Functions

func CheckSum

func CheckSum(checksum []byte) uint8

Types

type Proto

type Proto struct {
	Network io.ReadWriter
}

func New

func New(network io.ReadWriter) *Proto

func (*Proto) ReadData

func (p *Proto) ReadData(ident int, instruction byte) ([]byte, error)

ReadData reads a slice of n bytes from the control table of the given servo ID. Use the bytesToInt function to convert the output to something more useful.

func (*Proto) WriteData

func (p *Proto) WriteData(ident int, instruction byte, data []byte) error
