Header file for Descriptors.c.
| #define CDC_NOTIFICATION_EPADDR (ENDPOINT_DIR_IN | 2) |
Endpoint address of the CDC device-to-host notification IN endpoint.
| #define CDC_NOTIFICATION_EPSIZE 8 |
Size in bytes of the CDC device-to-host notification IN endpoint.
| #define CDC_RX_EPADDR (ENDPOINT_DIR_OUT | 4) |
Endpoint address of the CDC host-to-device data OUT endpoint.
| #define CDC_TX_EPADDR (ENDPOINT_DIR_IN | 3) |
Endpoint address of the CDC device-to-host data IN endpoint.
| #define CDC_TXRX_EPSIZE 16 |
Size in bytes of the CDC data IN and OUT endpoints.
Enum for the device interface descriptor IDs within the device. Each interface descriptor should have a unique ID index associated with it, which can be used to refer to the interface from other descriptors.
| Enumerator | |
|---|---|
| INTERFACE_ID_CDC_CCI | CDC CCI interface descriptor ID |
| INTERFACE_ID_CDC_DCI | CDC DCI interface descriptor ID |
| enum StringDescriptors_t |
Enum for the device string descriptor IDs within the device. Each string descriptor should have a unique ID index associated with it, which can be used to refer to the string from other descriptors.
| Enumerator | |
|---|---|
| STRING_ID_Language | Supported Languages string descriptor ID (must be zero) |
| STRING_ID_Manufacturer | Manufacturer string ID |
| STRING_ID_Product | Product string ID |

This function is called by the library when in device mode, and must be overridden (see library "USB Descriptors" documentation) by the application code so that the address and size of a requested descriptor can be given to the USB library. When the device receives a Get Descriptor request on the control endpoint, this function is called so that the descriptor details can be passed back and the appropriate descriptor sent back to the USB host.
