Function Documentation

◆ HAL_InitTick()

__weak HAL_StatusTypeDef HAL_InitTick ( uint32_t TickPriority )

This function configures the TIM6 as a time base source.

This function configures the source of the time base.

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

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 reconfigured by HAL_RCC_ClockConfig().; In the default implementation, SysTick timer is the source of time base. It is used to generate interrupts at regular time intervals. Care must be taken if HAL_Delay() is called from a peripheral ISR process, the SysTick interrupt must have higher priority (numerically lower) than the peripheral interrupt. Otherwise the caller ISR process will be blocked. The function is declared as __weak to be overwritten in case of other implementation in user file.

Parameters

TickPriority Tick interrupt priority.

Return values

HAL status
