I2C is a wonderful interface. With four wires and only two GPIOs, you can connect a whole lot of sensors and devices – in parallel, at that! You will see I2C used basically everywhere, in every phone, ...

The AM2315 is a humidity and temperature sensor similar to the DHT12 with an I2C interface. Warning: this sensor is not compatible with the AM2315C. Although in theory this I2C interface can enable ...

You need to know the controller and the size of your display (Note: "Controllerless" displays are not supported by U8g2). In this example, we will use a ST7920 128x64 display. It has a ST7920 ...

In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has ...

Comparing I2C (Inter Integrated Circuits) in STM32F103C8 Blue Pill board with Arduino Uno, then we will see that Arduino has ATMEGA328 microcontroller in it, and STM32F103C8 has ARM Cortex- M3 in it.

I should really like I2C more than I do. In principle, it’s a brilliant protocol, and in comparison to asynchronous serial and SPI, it’s very well defined and clearly standardized. On paper, up to 127 ...
