Which microcontroller supports I2C protocol?

The following figure shows interfacing I2C-EEPROM with 8051 microcontroller. Here, I2C is a master- slave protocol, that includes the data along with clock pulse.

What devices use I2C?

I2C Sensor Examples

• Differential Pressure Sensor (SDP611)
• IR Temperature Sensor (MLX90614)
• SHT3x Temperature and Humidity Sensor.
• Adafruit 10-DOF IMU Breakout.
• Accelerometer & Compass Module (LSM303)
• Compass (LSM303)
• Accelerometer (LSM303)
• Accelerometer (ADXL345)

Is I2C a device?

The I2C, or inter-integrated circuit, protocol is one example of a serial protocol for devices to communicate with one another. The I2C protocol only uses 2 wires to send and receive data. One line is a clock, called SCL, which pulses high and low to drive the sending and receiving of bits.

How does I2C work in microcontroller?

I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line). Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. The clock signal is always controlled by the master.

What is I2C protocol in Arduino?

The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.

What is I2C in IoT?

I2c namespace to allow apps to communicate with Inter-Integrated Circuit devices (commmonly abbreviated IIC or I2C) on a Windows IoT (Internet of Things) device. I2C is a two-wire low-speed bus used to interface devices such as sensors, EEPROMs, and touch controllers.

Does Arduino Uno has I2C?

The Arduino Uno board has only one I2C module, but it provides these SDA and SCL line at two different locations. Note: While communicating with devices using I2C communication protocol, pull-up resistors should be used.
