ESP32 NDJSON HMI – UART-Controlled Firmware
A Nextion-like HMI, but without the pain. This ESP32 firmware uses plain JSON over UART to create and control the UI dynamically. No editor, no compiling screens — just send commands and get events back. Simple, transparent, and made for real embedded projects.
