Hello,

Could you be more precise ?

You want to be able to type on a qwerty keyboard and what you write is displayed on the screen right ?

But what board are you using ? You want to plug a qwerty keyboard to your board ?

You can look at this documentation page as a start : https://support.touchgfx.com/docs/development/board-bring-up/example-gpio

Please provide more information.

Yes I'm able to type on qwerty keyboard with touch and its displaying on the screen.

As a start I went through that document also and I also integrated the physical button, now I am not getting how to make qwerty keyboard to react to the hardware button as i want to operate the qwerty keyboard using joystick buttons not with touch.

STM32H743I-eval board we are using.

I'm not getting the logic to make qwerty keypad to react to those buttons.......

Using those buttons I wanted to type on the qwerty keyboard and need to display that.

Hello,

You will find examples available at this page. It will show you how to propagate the buttonController data to the GUI and use it.

[KM L.1]

I have written like this

[KM L.1]

uint8_t msg = 0;

if (xQueueReceive(gui_msg_q, &msg, 0) == pdTRUE)

 {

  // Queue is used as a flag, so don't check msg.

  // Full = PRESSED, Empty = Do nothing.

   btnPressed();

 }

#endif

}

[KM L.1]

void MainView::getBuffer() // add

{

}

how to use the custom keyboard function over here to operate using button
