Embedded Go Programming

Embedded Go programming is suitable for embedded systems due to its parallelism, low memory footprint, convenient tools, and built-in hardware support. Practical example: Blinking LED lights on Raspberry Pi using Go, code includes pin configuration, looping and GPIO operations.

Embedded Go Programming

Go is a popular general-purpose programming language that is growing in popularity for embedded system programming. The following is a brief introduction to programming Go for embedded systems, including a practical example.

What is an embedded system?

Embedded systems are computer systems specifically designed to perform specific tasks, usually as a component of a larger system. They typically use a microcontroller or microprocessor as their computing engine.

Why Go is suitable for embedded programming

• Parallelism: Go’s concurrency model makes it well-suited for processing embedded systems Common concurrency issues in .
• Low memory footprint: Go programs generally use less memory than programs written in other languages.
• Convenient Tools: Go comes with various built-in tools for cross-compiling, debugging, and analyzing code in embedded systems.
• Built-in hardware support: The standard library includes support for common embedded hardware such as GPIO, UART, and I²C.

Practical Case: Flashing LED

Let us demonstrate embedded Go programming through a simple practical case. We will use LED light blinking on the Raspberry Pi.

package main

import (
    "machine"
    "time"
)

func main() {
    led := machine.Pin(13)
    led.Configure(machine.PinConfig{Mode: machine.PinOutput})

    for {
        led.Set(true)
        time.Sleep(time.Millisecond * 500)

        led.Set(false)
        time.Sleep(time.Millisecond * 500)
    }
}

Code description:

• We start by importing the necessary libraries.
• We use machine.Pin(13) to configure the 13th pin of the Raspberry Pi as the output pin.
• We use an infinite loop to turn the LED light on and off every 500 milliseconds.
