With the emergence of various digital communication protocols and interfaces (UART, I2C, SPI, USB, etc), embedded system designers commonly face challenges with incompatibility between interfaces, on general purpose ICs, while integrating them into one design. These issues range from interfacing with legacy systems, managing communications among various bus interfaces, and attaching multiple systems with different interfaces to a main processor. This article starts with a brief introduction of the digital communication interfaces and protocols that have dominated embedded system design, and then discusses three common interface incompatibility situations along with the corresponding approaches for handling them. The conclusion will provide suggestions to embedded system engineers on how to avoid or tackle interface incompatibility issues. To read more, click the download link below or visit EN-Genius.
