In this tutorial, you’ll learn about ESP32 I2C communication protocol (in Arduino IDE). We’ll discuss how ESP32 I2C works, how to change I2C default pins (SDA, SCL), how to connect multiple I2C devices on the bus with proper addressing, and how to create an ESP32 I2C scanner to ...

Because the I2C protocol allows for each enabled device to have it's own unique address, and as both master and slave devices to take turns communicating over a single line, it is possible for your Arduino or Genuino board to communicate (in turn) with many devices, or other boards, whi...

One advantage of I2C over a communication standard such as SPI is that it has a built-in communication protocol that allows easy, error-free communication between devices. The Cypress PSoC 1 device offers several choices for implementing I2C in a design. These choices come in th...

The technical basis for this “tap to connect” process is provided in the NFC Connection Handover specification running atop the NFC Forum protocol stack. It defines a framework of messages and data containers that allow bootstrapping of alternative (i.e., other than NFC) carrier connections ...
In the master-Slave communication process of I2C, the SCL clock on the bus is always generated and controlled by the master, but if the slave cannot keep up with the speed of the master, the I2C protocol stipulates that the slave can pull down the SCL clock line. A transfer is suspended...
