The live GPIO pin monitoring library sets up the ESP32 to stream information about what all of the pins are doing in real time to a webserver, which displays the information as a helpful graphic.

This is demonstrated once again, this time on the ESP32 by [aquaticus] with a library ... The composite signal itself is generated on GPIO 25, with the selection from a wide number of PAL and ...

General-purpose Input/Output (GPIO) is an interface available on most ASICs to provide ease of access to the device's internal properties. There can be several GPIO pins that depend on the application ...

We made something similar but using the RP2350A board, the Raspberry Pi Pico 2, and published a guide on how to get Wi-Fi on the Pico 2 using an ESP32 ... with more GPIO pins than the RP2350A ...
