Part Number: TM4C129XNCZAD


Dear Sir,

I have drawn the rectangular button widget  on LCD and Pressing that button I perform the some measurement .

Using timer I am sending above  measurement data on Uart periodically.

The same screen replicate on Tablet LCD and pressing the start button over there take the event on Device LCD.(Bluetooth media used)

How we can send the press event for above button on UART?

My requirement is that Remotely press the above button on UART.

    Hello Rajesh,

    Sorry that I am not fully understanding your application. The remote / Bluetooth aspect is not very clear to me.

    Can you explain in more detail how the TM4C129 is connected to the system and how the LCD and UART are connected to different elements?

    Like for example it is not clear to me if you are controlling the Bluetooth module with TM4C UART?

    And it is also not clear what you mean by 'remotely press button on UART'?

    Best Regards,

    Dear Ralph

     

    My Device design have TM4c129XCNZAD with kentec LCD display 3.5 inch display.

    We have connected Bluetooth module  to One of the UART i.e UART3

     

    As already share the implemented widget video.

    In that video when I press start button then measurement start and simultaneously sending data to UART3 i.e Connected Bluetooth module.

     

    The Client side application have one tablet which having same GUI as displayed in video. The tablet is paired with our device through Bluetooth.

     

    My requirement is that  I don’t want to press button on device widget to start the measurement .Instead of that when I press the button on client side tablet GUI which is same as my device widget  then measurement start because it is connected through Bluetooth.

     

    Through Client side application I want to trigger the touch event on device widget.

     

     

    How can achieve this?

    Hello Rajest,

    I don't think you need a touch event here. I think you need the UART3 which is connected to your Bluetooth module to look for a specific message from the BT module and then when received, trigger the measurement.

    The touch event on device widget should only work for the LCD on that specific board. Touches on the 'tablet' side should just be communicated via Bluetooth and let the UART handle what should be done.
