It appears to me that pin 4 is the Wake button on the wiced sense. P0 is the pin which you should register the interrupt for.
To utilize the buzzer functions, you must register the buzzer pin in the GPIO configure table. The buzzer is on pin 13 on wiced sense.
Additionally, the easiest way to register an interrupt of a push button is by using the same GPIO configuration table as the buzzer. Your table should look like this:
const BLE_PROFILE_GPIO_CFG wiced_sense_gpio_cfg =
{
/*.gpio_pin =*/
{
GPIO_PIN_WP, // This need to be used to enable/disable NVRAM write protect
GPIO_PIN_BUTTON,
13, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1 // other GPIOs are not used
},
/*.gpio_flag =*/
{
GPIO_SETTINGS_WP,
GPIO_SETTINGS_BUTTON,
GPIO_SETTINGS_BUZZER, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
}
};
In addition to registering the button as your interrupt, you also need to define the callback that will fire when the button is pressed.
Put this into your create function:
// register interrupt handler for button inputs.
bleprofile_regIntCb((BLEPROFILE_SINGLE_PARAM_CB) button_interrupt_handler);
And define and declare your function:
static void button_interrupt_handler(UINT8 value);
void button_interrupt_handler(UINT8 value)
{
// On press.
if (value & 1)
{
//call buzzer functionality here
}
}
