mbed_official | 87:085cde657901 | 63 | ======================================================== |
mbed_official | 87:085cde657901 | 64 | [..] |
mbed_official | 87:085cde657901 | 65 | Setup SysTick Timer for 1 msec interrupts. |
mbed_official | 87:085cde657901 | 66 | |
mbed_official | 87:085cde657901 | 67 | (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which |
mbed_official | 87:085cde657901 | 68 | is a CMSIS function that: |
mbed_official | 87:085cde657901 | 69 | (++) Configures the SysTick Reload register with value passed as function parameter. |
mbed_official | 87:085cde657901 | 70 | (++) Configures the SysTick IRQ priority to the lowest value (0x0F). |
mbed_official | 87:085cde657901 | 71 | (++) Resets the SysTick Counter register. |
mbed_official | 87:085cde657901 | 72 | (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK). |
mbed_official | 87:085cde657901 | 73 | (++) Enables the SysTick Interrupt. |
mbed_official | 87:085cde657901 | 74 | (++) Starts the SysTick Counter. |
mbed_official | 87:085cde657901 | 75 | |
mbed_official | 87:085cde657901 | 76 | (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro |
mbed_official | 87:085cde657901 | 77 | __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the |
mbed_official | 87:085cde657901 | 78 | HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined |
mbed_official | 87:085cde657901 | 79 | inside the stm32f4xx_hal_cortex.h file. |
mbed_official | 87:085cde657901 | 80 | |
mbed_official | 87:085cde657901 | 81 | (+) You can change the SysTick IRQ priority by calling the |
mbed_official | 87:085cde657901 | 82 | HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function |
mbed_official | 87:085cde657901 | 83 | call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function. |
mbed_official | 87:085cde657901 | 84 | |
mbed_official | 87:085cde657901 | 85 | (+) To adjust the SysTick time base, use the following formula: |
mbed_official | 87:085cde657901 | 86 | |
mbed_official | 87:085cde657901 | 87 | Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s) |
mbed_official | 87:085cde657901 | 88 | (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function |
mbed_official | 87:085cde657901 | 89 | (++) Reload Value should not exceed 0xFFFFFF |
