mbed_official 330:c80ac197fa6a 65 ========================================================
mbed_official 330:c80ac197fa6a 66 [..]
mbed_official 330:c80ac197fa6a 67 Setup SysTick Timer for time base.
mbed_official 330:c80ac197fa6a 68
mbed_official 330:c80ac197fa6a 69 (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
mbed_official 330:c80ac197fa6a 70 is a CMSIS function that:
mbed_official 330:c80ac197fa6a 71 (++) Configures the SysTick Reload register with value passed as function parameter.
mbed_official 330:c80ac197fa6a 72 (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
mbed_official 330:c80ac197fa6a 73 (++) Resets the SysTick Counter register.
mbed_official 330:c80ac197fa6a 74 (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
mbed_official 330:c80ac197fa6a 75 (++) Enables the SysTick Interrupt.
mbed_official 330:c80ac197fa6a 76 (++) Starts the SysTick Counter.
mbed_official 330:c80ac197fa6a 77
mbed_official 330:c80ac197fa6a 78 (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
mbed_official 330:c80ac197fa6a 79 __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
mbed_official 330:c80ac197fa6a 80 HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
mbed_official 330:c80ac197fa6a 81 inside the stm32f3xx_hal_cortex.h file.
mbed_official 330:c80ac197fa6a 82
mbed_official 330:c80ac197fa6a 83 (+) You can change the SysTick IRQ priority by calling the
mbed_official 330:c80ac197fa6a 84 HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
mbed_official 330:c80ac197fa6a 85 call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
mbed_official 330:c80ac197fa6a 86
mbed_official 330:c80ac197fa6a 87 (+) To adjust the SysTick time base, use the following formula:
mbed_official 330:c80ac197fa6a 88
mbed_official 330:c80ac197fa6a 89 Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
mbed_official 330:c80ac197fa6a 90 (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
mbed_official 330:c80ac197fa6a 91 (++) Reload Value should not exceed 0xFFFFFF
