Detailed Description

USB device support class data.

Field Documentation

desc

void* usbd_class_data::desc

Pointer to a class implementation descriptor that should end with a nil descriptor (bLength = 0 and bDescriptorType = 0).

ep_active

uint32_t usbd_class_data::ep_active

Bitmap of the enabled endpoints of the instance.

The IN endpoints are mapped in the upper halfword.

ep_assigned

uint32_t usbd_class_data::ep_assigned

Bitmap of all endpoints assigned to the instance.

The IN endpoints are mapped in the upper halfword.

iface_bm

uint32_t usbd_class_data::iface_bm

Bitmap of the bInterfaceNumbers of the class instance.

priv

void* usbd_class_data::priv

Pointer to private data.

state

atomic_t usbd_class_data::state

Variable to store the state of the class instance.

uds_ctx

struct usbd_contex* usbd_class_data::uds_ctx

Pointer to USB device stack context structure.

v_reqs

const struct usbd_cctx_vendor_req* usbd_class_data::v_reqs

Supported vendor request table, can be NULL.
