BeagleBone Black (BBB) & LCD7 Cape interfaced to Arduino

Here is a quick demonstration video of my BeagleBone Black (BBB) and the LCD7 cape interfaced to an Arduino controlling an LED. The LCD7 cape is a 7 inch 800×480 LCD with a resistive touchscreen.

    Thanks Javier!

    The easiest way to install Qt Embedded in Angstrom is to run ‘opkg update’ followed by ‘opkg install qt4-embedded –force-depends’.

      You´re welcome.

      I have done a lot of times as you say, but it does not work. Did you do another thing extra?

    Hello, thanks it works, but I have some problems the touch screen does work and I have events with the keyboard and it does not work too.
    Do you install some libs extra?

      You might need to calibrate your touch screen by running ‘ts_calibrate’. Also check the environment variables QWS_MOUSE_PROTO and QWS_KEYBOARD.
