Function Documentation

HAL_StatusTypeDef HAL_InitTick ( uint32_t TickPriority )

This function configures the RTC_ALARMA as a time base source. The time source is configured to have 1ms time base with a dedicated Tick interrupt priority.

Note: This function is called automatically at the beginning of program after reset by HAL_Init() or at any time when clock is configured, by HAL_RCC_ClockConfig().

Parameters

TickPriority Tick interrupt priority.

Return values

HAL status

Definition at line 113 of file stm32f7xx_hal_timebase_rtc_alarm_template.c.

void HAL_ResumeTick ( void )

Resume Tick increment.

Note: Enable the tick increment by Enabling RTC ALARM interrupt.

Parameters

None

Return values

None

Definition at line 253 of file stm32f7xx_hal_timebase_rtc_alarm_template.c.

void HAL_RTC_AlarmAEventCallback ( RTC_HandleTypeDef * hrtc )

ALARM A Event Callback in non blocking mode.

Note: This function is called when RTC_ALARM interrupt took place, inside RTC_ALARM_IRQHandler(). It makes a direct call to HAL_IncTick() to increment a global variable "uwTick" used as application time base.

Parameters
