![]() ![]() ![]() This functionality, however, takes advantage of a timing slowdown in the current Wire() library. Note: Any I2C‑MaxSonar sensors shipped after 10/29/14 were updated to support faster speeds and work with the current Arduino Wire() library. We have also provided some of the educational information related to this specific I2C implementation. Never fear! We have worked to provide a clear and easy to follow path to get an I2C‑MaxSonar up and running on your Arduino. The short answer is "Yes." The more technical answer is – be prepared to install a new library and learn a bit about digital electronics. While (Wire.A number of customers have asked if the Arduino supports talking to the I2C‑MaxSonar sensors over an I2C interface. Wire.requestFrom(0x08, 14) // request 14 bytes from slave device 0x08 Wire.endTransmission() // End transmission Wire.write(GET_NAME) // send data to the slave Wire.beginTransmission(0x08) // Start channel with slave 0x08 Serial.begin(9600) // start serial for output Wire.begin() // join i2c bus (address optional for master) * i2c network: send parameter to client and receive response Like UART communication, I2C only uses two wires to transmit data between devices: Some variants also support 10 Kbps and 1 Mbps. I2C supports 100 kbps, 400 kbps, and 3.4 Mbps. It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. It is a synchronous, multi-master, multi-slave, packet switched, single-ended, serial communication bus. It was invented in 1982 by Philips Semiconductors. I 2C ( Inter-Integrated Circuit, eye-squared-C) is alternatively known as I2C or IIC. ![]()
