Communication Protocols in Embedded Systems

Communication protocols are central to how we understand and develop embedded systems and devices. A communication protocol is a defined system that allows two or more entities in a communications system to talk to each other. Communication protocols define the rules of communication, syn...

The design and development process for embedded systems is uniquely challenging. This is, at least in part, due to the complexity of systems that involve both hardware and software operating within tight resource and timing constraints. In truth, the need to operate within these constraints while reliably delivering functionality o...

The Internet of Things (IoT) has become one of the largest areas of technological advancement. In the past decade, internet connectivity has been extended from mainframes to mobile smart phones. Now, with the IoT, internet connectivity is present in many types of devices that we interact with on a daily basis, including home appliance...

System Management Bus Protocol, also known as SMBus, is a two-wire protocol that supports basic communication functions, often within computer motherboards. Defined by Intel and Duracell in 1994, the standard has grown steadily in usage due to its functional benefits and compatibility with the existing I2C two-wire protocol. Today, ...

If you're an embedded systems engineer, you may want to build a product that either takes input from a human operator or delivers outputs to an operator through a human-readable interface. When such functions are to be implemented, it is common for engineers to use a special type of communication protocol known as the Human Interface ...

The I2C serial communication protocol was first invented by the Philips Semiconductor company, now known as NXP Semiconductors, in 1982. Now approaching its 40th anniversary, the protocol offers an effective means of short-distance intra-board communication that is ideal for embedded systems and micro-computing applications where the pr...
