Prerequisites

Before you begin coding for the glyphC3, you must configure your development environment and install the necessary dependencies.

1. Environment Setup

Follow the complete guide below to set up the Arduino IDE and configure the ESP32-C3 board package:

• glyphC3 Arduino IDE Setup Guide

2. Library Installation

Open the Library Manager in the Arduino IDE (Sketch > Include Library > Manage Libraries) and install the following:

• ArduinoJson (by Benoit Blanchon)
• Adafruit SSD1306 (by Adafruit)
• Adafruit GFX Library (by Adafruit)

[!TIP] Libraries such as WiFi.h, HTTPClient.h, SPI.h, SD.h, and Wire.h are part of the ESP32 core and are installed automatically when you follow the setup guide above.
