This article shows how to build a simple weather station using an ESP32 and a 4.2″ SSD1683 eInk display, powered by the GxEPD2 library and the OpenWeatherMap API. A low-power project that displays real-time temperature, humidity, wind, and pressure.
Continuing our previous tutorial on configuring the ESP32 SSD1683 display and wiring, this article dives into text and shape rendering, demonstrating font scaling with setTextSize(), custom GFX fonts via setFont(), and drawing lines, rectangles, circles and rounded shapes. We’ll also cover converting images to 1-bit byte arrays with the online generator and displaying them on the E-Ink screen.
