- ------------------------------------------
- 1. The SysTick_Config() function is a CMSIS function which configure:
- - The SysTick Reload register with value passed as function parameter.
- - Configure the SysTick IRQ priority to the lowest value (0x0F).
- - Reset the SysTick Counter register.
- - Configure the SysTick Counter clock source to be Core Clock Source (HCLK).
- - Enable the SysTick Interrupt.
- - Start the SysTick Counter.
-
- 2. You can change the SysTick Clock source to be HCLK_Div8 by calling the
- SysTick_CLKSourceConfig(SysTick_CLKSource_HCLK_Div8) just after the
- SysTick_Config() function call. The SysTick_CLKSourceConfig() is defined
- inside the misc.c file.
-
- 3. You can change the SysTick IRQ priority by calling the
- NVIC_SetPriority(SysTick_IRQn,...) just after the SysTick_Config() function
- call. The NVIC_SetPriority() is defined inside the core_cm3.h file.
-
- 4. To adjust the SysTick time base, use the following formula:
-
- Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
-
- - Reload Value is the parameter to be passed for SysTick_Config() function
- - Reload Value should not exceed 0xFFFFFF
