------------------------------------------
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 stm32f30x_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_cm0.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
