Exception handling

6.2

Custom Handlers

One way to generate templates of Handler functions is to use STM32CubeMX.

In Configuration -> NVIC Configuration -> Code Generation, use Generate IRQ handler

tick boxes as shown in Figure 31.

Figure 31. Asking for Handler code generation

When Non maskable interrupt and Hard fault interrupt are selected, the following code is

generated:

void NMI_Handler(void)

{

/* USER CODE BEGIN NonMaskableInt_IRQn 0 */

/* USER CODE END NonMaskableInt_IRQn 0 */

/* USER CODE BEGIN NonMaskableInt_IRQn 1 */

/* USER CODE END NonMaskableInt_IRQn 1 */

}

/**

* @brief This function handles Hard fault interrupt.

void HardFault_Handler(void)

{

/* USER CODE BEGIN HardFault_IRQn 0 */

/* USER CODE END HardFault_IRQn 0 */

while (1)

{

}

/* USER CODE BEGIN HardFault_IRQn 1 */

/* USER CODE END HardFault_IRQn 1 */

}
