TM4C129XNCZAD: How to get started on touch screen design, any user groups?

Mark Sheats

Part Number: TM4C129XNCZAD

I'm taking over a project that uses this microcontroller and the instrument has a touch screen, the same one on the development kit board.  I have never done touch screen programming before, and the code has lots of functions, like tPushButtonWidget, tCanvasWidget, CircularButtonStruct, RectangularButtonStruct, and so on.

When I search the project I don't come up with any more information on these things.

How do I start learning about all these?

In the old days I attended a local user group for National Instruments LabVIEW.  Is there any such thing for embedded developers?  Any way to meet and talk with other programmers?

Thanks,

Mark

    Hi Mark,

      In TivaWare SDK you can find many of the examples in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\dk-tm4c129x that will display the outputs on the LCD screen. In interact with the LCD using buttons you can run the grlib_demo project. This demo contains a series of panels show different features of the graphic library. For each panel, the bottom provides a forward and back button, along with a brief description of the contents of the panel.

      Please also refer to graphic library user's guide https://www.ti.com/lit/pdf/spmu300

      This app note https://www.ti.com/lit/pdf/spma082 will be also useful for instroduction to TivaWare graphic library.
