STM32L151 STOP模式功耗过高

雪叶龙提问时间：2019-10-20 14:34 /

咨询下，哪位大神做过stop模式，现在程序电流很大，进入STOP后电流有800UA左右。有经验的能帮忙看下程序哪有问题吗，感激不尽int main(void)
{

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
SystemInit();
RTC_Config();

//RCC_LSEConfig(RCC_LSE_OFF);
Led_Init();
delay_init();
GPIO_DeInit(GPIOA);
GPIO_DeInit(GPIOC);
   DisableDBGStopMode();
COMP_DeInit();
PWR_PVDCmd(DISABLE);

  /* Add your application code here
   */
   ADC_DeInit(ADC1);
  /* Infinite loop */
  while (1)
  {
   /* Enable Wakeup Counter */
RTC_WakeUpCmd(ENABLE);
gpio_lowpower_fun();

/* Enter Stop Mode */
PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI);
}
}

进入低功耗前调用函数
void gpio_lowpower_fun(void)
{
GPIO_InitTypeDef GPIO_InitStructure;

RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOA, ENABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOB, ENABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOC, ENABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOD, ENABLE);

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_All;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_400KHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_OType = GPIO_OType_OD;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_DOWN;

GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_Init(GPIOC, &GPIO_InitStructure);
GPIO_Init(GPIOD, &GPIO_InitStructure);

RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOA, DISABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOB, DISABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOC, DISABLE);
RCC_AHBPeriphResetCmd(RCC_AHBPeriph_GPIOD, DISABLE);
}
