We are Doing the Low Power Mode and try to consume less power during the Sleep Mode.Because of that Reason we We are doing deinit of the USB.So ,after deinitilization we are getting the less current consumption.
But issue is coming when device wake-up after sleep ,we are Initilizing the USB after wake-up But its not working.
Below is the Two function which is i am using for init and deinit of USB
We are using USB as Virtual Com Port in configuration in MxCubeIDE.
//Init function
void MX_USB_DEVICE_Init(void)
{
/* USER CODE BEGIN USB_DEVICE_Init_PreTreatment */
/* USER CODE END USB_DEVICE_Init_PreTreatment */
/* Init Device Library, add supported class and start the library. */
if (USBD_Init(&hUsbDeviceFS, &FS_Desc, DEVICE_FS) != USBD_OK)
{
Error_Handler();
}
if (USBD_RegisterClass(&hUsbDeviceFS, &USBD_CDC) != USBD_OK)
{
Error_Handler();
}
if (USBD_CDC_RegisterInterface(&hUsbDeviceFS, &USBD_Interface_fops_FS) != USBD_OK)
{
Error_Handler();
}
if (USBD_Start(&hUsbDeviceFS) != USBD_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USB_DEVICE_Init_PostTreatment */
/* USER CODE END USB_DEVICE_Init_PostTreatment */
}
//Deinit function
void MX_USB_DEVICE_DeInit(void)
{
USBD_DeInit(&hUsbDeviceFS);
}
