HAL CORTEX SYSTICK functions migration ¶

Note

The SYSTICK migration is applicable with all STM32 series.

HAL_SYSTICK_Config ¶

HAL1	HAL2
The function `HAL_SYSTICK_Config` is responsible for configuring the SysTick timer to generate an interrupt at a specified number of ticks using TicksNumb:	This function has been updated and renamed to `HAL_CORTEX_SYSTICK_SetFreq`: Functionality Update: Replace Ticks_num (expressed in time) by ticks_freq (expressed in frequency).
uint32_t HAL_SYSTICK_Config(uint32_t TicksNumb)	hal_status_t HAL_CORTEX_SYSTICK_SetFreq(uint32_t ticks_freq);

HAL1

HAL2

The function HAL_SYSTICK_Config is responsible for configuring the SysTick timer to generate an interrupt at a specified number of ticks using TicksNumb:

This function has been updated and renamed to HAL_CORTEX_SYSTICK_SetFreq:

Functionality Update:

Replace Ticks_num (expressed in time) by ticks_freq (expressed in frequency).

                uint32_t HAL_SYSTICK_Config(uint32_t TicksNumb)

               

                hal_status_t HAL_CORTEX_SYSTICK_SetFreq(uint32_t ticks_freq);

HAL_SYSTICK_CLKSourceConfig ¶

HAL1	HAL2
The function `HAL_SYSTICK_CLKSourceConfig` was responsible for configuring the clock source for the SysTick timer:	This function has been updated and renamed to `HAL_CORTEX_SYSTICK_SetClockSource`: Functionality Update: Use specific enumeration hal_cortex_systick_clk_src_t for the clock source parameter, enhancing type safety and clarity.
void HAL_SYSTICK_CLKSourceConfig(uint32_t CLKSource)	void HAL_CORTEX_SYSTICK_SetClkSource(hal_cortex_systick_clk_src_t clk_src)

HAL1

HAL2

The function HAL_SYSTICK_CLKSourceConfig was responsible for configuring the clock source for the SysTick timer:

This function has been updated and renamed to HAL_CORTEX_SYSTICK_SetClockSource:

Functionality Update:

Use specific enumeration hal_cortex_systick_clk_src_t for the clock source parameter, enhancing type safety and clarity.

                void HAL_SYSTICK_CLKSourceConfig(uint32_t CLKSource)

               

                void HAL_CORTEX_SYSTICK_SetClkSource(hal_cortex_systick_clk_src_t clk_src)

               

HAL_SYSTICK_GetCLKSourceConfig ¶

HAL1	HAL2
The function `HAL_SYSTICK_GetCLKSourceConfig` was responsible for returning the current SysTick clock source.	This function has been removed, the current SysTick clock source is read directly from CMSIS.

HAL_SYSTICK_IRQHandler ¶

HAL1	HAL2
the function `HAL_SYSTICK_IRQHandler` is responsible for handling SysTick timer interrupt requests:	This function has been renamed to `HAL_CORTEX_SYSTICK_IRQHandler`:
void HAL_SYSTICK_IRQHandler(void)	void HAL_CORTEX_SYSTICK_IRQHandler(void)

HAL_SYSTICK_Callback ¶

HAL1	HAL2
The function `HAL_SYSTICK_Callback` was responsible for providing a user-defined callback function for SysTick timer interrupts:	This function has been renamed to `HAL_CORTEX_SYSTICK_Callback`:
void HAL_SYSTICK_Callback(void)	void HAL_CORTEX_SYSTICK_Callback(void)
