  • Touch screens supported

    Does the Picaso GFX or 4DGL support touch screen monitors? I see support for all the tiny 4D touch screens but I would like to connect a full size touch monitor. When I say full size, I mean 15", 19", 20", etc. with VGA connector.

    You should be able to get VGA monitors (various sizes) with integrated touch panels (try ebay). The touch control is either USB or Serial RS232. Use the uVGA-II(GFX) and interface the Serial Touch to the 2nd serial port (COM1) of the uVGA-II.
    Soon we'll be offering integrated touch panel VGA monitors with the uVGA-II to do exactly what you require.
    Edit: The serial port on the touch panels are true RS232 levels and COM1 (TX1/RX1) on the uVGA-II(GFX) are TTL levels. Make sure you convert the RS232 levels down to TTL levels.

      There is no direct touch capability on uVGAII, external pointing devices can be connected via COM0, COM1 or I2C ports:

      Some examples can be found here:-
