go-serial

This is a package that allows you to read from and write to serial ports in Go.

OS support

Currently this package works only on OS X, Linux and Windows. It could probably be ported to other Unix-like platforms simply by updating a few constants; get in touch if you are interested in helping and have hardware to test with.

Installation

Simply use

go get

go get github.com/jacobsa/go-serial/serial

To update later:

go get -u github.com/jacobsa/go-serial/serial

Use

Set up a

serial.OpenOptions

serial.Open

    import "fmt"
    import "log"
    import "github.com/jacobsa/go-serial/serial"

...

// Set up options.
options := serial.OpenOptions{
  PortName: "/dev/tty.usbserial-A8008HlV",
  BaudRate: 19200,
  DataBits: 8,
  StopBits: 1,
  MinimumReadSize: 4,
}

// Open the port.
port, err := serial.Open(options)
if err != nil {
  log.Fatalf("serial.Open: %v", err)
}

// Make sure to close it later.
defer port.Close()

// Write 4 bytes to the port.
b := []byte{0x00, 0x01, 0x02, 0x03}
n, err := port.Write(b)
if err != nil {
  log.Fatalf("port.Write: %v", err)
}

fmt.Println("Wrote", n, "bytes.")
