Hi all,
i'm using an app_timer. I need to use three timer for debounce of three button. In my case i have to discriminate the push of three button at same time. When all three buttons has release, my FSM sends an event (ALL_THREE_BUTTON_IS RELEASE).
This is my ButtonHandel:
static void BUTTON_EventHandler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
uint32_t err_code;
BTN_Id_t lIdButton;
switch (pin)
{
case BTN_CENTRAL_PIN:
lIdButton = BTN_CENTRAL;
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_3);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_2);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_1);
APP_ERROR_CHECK(err_code);
err_code = TIMER_Start(TIMER_BTN_DEBOUNCE_BUTTON_1,TIMER_DEBOUNCE_DELAY,(void*)lIdButton);
APP_ERROR_CHECK(err_code);
break;
case BTN_SIDE_1_PIN:
lIdButton = BTN_SIDE_1;
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_3);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_2);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_1);
APP_ERROR_CHECK(err_code);
err_code = TIMER_Start(TIMER_BTN_DEBOUNCE_BUTTON_2,TIMER_DEBOUNCE_DELAY,(void*)lIdButton);
APP_ERROR_CHECK(err_code);
break;
case BTN_SIDE_2_PIN:
countrelese++;
lIdButton = BTN_SIDE_2;
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_3);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_2);
err_code = TIMER_Stop(TIMER_BTN_DEBOUNCE_BUTTON_1);
APP_ERROR_CHECK(err_code);
nrf_delay_ms(10);
err_code = TIMER_Start(TIMER_BTN_DEBOUNCE_BUTTON_3,TIMER_DEBOUNCE_DELAY,(void*)lIdButton);
APP_ERROR_CHECK(err_code);
break;
default:
break;
}
}
So when a last button was release, a timer debounce starts and check if all three buttons was release. But sometimes, the callback of this timer debounce not expire. But the err_code = TIMER_Start(TIMER_BTN_DEBOUNCE_BUTTON_3,TIMER_DEBOUNCE_DELAY,(void*)lIdButton); is called, but don't wxpire.
It's possible that app_timer.h library have a bug releated to STOP and START the same Timer?
Thanks, Anna
