Other Parts Discussed in Thread: OMAPL138

Hi TI Experts:

When I connected J3 and J4 of Beagleboard xM LCD7 (ULCD7 from CircuitCo) to P1 and P2 of LCDK C6748, and run demoMain from StartWare_1_20_04_01 (project demo_c674x_c6748_lcdkC6748), the menu is displayed well. Touch function does not work. When I look at project files, demoTouch.c is there. I do not know how to make touch screen function work in demMain. could you please give a guideline how to make touch screen function work in demoMain project, or offer a project file to demo touch screen??

Thanks a lot!

Hi Mike,
I think, the demo has been initialized with mouse HID interface for navigation.
So, you have put the "TouchInit()" and with touch APIs to make it work.

You can connect USB HID mouse and able to access but not touch.
Just touch low level support had been enabled and you need to change the "demMain" code for touch support like "ReadAxis" , TouchCoOrdGet etc.,

Hi Titus:
would you please let your starterware team supplies an example for integrating LCD display and touch screen with LCDK C6748 and ULCD7 Lite?
Thanks!

Hi Mike,
We have already touch screen and LCD display APIs and you may need to develop application with that APIs.

We don't have any further development in starterware.
Sorry for the inconvenience.
