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 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. 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. Raspberry Pi web server Controlling GPIO with wiringPi You can also use wiringPi on the command line. This is very useful for debugging problems with circuits connected to GPIO pins. It's also useful for controlling GPIO with Bash scripts. The GPIO utility | Gordons Projects The gpio command reads the pin modes – so have a look at the source code of the gpio command to see how it’s doing that… Essentically there are un documented functions inside wiringPi to return the data needed. My take on the modes is that EVERY program should explicitly set the pins to the mode it needs. Raspberry gPIo learn.sparkfun pi@raspberrypi ~ code c_example $ gcc o blinker blinker.c l wiringPi. That command will create an executable file – “blinker”. The “ l wiringPi” part is important, it loads the wiringPi library. A successful compilation won’t produce any messages; if you got any errors, try to use the messages to track them down. I2C Library | Wiring Pi WiringPi includes a library which can make it easier to use the Raspberry Pi’s on board I2C interface. Before you can use the I2C interface, you may need to use the gpio utility to load the I2C drivers into the kernel: gpio load i2c. If you need a baud rate other than the default 100Kbps, then you can supply this on the command line: gpio load i2c 1000 Blink | Wiring Pi If you have the following saved in a file called blink.c: The LED is any generic LED you may have – typically 5mm diameter and the resistor is 330ω. You can find blink.c and others – blink8.c and blink12.c in the examples directory of the wiringPi distribution. 42 of the Most Useful Raspberry Pi mands After entering sudo su, you’ll see the root@raspberrypi: home pi# command prompt, and all subsequent commands will have super user privileges. Most of the commands below have a lot of other useful options that I don’t mention. To see a list of all the other available options for a command, enter the command, followed by – – help. WiringPi Orange Pi 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. Reference | Wiring Pi #include You may also need to add I usr local include L usr local lib lwiringPi. to the compile line of your program depending on the environment you are using. The important one is lwiringPi. You may also need additional #include lines, depending on the modules you are using. Reference API Pages. WiringPi Setup functions; Core wiringPi functions
