DFU class API functions structure.
This module exposes functions which interact directly with USB device controller hardware.
Definition at line 183 of file usbd_dfuuser.h.
uint32_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.
param | Structure containing DFU function driver module initialization parameters. |
Definition at line 196 of file usbd_dfuuser.h.
ErrorCode_t init |
Function to initialize DFU function driver module.
This function is called by application layer to initialize DFU function driver module.
hUsb | Handle to the USB device stack. |
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() callbacks are not defined. |
ERR_USBD_BAD_DESC |
|
ERR_USBD_BAD_INTF_DESC | Wrong interface descriptor is passed. |
