The UDC provides a high-level abstraction of the usb device.
You can use these functions to control the main device state (start/attach/wakeup).
The following USB Device configuration must be included in the conf_usb.h file of the application.
USB_DEVICE_VENDOR_ID (Word)
Vendor ID provided by USB org (ATMEL 0x03EB).
USB_DEVICE_PRODUCT_ID (Word)
Product ID (Referenced in usb_atmel.h).
USB_DEVICE_MAJOR_VERSION (Byte)
Major version of the device
USB_DEVICE_MINOR_VERSION (Byte)
Minor version of the device
USB_DEVICE_MANUFACTURE_NAME (string)
ASCII name for the manufacture
USB_DEVICE_PRODUCT_NAME (string)
ASCII name for the product
USB_DEVICE_SERIAL_NAME (string)
ASCII name to enable and set a serial number
USB_DEVICE_POWER (Numeric)
(unit mA) Maximum device power
USB_DEVICE_ATTR (Byte)
USB attributes available:
USB_DEVICE_LOW_SPEED (Only defined)
Force the USB Device to run in low speed
USB_DEVICE_HS_SUPPORT (Only defined)
Authorize the USB Device to run in high speed
USB_DEVICE_MAX_EP (Byte)
Define the maximum endpoint number used by the USB Device.
This one is already defined in UDI default configuration. Ex:
