CDC class API functions structure.
This module exposes functions which interact directly with USB device controller hardware.
Definition at line 244 of file usbd_cdcuser.h.
uint32_t GetMemSize |
Function to determine the memory required by the CDC function driver module.
This function is called by application layer before calling pUsbApi->CDC->Init(), to allocate memory used by CDC function driver module. The application should allocate the memory which is accessible by USB controller/DMA controller.
param | Structure containing CDC function driver module initialization parameters. |
Definition at line 257 of file usbd_cdcuser.h.
ErrorCode_t init |
Function to initialize CDC function driver module.
This fuction is called by application layer to initialize CDC function driver module.
hUsb | Handle to the USB device stack. |
param | Structure containing CDC 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 CDC_Write() or CDC_Read() or CDC_Verify() callbacks are not defined. |
ERR_USBD_BAD_INTF_DESC | Wrong interface descriptor is passed. |
ERR_USBD_BAD_EP_DESC | Wrong endpoint descriptor is passed. |
Definition at line 275 of file usbd_cdcuser.h.
ErrorCode_t SendNotification |
Function to initialize CDC function driver module.
This fuction is called by application layer to initialize CDC function driver module.
hUsb | Handle to the USB device stack. |
param | Structure containing CDC 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 CDC_Write() or CDC_Read() or CDC_Verify() callbacks are not defined. |
ERR_USBD_BAD_INTF_DESC | Wrong interface descriptor is passed. |
ERR_USBD_BAD_EP_DESC | Wrong endpoint descriptor is passed. |
