Overview

Package link reads from SeggerRTT with the SEGGER app JLinkRTTLogger or with the open source app stRttLogger.exe.

It provides a ReadCloser interface and makes no assumptiona about the delivered data. It is also agnostic concerning the RTT channel and other setup parameters.

Types

type Device

type Device struct {
	Exec string // linkBinary is the RTT logger executable .
	Lib  string // linkDynLib is the RTT used dynamic library name.

	Err  error
	Done chan bool
	// contains filtered or unexported fields
}

Device is the RTT logger reader interface.

func NewDevice

func NewDevice(port, arguments string) *Device

NewDevice creates an instance of RTT ReadCloser of type Port. The Args string is used as parameter string. See SEGGER UM08001_JLink.pdf for details.

func (*Device) Close

func (p *Device) Close() error

Close is part of the exported interface io.ReadCloser. It ends the connection.

func (*Device) ErrorFatal

func (p *Device) ErrorFatal()

ErrorFatal ends in osExit(1) if p.Err not nil.

func (*Device) Open

func (p *Device) Open() error

Open starts the RTT logger command with a temporary logfile. The temporary logfile is opened for reading.

func (*Device) Read

func (p *Device) Read(b []byte) (int, error)

Read() is part of the exported interface io.ReadCloser. It reads a slice of bytes.
