The GPIO utility | Wiring Pi The GPIO lines have internal pull up or pull down resistors which can be controlled via software when a pin is in input mode. There is no way to read the status of these resistors. These set the resistors to pull up, pull down and none respectively on wiringPi pin 0. Core Functions | Wiring Pi If you need to change the pin mode, then you can do it with the gpio program in a script before you start your program. void pullUpDnControl (int pin, int pud) ; This sets the pull up or pull down resistor mode on the given pin, which should be set as an input. Unlike the Arduino, the BCM2835 has both pull up an down internal resistors. The GPIO utility | Gordons Projects The GPIO lines have internal pull up or pull down resistors which can be controlled via software when a pin is in input mode. gpio mode 0 up gpio mode 0 down gpio mode 0 tri These set the resistors to pull up, pull down and none respectively on wiringPi pin 0. wiringPi: Access GPIO pins on Raspberry Pi via wiringPi ... Unlike some other solutions for using the Raspberry Pi's GPIO pins, wiringPi provides access to more advanced features, such as enabling the internal pull up or pull down resistors. This is a Haskell binding to the wiringPi library, which allows you to interface with the GPIO pins on the Raspberry Pi. Using PullUp and PullDown Resistors on the Raspberry Pi RPi.GPIO basics 6 – Using inputs and outputs together with RPi.GPIO – pull ups and pull downs Pull up and Pull down Resistor Usage on Input or Output MCU Pins A three parter by Alex at RasPi.TV, titled "How to use interrupts with Python on the Raspberry Pi and RPi.GPIO". I2C: MCP23016 | Wiring Pi The gpio command supports the i2cdetect command and automatically caters for board revision. Simply type: gpio i2cd; The wiringPi MCP23016 driver knows which revision Pi you have, so you know need to take any special precautions – your code will work on either a Revision 1 or 2 Pi. The MCP23016 does not have any internal pull up down resistors. WiringPi at Raspberry Pi GPIO Pinout WiringPi. WiringPi is an attempt to bring Arduino wiring like simplicity to the Raspberry Pi. The goal is to have a single common platform and set of functions for accessing the Raspberry Pi GPIO across multiple languages. 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 ...
