DFU class API functions structure.
This module exposes functions which interact directly with USB device controller hardware.
uint32_t USBD_DFU_API_T::GetMemSize |
Function to determine the memory required by the DFU function driver module.
This function is called by application layer before calling pUsbApi->dfu->Init(), to allocate memory used by DFU function driver module. The application should allocate the memory which is accessible by USB controller/DMA controller.
[in] | param | Structure containing DFU function driver module initialization parameters. |
ErrorCode_t USBD_DFU_API_T::init |
Function to initialize DFU function driver module.
This function is called by application layer to initialize DFU function driver module.
[in] | hUsb | Handle to the USB device stack. |
[in,out] | param | Structure containing DFU function driver module initialization parameters. |
LPC_OK | On success |
ERR_USBD_BAD_MEM_BUF | Memory buffer passed is not 4-byte aligned or smaller than required. |
ERR_API_INVALID_PARAM2 | Either DFU_Write() or DFU_Done() or DFU_Read() call-backs are not defined. |
ERR_USBD_BAD_DESC |
|
ERR_USBD_BAD_INTF_DESC | Wrong interface descriptor is passed. |
