The microcontroller must function as the master device, multiple masters are not supported. A timeout feature is included to prevent lockups by faulty or missing hardware. It is intended to be compatible with the RF Monolithics (Virtual Wire protocol, but this has not been tested.

Multiple objects (for multiple software I2C buses) and clock-stretching by slave devices are supported. Alternatively it is possible to pass references to functions which read and control the SDA and SCL lines, thereby allowing direct port manipulation to be used if preferred. Arduino/libraries/Wire directory on the machine you write your code on. It utilises the pinMode(), digitalWrite() and digitalRead(). The Wire Library is a series of files in plain text that exist in the. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. INSTALL: Install it from Arduino IDE Library Manager. More than one software I2C bus can be created. It utilises the pinMode(), digitalWrite() and digitalRead() functions. This is a library that creates a software I2C bus on any two pins of an Arduino Uno, Leonardo, Pro Mini, Mega, and alike. SoftWire is a software I2C implementation for Arduino and other Wiring-type environments.
