Functions

func GetSerialPorts

func GetSerialPorts(w io.Writer) ([]string, error)

GetSerialPorts scans for serial ports.

Types

type COMport

type COMport interface {
	Open() bool
	Read(buf []byte) (int, error)
	Close() error
}

COMport is the comport interface type to use different COMports.

type PortGoBugSt

type PortGoBugSt struct {
	// contains filtered or unexported fields
}

PortGoBugSt is a serial device trice receiver

func NewCOMPortGoBugSt

func NewCOMPortGoBugSt(w io.Writer, verbose bool, comPortName string) *PortGoBugSt

NewCOMPortGoBugSt creates an instance of a serial device type trice receiver

func (*PortGoBugSt) Close

func (p *PortGoBugSt) Close() error

Close releases port.

func (*PortGoBugSt) Open

func (p *PortGoBugSt) Open() bool

Open initializes the serial receiver.

It opens a serial port.

func (*PortGoBugSt) Read

func (p *PortGoBugSt) Read(buf []byte) (int, error)

Read blocks until (at least) one byte is received from the serial port or an error occurs. It stores data received from the serial port into the provided byte array buffer. The function returns the number of bytes read.
