The past 10 years or so has seen a lot of changes in my life dominated by physical and mental health issues, businesses coming and going, but also a little fun with retro-computing, arduino, and the Raspberry Pi, and the wiringPi GPIO … WiringPiはRaspberry PiのGPIOを制御するためのC言語ライブラリですが、他の言語、例えばPythonやPHPなどからもこのライブラリにアクセスできるようになっています(具体的にはラッパが用意されています)。 ... pi@raspberrypi ~ $ sudo apt-get install libi2c-dev. These are temporary cookes which should only be held in the memory of your browser and be deleted when you shutdown the browser or reboot your computer. pinMode (6, 1) # Set pin 6 to 1 ( OUTPUT ) wiringpi. (starting from PIN_OFFSET >= 64) as if they were normal pins on the Pi.This example was tested on a quick2wire board with one digital IO Install WiringPi on Linux (general) Raspbian is the officially supported OS for Raspberry Pi, but there are many other Linux OSes adapted for the Pi, for example Ubuntu Mate . 2.46.0 (Or none which disables it)This uses the BCM_GPIO pin numbering scheme and performs the same operation as above.This uses the physical P1 pin numbering scheme and performs the same operation as above.The GPIO lines have internal pull up or pull-down resistors which can be controlled via software when a pin is in input mode. Make sure it’s always at the top of your program, and make sure you only call it once!If you’ve already programmed on Arduino, you should feel very familiar with those 2 lines. Always prefer using them in your code, instead of just 0 and 1.This code is pretty straightforward. Installing the WiringOP library Log on to the user account where you want to install the library, go to the / home directory for example, and then start recovering sources from GitHub. These are temporary cookes which should only be held in the memory of your browser and be deleted when you shutdown the browser or reboot your computer. digitalWrite (6, 1) # Write 1 ( … wiringPiSetupSys # For /sys/class/gpio with GPIO pin numbering # OR wiringpi. WiringPi is extendable and modules are provided to extend wiringPi to use analog interface devices on the Gertboard, and to use the popular MCP23x17/MCP23x08 (I2C 7 SPI) GPIO expansion chips, as well as module that will allow blocks of up to 4 74×595 shift registers to be daisy-chained together for an additional 32-bits worth of output as a single unit. Some features may not work without JavaScript. This will be easier for you to be in sync with other developers, and if you switch to another library (for example RPi.GPIO with Python), you will be able to use the same pin numbers.In this example we’ll manage a LED and a push button using the Raspberry Pi GPIO header.The goal of the program is to use WiringPi to read the data from the push button (digital input) and power the LED on (digital output) when the button is pressed.We’ll use the core functions from the WiringPi library, and if you’re familiar with Arduino, you’ll see that those functions are almost the same!The pin numbers inside WiringPi code follow the BCM pin numbering, so, use the “BCM” column from the previous table in order to find the correct number to use.The LED is connected to BCM pin 17, which is also WiringPi pin 0, and physical pin number 11.The push button is connected to BCM pin 18, which is also WiringPi pin 1, and physical pin number 12.Let’s keep things simple and use only the BCM pin number convention (GPIO 17 and GPIO 18) for the rest of this tutorial.In this hardware setup I’ve used a 220Ohm resistor for the LED and a 10kOhm pull-down resistor for the push button.
