[参考译文] MSPM0C1104：如何设置 GPIO 并生成中断？

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1426344/mspm0c1104-how-to-setup-gpio-and-generate-interrupt

工具与软件：

标题相同、现在我要尝试捕获来自 PA22的中断

但如果我将上升沿输出到 PA22、我将找不到任何中断。

下面是我的代码,有任何专家可以给我一些建议. 非常感谢。

/* Defines for DC: GPIOA.22 with pinCMx 23 on package pin 22 */
#define BAMBOO_GPIO_DC_PIN                                     (DL_GPIO_PIN_22)
#define BAMBOO_GPIO_DC_IOMUX                                    (IOMUX_PINCM23)

/* Defines for LED_RED: GPIOA.2 with pinCMx 3 on package pin 8 */
#define BAMBOO_GPIO_LED_RED_PIN                                  (DL_GPIO_PIN_2)
#define BAMBOO_GPIO_LED_RED_IOMUX                                 (IOMUX_PINCM3)

int main(void)
{
    SYSCFG_DL_init();

// Sleep test...PK 20241017+
    // set DC to input...PK 20241017+
    DL_GPIO_enableGlobalFastWake(GPIOA);

    DL_GPIO_initDigitalInputFeatures(BAMBOO_GPIO_DC_IOMUX,
         DL_GPIO_INVERSION_DISABLE, DL_GPIO_RESISTOR_PULL_UP,
         DL_GPIO_HYSTERESIS_DISABLE, DL_GPIO_WAKEUP_ENABLE);

    DL_GPIO_setUpperPinsPolarity(GPIOA, DL_GPIO_PIN_22_EDGE_RISE_FALL);
    DL_GPIO_clearInterruptStatus(GPIOA, BAMBOO_GPIO_DC_PIN);
    DL_GPIO_enableInterrupt(GPIOA, BAMBOO_GPIO_DC_PIN);

    NVIC_EnableIRQ(GPIOA_INT_IRQn);

    DL_SYSCTL_setPowerPolicySTANDBY0();

    while(1){
        __WFI();
    }

}

void GPIOA_IRQHandler(void)
{
    /* If SW is high, turn the LED off */
    if (DL_GPIO_readPins(
            BAMBOO_GPIO_PORT, BAMBOO_GPIO_DC_PIN)) {
        DL_GPIO_setPins(BAMBOO_GPIO_PORT, BAMBOO_GPIO_LED_RED_PIN);
    }
    /* Otherwise, turn the LED on */
    else {
        DL_GPIO_clearPins(BAMBOO_GPIO_PORT, BAMBOO_GPIO_LED_RED_PIN);
    }
}
