bogdanm | 0:9b334a45a8ff | 64 | ======================================================== |
bogdanm | 0:9b334a45a8ff | 65 | [..] |
bogdanm | 0:9b334a45a8ff | 66 | Setup SysTick Timer for 1 msec interrupts. |
bogdanm | 0:9b334a45a8ff | 67 | |
bogdanm | 0:9b334a45a8ff | 68 | (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which |
bogdanm | 0:9b334a45a8ff | 69 | is a CMSIS function that: |
bogdanm | 0:9b334a45a8ff | 70 | (++) Configures the SysTick Reload register with value passed as function parameter. |
bogdanm | 0:9b334a45a8ff | 71 | (++) Configures the SysTick IRQ priority to the lowest value (0x0F). |
bogdanm | 0:9b334a45a8ff | 72 | (++) Resets the SysTick Counter register. |
bogdanm | 0:9b334a45a8ff | 73 | (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK). |
bogdanm | 0:9b334a45a8ff | 74 | (++) Enables the SysTick Interrupt. |
bogdanm | 0:9b334a45a8ff | 75 | (++) Starts the SysTick Counter. |
bogdanm | 0:9b334a45a8ff | 76 | |
bogdanm | 0:9b334a45a8ff | 77 | (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro |
bogdanm | 0:9b334a45a8ff | 78 | __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the |
bogdanm | 0:9b334a45a8ff | 79 | HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined |
bogdanm | 0:9b334a45a8ff | 80 | inside the stm32l1xx_hal_cortex.h file. |
bogdanm | 0:9b334a45a8ff | 81 | |
bogdanm | 0:9b334a45a8ff | 82 | (+) You can change the SysTick IRQ priority by calling the |
bogdanm | 0:9b334a45a8ff | 83 | HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function |
bogdanm | 0:9b334a45a8ff | 84 | call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function. |
bogdanm | 0:9b334a45a8ff | 85 | |
bogdanm | 0:9b334a45a8ff | 86 | (+) To adjust the SysTick time base, use the following formula: |
bogdanm | 0:9b334a45a8ff | 87 | |
bogdanm | 0:9b334a45a8ff | 88 | Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s) |
bogdanm | 0:9b334a45a8ff | 89 | (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function |
bogdanm | 0:9b334a45a8ff | 90 | (++) Reload Value should not exceed 0xFFFFFF |
