Functions | |
void | HAL_NVIC_SetPriorityGrouping (uint32_t PriorityGroup) |
Set the priority grouping field (pre-emption priority and subpriority) using the required unlock sequence. | |
void | HAL_NVIC_SetPriority (IRQn_Type IRQn, uint32_t PreemptPriority, uint32_t SubPriority) |
Set the priority of an interrupt. | |
void | HAL_NVIC_EnableIRQ (IRQn_Type IRQn) |
Enable a device specific interrupt in the NVIC interrupt controller. | |
void | HAL_NVIC_DisableIRQ (IRQn_Type IRQn) |
Disable a device specific interrupt in the NVIC interrupt controller. | |
void | HAL_NVIC_SystemReset (void) |
Initiate a system reset request to reset the MCU. | |
uint32_t | HAL_SYSTICK_Config (uint32_t TicksNumb) |

void | HAL_SYSTICK_CLKSourceConfig (uint32_t CLKSource) |
Configure the SysTick clock source. | |
void | HAL_SYSTICK_IRQHandler (void) |
Handle SYSTICK interrupt request. | |
__weak void | HAL_SYSTICK_Callback (void) |
