Access the Raspberry Pi's GPIO Pig Pen

For as long as the Raspberry Pi has been around, wiringPi has served as a library for accessing the GPIO. With the related gpio tool, programmers could quickly manage the GPIO at the command line. Many Raspberry Pi projects build on this library.

Not least because of frustration about what were in part rude email communications from some users, developer Gordon Henderson decided to discontinue his one-man wiringPi project in August 2019 after releasing his last version. He explained in great detail on his website why he had stopped developing the library. The post, which has since been deleted, is still available on the Wayback Machine internet archive [1]. For more information, see the box “The Two Sides of Open Source.”

The Two Sides of Open Source

The open source community makes many software projects available to the general public. Open source thrives on enthusiasts who develop projects in their spare time. All too often, however, it happens that these developers do not get any recognition for their work. On the contrary, many people expect developers to provide the kind of professional support you would want from a corporate vendor, and people are even insulted if bugs are not fixed immediately. As a result, projects repeatedly disappear because developers no longer want to work under these conditions.
