Editor's Note: Embedded Systems Architecture, 2nd Edition, is a practical and technical guide to understanding the components that make up an embedded system’s architecture. Offering detailed ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

PCA9564 evaluation board description, features and operation modes are discussed. Source code in C language, containing communication routines between an 80C51-core microcontroller and the PCA9564 is ...

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 ...

The first parallel-to-serial I2C interface lets designers add I2C interfaces to any digital system. The PCA9564 controller provides a 400-kHz I2C serial bus and operates from 2.5 to 3.3 V. The chip is ...
