mbed_official 376:cb4d9db17537 22 This section provide functions allowing to configure the NVIC interrupts (IRQ).
mbed_official 376:cb4d9db17537 23 The Cortex-M0+ exceptions are managed by CMSIS functions.
mbed_official 376:cb4d9db17537 24 (#) Enable and Configure the priority of the selected IRQ Channels.
mbed_official 376:cb4d9db17537 25 The priority can be 0..3.
mbed_official 376:cb4d9db17537 26
mbed_official 376:cb4d9db17537 27 -@- Lower priority values gives higher priority.
mbed_official 376:cb4d9db17537 28 -@- Priority Order:
mbed_official 376:cb4d9db17537 29 (#@) Lowest priority.

mbed_official 376:cb4d9db17537 37 *** How to configure Systick using CORTEX HAL driver ***
mbed_official 376:cb4d9db17537 38 ========================================================
mbed_official 376:cb4d9db17537 39 [..]
mbed_official 376:cb4d9db17537 40 Setup SysTick Timer for time base
mbed_official 376:cb4d9db17537 41
mbed_official 376:cb4d9db17537 42 (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
mbed_official 376:cb4d9db17537 43 is a CMSIS function that:
mbed_official 376:cb4d9db17537 44 (++) Configures the SysTick Reload register with value passed as function parameter.
mbed_official 376:cb4d9db17537 45 (++) Configures the SysTick IRQ priority to the lowest value (0x03).
mbed_official 376:cb4d9db17537 46 (++) Resets the SysTick Counter register.
mbed_official 376:cb4d9db17537 47 (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
mbed_official 376:cb4d9db17537 48 (++) Enables the SysTick Interrupt.
mbed_official 376:cb4d9db17537 49 (++) Starts the SysTick Counter.
mbed_official 376:cb4d9db17537 50
mbed_official 376:cb4d9db17537 51 (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
mbed_official 376:cb4d9db17537 52 __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
mbed_official 376:cb4d9db17537 53 HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
mbed_official 376:cb4d9db17537 54 inside the stm32l0xx_hal_cortex.h file.
mbed_official 376:cb4d9db17537 55
mbed_official 376:cb4d9db17537 56 (+) You can change the SysTick IRQ priority by calling the
mbed_official 376:cb4d9db17537 57 HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
mbed_official 376:cb4d9db17537 58 call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
mbed_official 376:cb4d9db17537 59
mbed_official 376:cb4d9db17537 60 (+) To adjust the SysTick time base, use the following formula:
mbed_official 376:cb4d9db17537 61
mbed_official 376:cb4d9db17537 62 Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
mbed_official 376:cb4d9db17537 63 (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
mbed_official 376:cb4d9db17537 64 (++) Reload Value should not exceed 0xFFFFFF
