TV Display - Great, but difficult to do much work in the space that's left
I am building a video controller for my (professional) Sony video cameras. ( Using a motorized Pan/Tilt head, with ELM Lanc chips to control the camera functions.) I have Javelin chips controlling the pan/tilt-camera LANC (which I will change to Propeller - should be able to put the LANC contoller in a COG), but for now, I really would like to use the Propeller as the user interface. ( I have LCD TV's coming out of my ears.........
)
Started building a simple UI, with buttons, with text on each, but quickly run out of space in memory. The double buffered bitmaps really eat it up.
Any suggestions, thoughts, etc on how to make the TV display more useful,
Thx,
Mike

Those efficient text displays will cut your video RAM needs by 90%! If text is okay, that's the way to go. Also, you can make your own character definitions for buttons and the like. The only caveat is that they must be placed at 64-byte boundaries so that the 10-bit field in the word which defines the character and color in screen memory can be shift left 6 bits to get the base of the cell definition.
