![]() 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. ![]() So we will use the Arduino Wire Library which has to be include in the sketch. Multiple objects (for multiple software I2C buses) and clock-stretching by slave devices are supported. In this tutorial we will learn how the I2C communication protocol works. 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. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. The MKR Vidor 4000 is the first Arduino board equipped with an FPGA processor. It utilises the pinMode(), digitalWrite() and digitalRead() functions. To make it easier, Arduino has also released two libraries that you can use to play and analyze audio and connect other digital audio devices. ![]() SoftWire is a software I2C implementation for Arduino and other Wiring-type environments.
