They can therefore be used on klipper simply by referring them with the name `gpio0..n`. However, there are cases in which the exposed pins belong to gpiochips other than the first. For example in the case of some OrangePi models or if a Port Expander is used. In these cases it is useful to use the commands to access the _Linux GPIO character device_ to verify the configuration. -To install the _Linux GPIO character device - binary_ on a debian based distro like octopi run: +To install the _Linux GPIO character device - binary_ on a debian based distro like OctoPi run: ``` sudo apt-get install gpiod ``` |
