Watch ESP32’s GPIO status in real-time in a web browser

GPIOViewer is an innovative open-source Arduino library designed for real-time monitoring of GPIO pins on ESP32 boards via a web browser. It provides a dynamic and graphical representation of the board's GPIO pin status, enhancing troubleshooting and project development. Key features of the library: ➡️ Displays live status of digital, analog, and PWM signals on ESP32 GPIO pins. ➡️ Tracks actual hardware status, differentiating it from simulation-only tools like the Wokwi ESP32 simulator. ➡️ Utilizes ESPAsyncWebServer and AsyncTCP libraries, with the latter available through the Arduino IDE’s Library Manager. ➡️ Adds only about 50 KB to projects. ➡️ Recommended to use with strong Wi-Fi connections for lower latency and faster data sampling. ➡️ Supports a variety of ESP32 boards, including ESP32-VROOM-32, Olimex ESP32-EVB, and more. This real-time GPIO monitoring capability is not only a boon for debugging but also enhances the overall user experience in developing and testing ESP32-based projects.
