I2C is a two wire, clock synchronized protocol with a bi directional data line and a uni directional clock line. Its simplicity lies in its use of only two lines for communication and its complexity ...

This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

Check out LIN and I2C for low speed networking needs. They are often better alternatives than SPI or CAN for many applications. The serial peripheral interface (SPI) and universal asynchronous ...

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 ...
