PLATFORM_BUTTON_CONFIGURATION

typedef struct {
  unsigned char pin;
  unsigned char attributes;
  unsigned char mode;
  const char *name;
} PLATFORM_BUTTON_CONFIGURATION_t;

PLATFORM_BUTTON_CONFIGURATION_t describes the features of a button connected to a GPIO.

pin: The digital pin that senses the button. See PLATFORM_PIN_CONNECTION_t.
attributes: The attributes of the button. See PLATFORM_BUTTON_ATTRIBUTE_t.
mode: The mode to set the pin, should it be connected by a GPIO. See PLATFORM_PIN_MODE_t. Some boards rely on integrated pull-up or pull-down resistors for buttons rather than using an external resistor. You can specify the pull-ups or pull-downs by setting this member appropriately.
name: The name of the button. You can set this to the name of the button on the silkscreen or whatever is visible to the user for identification. If name is zero, the button's name is derived from the GPIO connection name for pin or the pad name for pin. See platform_button_name.
