TL;DR
The article discusses a project by Tony Weston that achieves 20 frames per second (FPS) on an electronic paper display using an ESP32 microcontroller, without the need for additional processing power. This is noteworthy because e-paper displays typically struggle with refresh rates, often limited to single-digit FPS in older models and around 10-20 FPS in mid-range devices, which usually require more advanced hardware.
