mbed_official | 340:28d1f895c6fe | 22 | This section provides functions allowing to configure the NVIC interrupts (IRQ). |
mbed_official | 340:28d1f895c6fe | 23 | The Cortex-M0 exceptions are managed by CMSIS functions. |

mbed_official | 340:28d1f895c6fe | 25 | The priority can be 0..3. |
mbed_official | 340:28d1f895c6fe | 26 | |
mbed_official | 340:28d1f895c6fe | 27 | -@- Lower priority values gives higher priority. |
mbed_official | 340:28d1f895c6fe | 28 | -@- Priority Order: |
mbed_official | 340:28d1f895c6fe | 29 | (#@) Lowest priority. |

mbed_official | 340:28d1f895c6fe | 38 | *** How to configure Systick using CORTEX HAL driver *** |
mbed_official | 340:28d1f895c6fe | 39 | ======================================================== |
mbed_official | 340:28d1f895c6fe | 40 | [..] |
mbed_official | 340:28d1f895c6fe | 41 | Setup SysTick Timer for time base |
mbed_official | 340:28d1f895c6fe | 42 | |
mbed_official | 340:28d1f895c6fe | 43 | (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which |
mbed_official | 340:28d1f895c6fe | 44 | is a CMSIS function that: |
mbed_official | 340:28d1f895c6fe | 45 | (++) Configures the SysTick Reload register with value passed as function parameter. |
mbed_official | 340:28d1f895c6fe | 46 | (++) Configures the SysTick IRQ priority to the lowest value (0x03). |
mbed_official | 340:28d1f895c6fe | 47 | (++) Resets the SysTick Counter register. |
mbed_official | 340:28d1f895c6fe | 48 | (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK). |
mbed_official | 340:28d1f895c6fe | 49 | (++) Enables the SysTick Interrupt. |
mbed_official | 340:28d1f895c6fe | 50 | (++) Starts the SysTick Counter. |
mbed_official | 340:28d1f895c6fe | 51 | |
mbed_official | 340:28d1f895c6fe | 52 | (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro |
mbed_official | 340:28d1f895c6fe | 53 | __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the |
mbed_official | 340:28d1f895c6fe | 54 | HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined |
mbed_official | 340:28d1f895c6fe | 55 | inside the stm32f0xx_hal_cortex.h file. |
mbed_official | 340:28d1f895c6fe | 56 | |
mbed_official | 340:28d1f895c6fe | 57 | (+) You can change the SysTick IRQ priority by calling the |
mbed_official | 340:28d1f895c6fe | 58 | HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function |
mbed_official | 340:28d1f895c6fe | 59 | call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function. |
mbed_official | 340:28d1f895c6fe | 60 | |
mbed_official | 340:28d1f895c6fe | 61 | (+) To adjust the SysTick time base, use the following formula: |
mbed_official | 340:28d1f895c6fe | 62 | |
mbed_official | 340:28d1f895c6fe | 63 | Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s) |
mbed_official | 340:28d1f895c6fe | 64 | (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function |
mbed_official | 340:28d1f895c6fe | 65 | (++) Reload Value should not exceed 0xFFFFFF |
mbed_official | 340:28d1f895c6fe | 66 | |
