Formerly, automobile manufacturers used to connect various electronic devices in automobiles using a number of wires through point-to-point connections. This resulted in huge wire connections which were very expensive and bulky. Later, this complicated wiring system got replaced by dedicated wiring that enhanced communication speed between devices and provided high integrity, and was named as controller area network. The CAN was first developed by Bosch in the year 1985 for in-vehicle … [Read more...]
What is Serial Peripheral Interface : Working and Its Applications
As we know that communication between humans happens in multiple languages, in a similar way communication between electronic devices happens. But both the communication devices should speak the same language. The languages that the devices speak are termed communication protocols. There exist a few communication protocols such as UART communication, I2C protocol, and SPI (Serial Peripheral Interface) protocols. Today, this article let us understand the SPI protocol definition, its block … [Read more...]
What is I2C Protocol : Architecture, Timing Diagram & Its Applications
In the process of establishing a connection between multiple devices in a microcontroller, the data and address line of every single device would take up important pins in the microcontroller which leads to more traces on the PCB board. And also it requires more components which further results in cost enhancement of the system and they are even easily subjective to noise and intrusion. So, to stay back from this complication Philips introduced IC buses which were also called I2C in the year the … [Read more...]
What is a Network Protocol : Types & Its Working
A protocol can be defined as a set of rules in a computer network used to process and format the data. For computers, these protocols work like a common language which may use very different hardware as well as software to allow them to converse with each other. The communication between two computers can be done only if they use IP (Internet Protocol). But if any one of the computers uses internet protocol then they will be incapable to converse. There are different types of protocols … [Read more...]
What is Modbus : Working & Its Function Codes
In 1979, a data communication protocol called Modbus was developed by Modicon (now Schneider Electric) and it is used along with its PLCs (programmable logic controllers). It is an industrial standard protocol and it is mainly used in process and factory automation. Now it is commonly referred to as a de facto communication protocol to connect various industrial electronic components. In the electric power industry, this is used to connect a supervisory computer with RTU (remote terminal unit) … [Read more...]
