I2C at Raspberry Pi GPIO Pinout The Raspberry Pi's I2C pins are an extremely useful way to talk to many different types of external peripheral; from the MCP23017 digital IO expander, to a connected ATmega. The I2C pins include a fixed 1.8 kohms pull up resistor to 3.3v. This means they are not suitable for use as general purpose IO where a pull up is not required. wiringPi: Access GPIO pins on Raspberry Pi via wiringPi ... A pin can be identified by its physical pin number, by its Broadcom GPIO number (this is the one most commonly used in the Raspberry Pi community), or by its wiringPi pin number. The Pin type has three constructors (Wpi, Gpio, and Phys), allowing you to call a pin by any of its three names. These names are synonymous and interchangeable.
