- Display true-color images
- Create a dynamic user interface
- Show data with gauges and dials
- Use touchscreen input in your project
Step 1: Example: Webcam Viewer
The Propeller connects to the Internet, grabs the webcam image and caches it on an SD card. Then, it updates the touchscreen every minute or so with the most current webcam image. Here's the sourcecode with usage notes.
Step 2: Example: Program Chooser
The chooser is stored on EEPROM and other programs are stored on the SD card. When you make a selection the chooser loads up whatever program was selected. The loaded program can be anything, whether it uses a screen or not. Here's the code for this project.
