When developing embedded systems, various types of components are used to create a functioning system, including a combination of a computer processor, memory, and input/output peripheral devices. Each embedded system is different and ranges in complexity depending on its desired objective. One of the decisions engineers must make w...

The Data Center Software is Total Phase’s free bus monitoring software that is used in conjunction with the line of Beagle Protocol Analyzers, Komodo CAN Duo Interface, USB Power Delivery Analyzer, and Promira Serial Platform with the eSPI Analysis Application. This software provides an interface that is used to capture, monito...

PMBus, or Power Management Bus, is two-wire interface that defines the management of power subsystems. This bus is an extension of the SMBus protocol, so PMBus and SMBus hold many similarities. In this article, we’ll provide a high-level overview of the background of PMBus, how PMBus operates, where it’s used, and ways to debug ...

SMBus, PMBus, and I2C protocols are communication protocols used for inter-device communication in embedded systems. While these protocols are similar in many ways, including their physical layer, there are also multiple differences in how they operate and where they are used.

Because the SMBus standard is based on th...

SMBus, or System Management Bus, is two-wire interface often used for low-speed system management communication between devices on a motherboard. This bus was developed using the foundations of the I2C protocol, so SMBus and I2C hold many similarities and can even inter-operate on the same bus. In this article, we’ll ...

Communication protocols are some of the essential building blocks of an embedded system. They are what governs how data is sent over the bus, including whether data is sent serially, parallelly, asynchronously, or through a master/slave paradigm.

There are multiple forms of communication that can be used in an embedde...
