Implementation Guidelines

The task body is usually implemented as an infinite loop. The task should perform the following steps:

  1. Call USBD_StorageRefreshTaskHandler() function defined in the µC/FS storage layer. This function implements the removable media insertion/removable detection..

  2. Delay for a certain period of time. This delay is configurable by you through the configuration constant, USBD_MSC_CFG_DEV_POLL_DLY_mS. Refer to MSC General Configuration for more details about this constant.
