CC1352P: CC1352P1 LaunchPad 进入standby后无法用按键唤醒

ea skk

Part Number: CC1352P

代码仅做最简进入standby后按键唤醒，测试用外部供电仅能进入休眠，无法唤醒，调试器供电也一样，有没有大佬知道怎么解决

#include <stdint.h>
#include <stdbool.h>
#include <ti/drivers/Power.h>
#include <ti/drivers/power/PowerCC26XX.h>
#include <ti/drivers/GPIO.h>
#include "ti_drivers_config.h"



volatile bool isKeyWakeup = false;
#define AON_WAKEUP_PIN 14  
#define LED_PIN 6       


void keyWakeupCallback(uint_least8_t index)
{
    isKeyWakeup = true;
    GPIO_clearInt(index);
}


void initWakeupSystem(void)
{
    Power_init();
    Power_releaseConstraint(PowerCC26XX_DISALLOW_STANDBY);
    Power_setPolicy(PowerCC26XX_standbyPolicy);
    GPIO_init();
    GPIO_PinConfig wakeupConfig = GPIO_CFG_IN_PU | GPIO_CFG_IN_INT_FALLING | GPIO_CFG_INT_ENABLE | GPIO_CFG_SHUTDOWN_WAKE_LOW;
    GPIO_setConfig(AON_WAKEUP_PIN, wakeupConfig);
    GPIO_setCallback(AON_WAKEUP_PIN, keyWakeupCallback);   
    GPIO_setConfig(LED_PIN, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
}


void *mainThread(void *arg0)
{
    initWakeupSystem();

    while(1)
    {
        isKeyWakeup = false;
       
        Power_sleep(PowerCC26XX_STANDBY);
        
       
        if (isKeyWakeup)
        {
            GPIO_toggle(LED_PIN);
          
            for (volatile uint32_t i=0; i<200000; i++);
        }
    }
}

你好，我用示例测试了，可以正常控制亮灭，只是没有消抖会有一些抖动现象
