const EyeToyPrimaryConfig int = 1 // only one configuration

const EyeToyPrimaryEndpoint int = 1

const EyeToyPrimaryInterface int = 0 // only one interface

Types

type EyeToy

type EyeToy struct {
	Context *gousb.Context
	Device  *gousb.Device
	Config  *gousb.Config
}

EyeToy encapsulates known interactions with the Sony EyeToy

func (*EyeToy) Close

func (e *EyeToy) Close()

Close closes out the device connection and context

func (*EyeToy) GetContext

func (e *EyeToy) GetContext()

GetContext acquires a new gousb context and injects it into *EyeToy

func (*EyeToy) GetInterfaceEndpoint

func (e *EyeToy) GetInterfaceEndpoint(alt int) (*gousb.Interface, func(), *gousb.InEndpoint, error)

GetInterfaceEndpoint returns an interface of the given Alternate with a done/Close function as well as the only endpoint available (0x81 1:IN)

iface, done, endpoint, err := eyetoy.GetInterfaceEndpoint(1)
if err != nil {
	// handle error
}
buf := make([]byte, endpoint.Desc.MaxPacketSize)
readBytes, err := endpoint.Read(buf)
done()

func (*EyeToy) Open

func (e *EyeToy) Open() error

Open opens the device with our known VID and PID. It sets autodetach to prevent kernel module interference, then acquires the only known working config for this device and places both inside *EyeToy

e := &EyeToy{}
e.GetContext()
err := e.Open()
if err != nil {
	// handle error
}

func (*EyeToy) ReadEndpoint

func (e *EyeToy) ReadEndpoint(ep *gousb.InEndpoint) (int, []byte, error)

ReadEndpoint reads one Packet from the given endpoint
