A practical guide to building embedded systems based on Golang

A practical guide to building embedded systems with Go: choosing the right hardware based on processor architecture, memory, and peripherals. Set up Go compiler, cross compiler and integrated development environment. Write the application code (such as the code to blink the LED in the example). Use a cross-compiler to compile the code and load it into the embedded device. Leverage Go's debugging tools to troubleshoot your code.

A practical guide to building embedded systems based on Go

Introduction
Go is a Popular programming language known for its simplicity, concurrency, and cross-platform compatibility. It is growing in popularity in embedded systems development as it provides a powerful set of tools and libraries to simplify the development process. This guide is intended to provide a practical guide for Go developers building embedded systems.

Choose the right hardware
For embedded systems, choosing the right hardware is crucial. The following factors need to be considered:

• Processor architecture: 32-bit or 64-bit
• Memory: Minimum memory required by the application Quantity
• Peripherals:Required sensors, actuators, and other interfaces

Set up the development environment
Build the embed using Go The following tools need to be set up for the system:

• Golang compiler: https://go.dev/dl/
• Go compiled cross-compiler (for specific architectures): https: //crosscompiler-arm.github.io/
• Integrated development environment (IDE): such as Visual Studio Code or GoLand

Actual case
below It is a practical case showing how to use Go to build a simple embedded LED flashing application:

package main

import (
    "machine"
    "time"
)

func main() {
    led := machine.LED
    led.Configure(machine.PinConfig{Mode: machine.PinOutput})

    for {
        led.High()
        time.Sleep(500 * time.Millisecond)
        led.Low()
        time.Sleep(500 * time.Millisecond)
    }
}

Compile and load
Compile the code using a cross-compiler:

go build -o led-blink.elf led-blink.go

Then use the programmer to load the binary file to the embedded device.

Debugging
Go provides a range of debugging tools for finding and fixing errors in your code. Higher level debugging can be done using an external debugger such as gdb.

Conclusion
Building embedded systems with Go offers many advantages, including concurrency, cross-platform compatibility, and a rich library ecosystem. This guide provides the basics of building embedded systems and demonstrates a simple practical example. By following this guide, Go developers can start creating their own embedded applications.
