaME MIDlet in the left menu of the new window. Set the executable to MIDlet and click “Search…”. In the new Window select DTest – (default package) and click OK. Adjust the Name of your new configuration, click Apply and Run afterwards.
You are now ready to launch the DTest MIDlet with your new Run Configuration.
Use demo application
On startup the demo displays text on the TFT.
When you press BTN-A the demo switches to graphical **** where you can move a little bird around with the joystick. Pressing the joystick changes the background image.
To end the application press BTN-B.
Use your own images
You can store new images in the project’s subfolder src/res or directly in the module using the Module Exchange Suite.
The images must be 16bit BMP (RGB565) encoded without "color space information". For further information please see the class adafruitST7735R.ImageBMP.
You’ll need to adjust the image paths in DTest.java to match your new image file names.
