mbed_official 226:b062af740e40 22 This section provides functions allowing to configure the NVIC interrupts (IRQ).

mbed_official 87:085cde657901 30
mbed_official 87:085cde657901 31 -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ pre-emption is no more possible.
mbed_official 87:085cde657901 32 The pending IRQ priority will be managed only by the sub priority.

mbed_official 87:085cde657901 34 -@- IRQ priority order (sorted by highest to lowest priority):

mbed_official 226:b062af740e40 40 *** How to configure Systick using CORTEX HAL driver ***
mbed_official 87:085cde657901 41 ========================================================
mbed_official 87:085cde657901 42 [..]
mbed_official 226:b062af740e40 43 Setup SysTick Timer for time base.
mbed_official 87:085cde657901 44
mbed_official 226:b062af740e40 45 (+) The HAL_SYSTICK_Config() function calls the SysTick_Config() function which
mbed_official 87:085cde657901 46 is a CMSIS function that:
mbed_official 87:085cde657901 47 (++) Configures the SysTick Reload register with value passed as function parameter.
mbed_official 87:085cde657901 48 (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
mbed_official 87:085cde657901 49 (++) Resets the SysTick Counter register.
mbed_official 87:085cde657901 50 (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
mbed_official 87:085cde657901 51 (++) Enables the SysTick Interrupt.
mbed_official 87:085cde657901 52 (++) Starts the SysTick Counter.
mbed_official 87:085cde657901 53
mbed_official 87:085cde657901 54 (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
mbed_official 87:085cde657901 55 __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
mbed_official 87:085cde657901 56 HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
mbed_official 87:085cde657901 57 inside the stm32f4xx_hal_cortex.h file.
mbed_official 87:085cde657901 58
mbed_official 87:085cde657901 59 (+) You can change the SysTick IRQ priority by calling the
mbed_official 87:085cde657901 60 HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
mbed_official 87:085cde657901 61 call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
mbed_official 87:085cde657901 62
mbed_official 87:085cde657901 63 (+) To adjust the SysTick time base, use the following formula:
mbed_official 87:085cde657901 64
mbed_official 87:085cde657901 65 Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
mbed_official 87:085cde657901 66 (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
mbed_official 87:085cde657901 67 (++) Reload Value should not exceed 0xFFFFFF
