Okay well talk is cheep. So I slapped together a real really quick video of my current project, you know the touch screen remote control system, just to show it works.. Well sort of.
Right now the features working are, a debug menu accessed via the USB port. You can communicate directly with the 4D Systems touch screen with this interface, as well as decode several different types of Remote Control IR signals.
The actual touch screen is running on its own cog in the propeller. It just continually runs scripts stored on an uSD card. There are three different types of files it uses. A script File, a button File, and an image file. Scripts run a very limited script language I have written for it. It just does things like load an image, pause, load a different script, pause some more, load a button file.... The button files contain coordinates for the touch screen and a script name to go along with that.
So at boot up it runs a boot script witch loads a button file. When the script finishes running it waits for you to press the touch screen. When you press the touch screen it looks to see if there is button defined in that spot and if so run the script. That script may or may not load a new button file so commands that don't require a new menu will not need to update what the buttons do.
What that all boils down to is the entire thing is fully configurable via simple test editor, and a tool 4D systems provides to convert images into a format it can play.
Okay not a lot of detail... But here is the first video of it in action...
