# Getting Started

Linuxduino is a port of the Arduino Programing language for embedded systems running Linux (e.g., Raspberry PI, DragonBoard 410c, even your own Linux Computer). Linuxduino is a C++ library and has been ported to JavaScript using WebAssembly.

# Install

# JavaScript

npm install linuxduino

# C++

todo

# Usage

# Blink an LED in Javascript

const linuxduino = require('linuxduino');

// Test digitalWrite
(async() => {
  // Wait for wasm file
  await linuxduino.ready;

  var ledPin = 4; // Embedded board GPIO Number
  linuxduino.pinMode(ledPin, linuxduino.OUTPUT);
  while(1) {
    console.log("LED ON");
    linuxduino.digitalWrite(ledPin, linuxduino.HIGH);
    linuxduino.delay(1000); // Delay 1 sec
    console.log("LED OFF");
    linuxduino.digitalWrite(ledPin, linuxduino.LOW);
    linuxduino.delay(1000); // Delay 1 sec
  }
  return 0;
})();

Run it

sudo node digitalWrite.js

# Blink an LED in C++

#include "Linuxduino.h"

// Test digitalWrite
int main(void) {
    int ledPin = 4; // Embedded board GPIO Number
    pinMode(ledPin, OUTPUT);
    while(1) {
        printf("LED ON\n");
        digitalWrite(ledPin, HIGH);
        delay(1000); // Delay 1 sec
        printf("LED OFF\n");
        digitalWrite(ledPin, LOW);
        delay(1000); // Delay 1 sec
    }
    return 0;
}

Run it

g++ digitalWrite.cpp -o digitalWrite -llxduino
sudo ./digitalWrite

Check the Reference to see the full list of implemented functions and examples.

# Arduino style compatibility for C++

C++ programs can also use the Arduino programming style by including the Arduino.h instead of Linuxduino.h header and compiling them with -llxarduino instad of -llxduino. Example:

# Blink an LED in C++ using the Arduino programming style.

#include "Arduino.h"

// Test Arduino style digitalWrite

int ledPin = 4; // GPIO4

void setup () {
    pinMode(ledPin, OUTPUT);
}

void loop () {
    printf("LED ON\n");
    digitalWrite(ledPin, HIGH);
    delay(1000);
    printf("LED OFF\n");
    digitalWrite(ledPin, LOW);
    delay(1000);
}

Run it

g++ digitalWrite.cpp -o digitalWrite -llxarduino
sudo ./digitalWrite

Note that Wire.h and SPI.h should be included separately if Arduino.h is used.
