What hardware is the Go language suitable for?

Go language, as an efficient, fast and easy-to-use programming language, has gradually been widely used in various fields. Among them, as a statically typed language, Go language also has excellent performance in handling hardware programming. This article will analyze some hardware suitable for Go language and give specific code examples.

1. Raspberry Pi

Raspberry Pi is a popular single-board computer. Due to its low cost, compactness, and ease of use, It is widely used in embedded systems, Internet of Things and education fields. The Go language has powerful concurrent programming capabilities and is suitable for hardware control on the Raspberry Pi.

The following is a simple example code for using Go language to control the Raspberry Pi GPIO (general purpose input and output):

package main

import (
    "fmt"
    "github.com/stianeikeland/go-rpio"
    "time"
)

func main() {
    err := rpio.Open()
    if err != nil {
        fmt.Println(err)
        return
    }
    defer rpio.Close()

    pin := rpio.Pin(18) // 使用BCM编号18的引脚
    pin.Output()

    for {
        pin.Toggle() // 切换引脚状态
        time.Sleep(time.Second)
    }
}

2. Arduino

Arduino is An open source hardware platform that provides a range of development boards and an easy-to-use integrated development environment (IDE) that is widely used in prototyping and education. With the cross-compilation capability of the Go language, we can write Go code on Arduino to achieve hardware control.

The following is a simple example code for using Go language to control LED lights on Arduino:

package main

import (
    "os"
    "time"

    "github.com/tarm/serial"
)

func main() {
    c := &serial.Config{Name: "/dev/ttyUSB0", Baud: 9600}
    s, err := serial.OpenPort(c)
    if err != nil {
        os.Exit(1)
    }
    defer s.Close()

    buf := make([]byte, 1)

    for {
        buf[0] = '1'
        s.Write(buf)
        time.Sleep(time.Second)

        buf[0] = '0'
        s.Write(buf)
        time.Sleep(time.Second)
    }
}

The above introduces the example code for using Go language for hardware programming on Raspberry Pi and Arduino. Through these examples, we can see that Go language, as an efficient, concise and easy-to-use programming language, is very suitable for hardware programming, providing developers with more flexibility and convenience. I hope this article will help readers understand the application of Go language in hardware programming.
