Espressif Systems is a fabless semiconductor company renowned for delivering cost-effective wireless communication microcontrollers. Its innovative solutions are widely adopted in Internet of Things (IoT), consumer electronics, and embedded applications around the globe.

General

• Issues with boards (wrong / missing). All issues caused from boards will not be fixed from the maintainer(s). A PR needs to be provided against branch develop to solve.
• No support for the Arduino Nora Nano board, issues needs to be solved by the community

IDE Preparation

Prerequisites:

• VSCode: git is required for pioarduino to function properly.
• CLI: Python (v.3.10, v.3.11, 3.12, 3.13 or 3.14) is additionally needed

Installation

VSCode Extension

• Download and install Microsoft Visual Studio Code. pioarduino IDE is on top of it.
• Open the extension manager.
• Search for the pioarduino ide extension.
• Install pioarduino IDE extension.

CLI

curl -fsSL -o get-platformio.py https://raw.githubusercontent.com/pioarduino/pioarduino-core-installer/pioarduino/get-platformio.py
python3 get-platformio.py
source ~/.platformio/penv/bin/activate

Note: The pioarduino platform installer automatically fixes the virtual environment if a conflict with the system Python is detected.

Usage

VSCode

Setup new VSCode pioarduino project.

CLI

mkdir my-project && cd my-project
pio project init --board esp32dev

Features

Filesystem Support

pioarduino provides native support for multiple filesystem options, allowing you to choose the best solution for your project's needs:

• LittleFS (default) - Modern wear-leveling filesystem designed specifically for flash memory. Offers excellent reliability and performance for ESP32 projects.
• SPIFFS - Simple legacy filesystem. While still functional, LittleFS is recommended for new projects due to better wear-leveling and reliability.
• FatFS - Industry-standard FAT filesystem with broad compatibility across platforms and operating systems.

Quick Start:

[env:myenv]
board_build.filesystem = fatfs

Available Commands:

pio run -t buildfs        # Build FatFS image
pio run -t uploadfs       # Upload FatFS image
pio run -t download_fatfs # Download and extract FatFS from device

See the arduino-fatfs example for a complete working example.
