CC1310中的gpio中断问题(RTOS)

单独例程可以正常运行,可是集成到adc的例程后就不响应了,请问何故?

代码如下:

void gpioButtonFxn10(uint_least8_t index)
{/* Clear the GPIO interrupt and toggle an LED */GPIO_toggle(Board_GPIO_LED1);
}
/*

/***** Function definitions *****/
void NodeTask_init(void)
{
GPIO_setConfig(Board_GPIO_BUTTON0, GPIO_CFG_IN_PU | GPIO_CFG_IN_INT_FALLING);/* Turn on user LED */GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_ON);/* install Button callback */GPIO_setCallback(Board_GPIO_BUTTON0, gpioButtonFxn10);/* Enable interrupts */GPIO_enableInt(Board_GPIO_BUTTON0);/* Create event used internally for state changes */Event_Params eventParam;Event_Params_init(&eventParam);Event_construct(&nodeEvent, &eventParam);nodeEventHandle = Event_handle(&nodeEvent);/* Create the node task */Task_Params_init(&nodeTaskParams);nodeTaskParams.stackSize = NODE_TASK_STACK_SIZE;nodeTaskParams.priority = NODE_TASK_PRIORITY;nodeTaskParams.stack = &nodeTaskStack;Task_construct(&nodeTask, nodeTaskFunction, &nodeTaskParams, NULL);
}


static void nodeTaskFunction(UArg arg0, UArg arg1)
{/* Open LED pins */ledPinHandle = PIN_open(&ledPinState, pinTable);if (!ledPinHandle){System_abort("Error initializing board 3.3V domain pins\n");}/* Start the SCE ADC task with 1s sample period and reacting to change in ADC value. */SceAdc_init(0x00010000/30, NODE_ADCTASK_REPORTINTERVAL_FAST, NODE_ADCTASK_CHANGE_MASK);SceAdc_setReportInterval(200,150);SceAdc_registerAdcCallback(adcCallback);SceAdc_start();while(1) {/* Wait for event */uint32_t events = Event_pend(nodeEventHandle, 0, NODE_EVENT_ALL, BIOS_WAIT_FOREVER);/* If new ADC value, send this data */if (events & NODE_EVENT_NEW_ADC_VALUE) {/* Toggle activity LED *///PIN_setOutputValue(ledPinHandle, NODE_ACTIVITY_LED,!PIN_getOutputValue(NODE_ACTIVITY_LED));/* Send ADC value to concentrator */NodeRadioTask_sendAdcData(&latestAdcValue);}}
}

void adcCallback(struct adc_values *currentadcvalues)
{/* Save latest value */latestAdcValue = *currentadcvalues;/* Post event */Event_post(nodeEventHandle, NODE_EVENT_NEW_ADC_VALUE);
}

你是说gpio进不了中断吗?Gpio的引脚和ADC有没有冲突?
