小歆-2051663 发表于 2020-10-26 11:33 这个要根据你的项目情况，关闭不需要外设。 大佬您好 我按照您说的将所有的GPIO端口关闭了，功耗的确降下来了 GPIO_InitTypeDef GPIO_InitStruct; __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_DISABLE(); __HAL_RCC_GPIOC_CLK_DISABLE(); __HAL_RCC_GPIOD_CLK_DISABLE(); __HAL_RCC_GPIOE_CLK_DISABLE(); __HAL_RCC_GPIOF_CLK_DISABLE(); __HAL_RCC_GPIOG_CLK_DISABLE(); __HAL_RCC_GPIOH_CLK_DISABLE(); GPIO_InitStruct.Mode = GPIO_MODE_ANALOG; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Pin = GPIO_PIN_All; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); HAL_GPIO_Init(GPIOB, &GPIO_InitStruct); HAL_GPIO_Init(GPIOC, &GPIO_InitStruct); HAL_GPIO_Init(GPIOD, &GPIO_InitStruct); HAL_GPIO_Init(GPIOE, &GPIO_InitStruct); HAL_GPIO_Init(GPIOF, &GPIO_InitStruct); HAL_GPIO_Init(GPIOG, &GPIO_InitStruct); HAL_GPIO_Init(GPIOH, &GPIO_InitStruct); __HAL_RCC_GPIOA_CLK_DISABLE(); __HAL_RCC_GPIOB_CLK_DISABLE(); __HAL_RCC_GPIOC_CLK_DISABLE(); __HAL_RCC_GPIOD_CLK_DISABLE(); __HAL_RCC_GPIOE_CLK_DISABLE(); __HAL_RCC_GPIOF_CLK_DISABLE(); __HAL_RCC_GPIOG_CLK_DISABLE(); __HAL_RCC_GPIOH_CLK_DISABLE();复制代码 但是发现ADC测量不准了 这个应该如何调整唤醒后的操作为 HAL_RTCEx_DeactivateWakeUpTimer(&RTCHandle);//清除RTC计时器 HAL_RTCEx_SetWakeUpTimer_IT(&RTCHandle, 10000, RTC_WAKEUPCLOCK_RTCCLK_DIV16); HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI); SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_ADC2_Init(); MX_SPI2_Init(); MX_TIM2_Init(); MX_TIM8_Init();复制代码也按照cubemx的初始化了GPIO
