mbed_official 573:ad23fe03a082 22 This section provides functions allowing to configure the NVIC interrupts (IRQ).

mbed_official 573:ad23fe03a082 30
mbed_official 573:ad23fe03a082 31 -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
mbed_official 573:ad23fe03a082 32 The pending IRQ priority will be managed only by the sub priority.
mbed_official 573:ad23fe03a082 33
mbed_official 573:ad23fe03a082 34 -@- IRQ priority order (sorted by highest to lowest priority):
mbed_official 573:ad23fe03a082 35 (+@) Lowest preemption priority
mbed_official 573:ad23fe03a082 36 (+@) Lowest sub priority

mbed_official 573:ad23fe03a082 40 *** How to configure Systick using CORTEX HAL driver ***
mbed_official 573:ad23fe03a082 41 ========================================================
mbed_official 573:ad23fe03a082 42 [..]
mbed_official 573:ad23fe03a082 43 Setup SysTick Timer for time base.
mbed_official 573:ad23fe03a082 44
mbed_official 573:ad23fe03a082 45 (+) The HAL_SYSTICK_Config() function calls the SysTick_Config() function which
mbed_official 573:ad23fe03a082 46 is a CMSIS function that:
mbed_official 573:ad23fe03a082 47 (++) Configures the SysTick Reload register with value passed as function parameter.
mbed_official 573:ad23fe03a082 48 (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
mbed_official 573:ad23fe03a082 49 (++) Resets the SysTick Counter register.
mbed_official 573:ad23fe03a082 50 (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
mbed_official 573:ad23fe03a082 51 (++) Enables the SysTick Interrupt.
mbed_official 573:ad23fe03a082 52 (++) Starts the SysTick Counter.
mbed_official 573:ad23fe03a082 53
mbed_official 573:ad23fe03a082 54 (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
mbed_official 573:ad23fe03a082 55 __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
mbed_official 573:ad23fe03a082 56 HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
mbed_official 573:ad23fe03a082 57 inside the stm32f7xx_hal_cortex.h file.
mbed_official 573:ad23fe03a082 58
mbed_official 573:ad23fe03a082 59 (+) You can change the SysTick IRQ priority by calling the
mbed_official 573:ad23fe03a082 60 HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
mbed_official 573:ad23fe03a082 61 call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
mbed_official 573:ad23fe03a082 62
mbed_official 573:ad23fe03a082 63 (+) To adjust the SysTick time base, use the following formula:
mbed_official 573:ad23fe03a082 64
mbed_official 573:ad23fe03a082 65 Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
mbed_official 573:ad23fe03a082 66 (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
mbed_official 573:ad23fe03a082 67 (++) Reload Value should not exceed 0xFFFFFF
