Defines

CY_USB_DEV_MW_VERSION_MAJOR¶: USB Device Middleware major version.

CY_USB_DEV_MW_VERSION_MINOR¶: USB Device Middleware minor version.

CY_USB_DEV_ID¶: USB Device Middleware identifier.

CY_USB_DEV_NUM_INTERFACES_MAX¶: Maximum number of interfaces (this equals to the maximum number of hardware endpoints where each interface has at least one endpoint).

CY_USB_DEV_EP0_PACKET_SIZE¶: USBFS Device endpoint 0 packet size.

CY_USB_DEV_SN_STRING_LENGTH¶: Length of serial string number generated from silicon ID.

CY_USB_DEV_SN_STRING_DESR_LENGTH¶: Length of serial string number.

CY_USB_DEV_WAIT_FOREVER¶: Timeout value that defines wait forever.

CY_USB_DEV_ALLOC_ENDPOINT_BUFFER(buf, size)¶

Allocates static buffer for data endpoint.

The size parameter must be a constant. The allocated buffer is aligned on a 2 byte boundary. An odd buffer size is converted to even consuming 1 extra byte. The application must discard this extra byte. This manipulation is needed to support different 8-bit and 16-bit hardware buffer access types in the driver (See Hardware Buffer Access section of the USBFS driver for more information).

CY_USB_DEV_DIR_HOST_TO_DEVICE¶: Transfer direction from Host to Device (setup packet)

CY_USB_DEV_DIR_DEVICE_TO_HOST¶: Transfer direction from Device to Host (setup packet)

CY_USB_DEV_STANDARD_TYPE¶: Standard request type (setup packet)

CY_USB_DEV_CLASS_TYPE¶: Class-specific request type (setup packet)

CY_USB_DEV_VENDOR_TYPE¶: Vendor-specific request type (setup packet)

CY_USB_DEV_RESERVED_TYPE¶: Reserved request type (setup packet)

CY_USB_DEV_RECIPIENT_DEVICE¶: Request recipient device (setup packet)

CY_USB_DEV_RECIPIENT_INTERFACE¶: Request recipient interface (setup packet)

CY_USB_DEV_RECIPIENT_ENDPOINT¶: Request recipient endpoint (setup packet)

CY_USB_DEV_RECIPIENT_OTHER¶: Request recipient other (setup packet)

CY_USB_DEV_RQST_GET_STATUS¶: GET_STATUS standard request.

CY_USB_DEV_RQST_CLEAR_FEATURE¶: CLEAR_FEATURE standard request.

CY_USB_DEV_RQST_SET_FEATURE¶: SET_FEATURE standard request.
