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.

The GPIO pins on the Raspi are arranged in a 2×13 header. Until Sparkfun manages to manufacture a decent Raspi protoboard, the easiest way to break these pins out is with an old IDE ribbon cable.

Also, set the virtual GPIO interface to the GPIO agent using hierarchical reference so that the pin-level activities to be performed by the agent can get those references. Extend the GPIO controller ...

General purpose input-output (GPIO) pins are the simplest peripherals. The link to an object under control (OUC) may become inadvertently unreliable due to many reasons: a loss of contact, short ...

Giada has taken the importance of GPIO to heart, offering embedded PCs like the DF613-I and AF208, both of which come with ...

40 Pin Raspberry Pi PCB GPIO Quick Connect Clip. 2:14 pm November 7, 2017 By Julian Horsey. Raspberry Pi enthusiasts looking for a quick way to add GPIO pins for prototyping that can be then ...

That comes via the standard 40-pin GPIO header on the full-sized boards. But in order to shrink down the size, the Raspberry Pi Zero had to forego the header while still retaining the GPIO contacts.
