Selecting a Serial Bus

There is a good article about selecting the right microcontroller serial bus in this months Electronic Products magazine. Many people are like me, they use what they know. This article has a good explanation of the differences so that we can make a better informed decision for the next product. “At the heart of most of today’s advanced electronic products is a microcontroller that communicates with one or more peripheral
