Are there any example for interfacing external buttons ?

I'm not able to implement in the right way following this guide.

Thank you

Hi,

In the backend communication article in the documentation you can download projects on different boards using external buttons.

Add next key ...

if (HAL_GPIO_ReadPin(GPIOC, GPIO_PIN_13) != GPIO_PIN_RESET)

{

key = 1;

return true;

}

if (HAL_GPIO_ReadPin(GPIOXX, GPIO_PIN_XX) != GPIO_PIN_RESET)

{

key = 2;

return true;

}

and to project

"PhysicalButtons": [

{

"Key": 1,

"Name": "BTN_USER"

},

{

"Key": 2,

"Name": "BTN_USERXX"

}

],

...

Too you can aliasing gpio to keyboard keys ... and simply in model tick use

if (HAL_GPIO_ReadPin(SW_PWR_GPIO_Port, SW_PWR_Pin) == GPIO_PIN_RESET && filter == false )

 {

  filter = true;

  static_cast<FrontendApplication*>(Application::getInstance())->handleKeyEvent(85);

 }

85 is defined as key "U" in trigger designer...
