Documentation

Overview

Package enumerator is a golang cross-platform library for USB serial port discovery.

This library has been tested on Linux, Windows and Mac and uses specific OS services to enumerate USB PID/VID, in particular on MacOSX the use of cgo is required in order to access the IOKit Framework. This means that the library cannot be easily cross compiled for darwin/* targets.

Types

type PortDetails

type PortDetails struct {
	Name         string
	IsUSB        bool
	VID          string
	PID          string
	SerialNumber string

	// Product is an OS-dependent string that describes the serial port, it may
	// be not always available and it may be different across OS.
	Product string
}

PortDetails contains detailed information about USB serial port. Use GetDetailedPortsList function to retrieve it.

func GetDetailedPortsList

func GetDetailedPortsList() ([]*PortDetails, error)

GetDetailedPortsList retrieve ports details like USB VID/PID. Please note that this function may not be available on all OS: in that case a FunctionNotImplemented error is returned.

Example

package main

import (
	"fmt"
	"log"

	"github.com/calliday/go-serial/enumerator"
)

func main() {
	ports, err := enumerator.GetDetailedPortsList()
	if err != nil {
		log.Fatal(err)
	}
	if len(ports) == 0 {
		fmt.Println("No serial ports found!")
		return
	}
	for _, port := range ports {
		fmt.Printf("Found port: %s\n", port.Name)
		if port.IsUSB {
			fmt.Printf("   USB ID     %s:%s\n", port.VID, port.PID)
			fmt.Printf("   USB serial %s\n", port.SerialNumber)
		}
	}
}

type PortEnumerationError

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

PortEnumerationError is the error type for serial ports enumeration

func (PortEnumerationError) Error

func (e PortEnumerationError) Error() string

Error returns the complete error code with details on the cause of the error
