The GPIO utility | Wiring Pi The GPIO utility. WiringPi comes with a separate program to help manage the on board GPIO interface as well as additional modules such as the PiFace and other devices like the Gertboard as well as generic GPIO expander type devices. This program, called gpio, can also be used in scripts to manipulate the GPIO pins – set outputs and read inputs. WiringPi WiringPi includes a command line utility gpio which can be used to program and setup the GPIO pins. You can use this to read and write the pins and even use it to control them from shell scripts. You can use this to read and write the pins and even use it to control them from shell scripts. How to use WiringPi Library on Raspberry Pi | Raspberry Pi WiringPi is a library written in C used to access GPIO pins on Raspberry for BCM2835 (Broadcom Processor) SoC (System on Chip). There are various libraries are available to access GPIO in C like bcm 2835, sysfs, pigpio, etc. How to Control Hardware With the Raspberry Pi Using WiringPi pi@pi ~ src $ cd . wiringPi. pi@pi ~ src wiringPi $ . build. The WiringPi library offers easy access to the GPIO pins on the Raspberry Pi and provides both the command line tool gpio and an API for hardware interaction for your programs. It also includes some support for interacting with chips which are connected to the Raspberry Pi. Raspberry Pi web server Controlling GPIO with wiringPi The wiringPi libraries are a set of functions written in C that make it easy to control the Raspberry Pi's GPIO pins. You can use the functions in this library to control GPIO pins in your own programs. You can also use wiringPi on the command line. This is very useful for debugging problems with circuits connected to GPIO pins. The GPIO utility | Gordons Projects The gpio command is designed to be installed as a setuid program and called by a normal user without using the sudo command (or logging in as root). In addition to using the gpio utility to control the GPIO pins, you can: WiringPi orangepi.org What is the WiringPi Wiring Pi is a GPIO library written by Drogon. It is originally for the Raspberry Pi, but Orangepi has modified and adapted it to make it work on the Orange Pi mini Pi, we call it WiringOP.

WiringPi2 for Python is an excellent GPIO handling system written by Gordon ‘Drogon’ Henderson and packaged for Python by Phil ‘Gadgetoid’ Howard. It uses Arduino like scripting language. For simple GPIO work, I use RPi.GPIO because that’s what I first got started with. But, aside from hardware PWM,... 1: A single LED | Gordons Projects You can see that wiringPi pin 0 is GPIO 17. wiringPi pin 1 is GPIO 18, wiringPi pin 2 is GPIO 21 an so on. To use the GPIO pin numbering then you need to pass the g flag to the gpio program: gpio g write 17 1 gpio g write 17 0. This should turn the LED on then off again. And on to part 2 where we’ll add in 2 more LEDs.
