Raspberry Pi Foundation builds a bridge between PCs and GPIO pins
by from Techreport on (#39W6R)
The Raspberry Pi and its ilk generally lack the computing horsepower of a modern desktop or laptop computer, but one area where they excel is in physical computing, or interacting with a wide range of devices that control things in the real world. Typical PCs lack general-purpose input-output (GPIO) interfaces, and when they exist, the documentation is typically very poor.
To make the best of both worlds, the Raspberry Pi Foundation has now come up with a tool called the GPIO expander to shuttle data from a powerful computer into and out of the real world using a Raspberry Pi Zero's GPIO pins. This tool lets the Pi serve as ...
