gpio-line-names may help to make work with GPIOs from user space easier. Following examples are provided with libgpiod https://github.com/brgl/libgpiod : |# Toggle a GPIO by name, then wait for the user to press ENTER. |$ gpioset --mode=wait `gpiofind "USR-LED-2"`=1 |# Pause execution until a single event of any type occurs. Don't print |# anything. Find the line by name. |$ gpiomon --num-events=1 --silent `gpiofind "USR-IN"` Used names was taken from RIoTboard schematics, version 1 (2013.12.07).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
