WiringPi is a PIN based GPIO access library written in C for the BCM2835, BCM2836 and BCM2837 SoC devices used in all Raspberry Pi. It’s released under the license and is usable from C, C++ and RTB (BASIC) as well as many other languages with suitable wrappers (See below) It’s designed to be familiar to people who have used the Arduino “ wiring” system 1 and is intended for use by experienced C/C++ programmers. It is not a newbie learning tool. WiringPi is developed directly on a Raspberry Pi running 32-bit Raspbian. I do not support any other platform, cross compiling or operating systems. First, I’ve searched, if there’s another post that describes where, how to find the Wire.h library in the Particle Build Library search box point me in the right direction. A catalogue of the 1789 Arduino Libraries. Arduino Library List. This site is generated automatically from the 1789 libraries registered in the Arduino Library Manager. It has been ported to other platforms, other operating systems and some are cross compiling, however this author does not maintain those systems. If you are trying to use wiringPi on a platform other than the Raspberry Pi with Raspbian then you must contact the person who did the port and not me. The original Model A and B version B1 was a $35 single board computer with a 26-pin General Purpose Input/Output (GPIO) connector and this carries a set of signals and buses. There are 8 general purpose digital I/O pins – these can be programmed as either digital outputs or inputs. Two of these pins (on 40-pin Pi’s, just one on 26-pin Pi’s) can be designated for hardware PWM output too. Additionally there is a 2-wire I2C interface and a 4-wire SPI interface (with a 2nd select line, making it 5 pins in total) and the serial UART with a further 2 pins. Over the years there have been some updates: • The original model B with the 26-pin GPIO connector. • The model B, Revision 1.1 Raspberry Pi has an additional 4 GPIO lines on a separate connector which you have to solder onto the board. ![]() • The model A which is essentially the same as the model B v1.1 but without the USB hub and ethernet connector. • The model A+ and B+ Raspberry Pi’s represents 2 years of research, development and testing and now features a single 40-pin GPIO connector with 28 usable GPIO pins and 4 USB sockets. (No USB or Ethernet on the A+) • The model B v2 features a quad-core Arm A7 processor with 1GB of RAM. • The model Zero is a souped-up (1GHz) cut down Pi A+. 40-pin GPIO connector and very little else. $5 price tag. • The model B v3 features a quad-core Arm A8 processor (64-bits) with the same RAM and GPIO as the model 2, however it also features on-board Wi-Fi and Bluetooth.

The I2C, SPI and UART interfaces can also be used as general purpose I/O pins when not being used in their bus modes, giving a grand total of 8 + 2 + 5 + 2 = 17 I/O pins on the P1 connector (plus 4 more on the P5 connector on a Revision 2 Pi) and 28 I/O pins on the B+ and version 2 and 3 boards (Although 2 are reserved for the HAT I2C interface, but can be used as normal GPIOs if not using a HAT board) 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. 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. (You can have several blocks of 4 74x595s if needed) One of the extension modules allows you to use an ATmega (e.g. Avast driver updater key 2018. Arduino, or the Gertboard) as more GPIO expansion too – via the Pi’s serial port. Additionally, you can easily write your own extension modules to integrate your own peripheral devices with wiringPi as required. Please Rate 5 ★Stars & Write a Review if You Love This Game.
