What hardware supports Go language?

With the continuous development and popularity of Go language, more and more hardware devices have begun to support the development of Go language. This provides developers with more options, allowing them to take advantage of the simplicity, efficiency, and powerful features of the Go language to develop hardware-related applications. The following will introduce some hardware currently supporting the Go language and specific code examples.

1. Raspberry Pi
   The Raspberry Pi is a popular small single-board computer that is widely used in the Internet of Things, embedded systems and other fields. By installing the Go language development environment, we can use the GPIO pins of the Raspberry Pi for hardware development. The following is a simple example code for controlling LED lights through Raspberry Pi:

package main

import (
    "fmt"
    "os"
    "os/signal"
    "time"

    "github.com/stianeikeland/go-rpio"
)

func main() {
    if err := rpio.Open(); err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    defer rpio.Close()

    pin := rpio.Pin(18)
    pin.Output()

    c := make(chan os.Signal, 1)
    signal.Notify(c, os.Interrupt)
    go func() {
        for _ = range c {
            pin.Low()
        }
    }()

    for {
        pin.Toggle()
        time.Sleep(time.Second)
    }
}

The above code demonstrates how to use the third-party library "stianeikeland/go-rpio" to control the GPIO pin on Raspberry Pi. An example of a pin that realizes simple hardware interaction by controlling the on and off of LED lights.

2. Arduino
   Arduino is an open source hardware platform that is widely used in the Internet of Things, robots, sensors and other fields. Through Arduino's Firmata library, we can easily communicate with Arduino in the Go language. The following is a simple example code for controlling an Arduino car through the Go language:

package main

import (
    "fmt"
    "time"

    "github.com/tarm/serial"
)

func main() {
    c := &serial.Config{Name: "COM3", Baud: 9600}
    s, err := serial.OpenPort(c)
    if err != nil {
        fmt.Println(err)
        return
    }

    for {
        _, err := s.Write([]byte("forward"))
        if err != nil {
            fmt.Println(err)
            return
        }
        time.Sleep(2 * time.Second)

        _, err = s.Write([]byte("stop"))
        if err != nil {
            fmt.Println(err)
            return
        }
        time.Sleep(2 * time.Second)
    }
}

The above code demonstrates how to use the "tarm/serial" library to communicate with Arduino through the serial port in the Go language to achieve control. Car forward and stop functions.

In addition to Raspberry Pi and Arduino, there are many other hardware devices that can also support Go language development, such as ESP8266/ESP32, BeagleBone, etc. By learning and exploring the relevant documentation and libraries of these hardware devices, developers can better take advantage of the Go language to implement various innovative hardware applications.

In general, there are many types of hardware that support the Go language. Developers can choose the appropriate hardware platform according to their own needs and develop based on the above code examples. I hope this article can be helpful to Go language developers who want to engage in hardware development.
