📦 Requirements

1. Node.js 18+ — https://nodejs.org
2. Arduino CLI installed and in your PATH — https://arduino.github.io/arduino-cli/latest/installation/

Verify:

arduino-cli version

Install ESP32 core

arduino-cli core update-index --additional-urls https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
arduino-cli core install esp32:esp32 --additional-urls https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Install Raspberry Pi Pico (RP2040) core

arduino-cli core update-index --additional-urls https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
arduino-cli core install rp2040:rp2040 --additional-urls https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Install Arduino AVR core

arduino-cli core install arduino:avr

🚀 Run

npm install
npm start

Open http://localhost:3000

🧠 Using the Library Manager

1. Click the Libraries panel on the right.
2. Type a query (e.g. DHT) and press Search.
3. Click Install on any result.
4. The Installed list shows currently installed libraries with an Uninstall button.
5. When compiling, if the CLI reports a missing header, Code2MC will prompt you to auto-install the matching library.
