Posted on September 16, 2014 at 13:54I am trying to use multiple interupts on my nucleo board. I have used the cube hal. My problem is that I dont get the interrupts generated on the PB0 pin, but the PB1 works ok.
I have tried to do the intialization in different order and it seems like it works better, but I dont understand why the HAL needs calls in a specific order.
My code to initialize the interrupts are based on the GPIO_EXTI example:
static void EXTI_Config(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
/* Enable GPIOB clock */
__GPIOB_CLK_ENABLE();
/* Configure PB0 pin */
GPIO_InitStructure.Mode = GPIO_MODE_IT_FALLING;
GPIO_InitStructure.Pull = GPIO_PULLUP;
GPIO_InitStructure.Pin = GPIO_PIN_0;
GPIO_InitStructure.Speed = GPIO_SPEED_FAST;
HAL_GPIO_Init(GPIOB, &GPIO_InitStructure);
/* Configure PB1 pin */
GPIO_InitStructure.Mode = GPIO_MODE_IT_FALLING;
GPIO_InitStructure.Pull = GPIO_PULLUP;
GPIO_InitStructure.Pin = GPIO_PIN_1;
GPIO_InitStructure.Speed = GPIO_SPEED_FAST;
HAL_GPIO_Init(GPIOB, &GPIO_InitStructure);
/* Enable and set EXTI Interrupt to the lowest priority */
HAL_NVIC_SetPriority(EXTI0_1_IRQn, 3, 0);
HAL_NVIC_EnableIRQ(EXTI0_1_IRQn);
}
