Elevate your Arduino projects with PlatformIO

If you use the Arduino IDE and want something better, start using PlatformIO. It is a comprehensive tool for many boards across many platforms.

Install

pip install platformio

Start a new project

mkdir foopio
cd foopio
pio project init

Open the project in your editor and add this to platformio.ini:

[platformio]
default_envs = esp32dev

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino

Create the firmware entry file:

touch src/main.cpp

Blink example

#include <Arduino.h>

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

void loop() {
    digitalWrite(LED_BUILTIN, HIGH);
    delay(1000);
    digitalWrite(LED_BUILTIN, LOW);
    delay(1000);
}

Connect your device and upload:

pio run -t upload
