Function Example

sers_test.go:16–25

This program opens a serial port, configurable by changing portname below and configures it for 57600 baud, 8 data bits, no parity bit, 1 stop bit, no handshaking. It then reads up to 128 bytes from the serial port, with a timeout of 1 second and prints the received bytes to stdout.

()

// port, with a timeout of 1 second and prints the received
// bytes to stdout.
func Example() {
	portname := "/dev/ttyUSB0"
	rb, err := readFirstBytesFromPort(portname)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("got %d bytes from %s:\n%s", len(rb), portname,
		hex.Dump(rb))
}

func readFirstBytesFromPort(fn string) ([]byte, error) {
	sp, err := sers.Open(fn)
