I'm using nrf51822. I have a program which shut down the system when the button is clicked. however, not every time I click the button, the system respond. my system is full of other events (interrupts).
the BUTTON_DETECTION_DELAY
is set to 1 second. I want a long press before going down.
void buttons_init(void)
{
static app_button_cfg_t buttons[] = {
{ON_OFF_BUTTON_PIN_NO, false, NRF_GPIO_PIN_PULLUP, button_event_handler},
};
uint32_t err_code = app_button_init(buttons, sizeof(buttons) / sizeof(buttons[0]), BUTTON_DETECTION_DELAY);
APP_ERROR_CHECK(err_code);
err_code = app_button_enable();
APP_ERROR_CHECK(err_code);
}
void button_event_handler(uint8_t pin_no, uint8_t button_action)
{
// set turn off flag, and turn off from main loop
}
how can I set the button handler the rightest priority
