The I nter-Integrated Circuits (I2C) protocol has been around for three decades but is still widely used in embedded systems today. These applications are using the I2C protocol. Now consider when you move from a dark room to a brightly lit area and how you might need to boost the brightness on your phone screen in order to read a text. Think about switching your tablet screen to night reader mode and the way the colors invert to make reading easier on your eyes. Total Phase offers two types of CAN products: the Komodo Solo CAN Interface and the Komodo Duo CAN Interface. It is message-based and now used in various manufactured applications such as cars, trucks, and buses - both gasoline powered and electric - as well as aviation equipment, automated machinery, elevators, and medical equipment. The microcontrollers and devices within the network could now communicate with each other without a host computer. What CAN SupportsĮngineers producing new vehicles could now manage the electronic subsystem in cars with a single cable. To keep expenses low and simplify the in-vehicle wiring and machinery, he implemented CAN. All of these advanced features meant more complex designs and heavier-duty mechanical parts that were more expensive than ever before. Robert Bosch, the developer of the CAN protocol, recognized the need to make intelligent vehicles more affordable and practical.Ĭars in the late 1970s were just beginning to see changes such as anti-lock braking systems, air conditioning, central door locks, airbags, gear control, and management systems. The Controller Area Network (CAN) protocol was created with the intent to minimize and downsize communication processes in automobiles.

In this piece, we will dive into five serial communication protocols you should know in order to stay up to date on how embedded systems are communicating second by second, day by day. In order to keep your ever-modernizing world connected at the speed you’re accustomed to, serial communication protocols have been created to process digital information securely, efficiently and smartly. When receiving data, the microcontroller on the other end can convert the information back to a parallel form. When a microcontroller in an embedded system contains a particular data set, it is stored in parallel form but converts to serial data when it is transferred to the output buffer. Why is serial communication necessary? To function properly and keep your world connected, embedded systems need to be highly functioning and continuously interpreting, cycling, updating, and sharing information.

The end result is serial communication generally offers superior performance and speed. When there are fewer conductors - and there are fewer conductors present when serial communication is used - there are fewer inconsistent signals. Transmission speeds and signal integrity are also becoming stronger making serial communication a better option today even when it comes to communication across shorter distances.Īlthough it would seem parallel communication should be faster than serial communication, which would make it seem like the optimal choice, the reality is that serial communication requires fewer cables to transmit the data and there is less crosstalk, undesired signal glitches happening from one channel to the next. While parallel communication might seem simpler, serial communication is more economical in terms of long-distance communication, or cable channels that span long distances. In comparison, parallel communication sends several bits of information as a unit all at the same time. Usually, this transfer of information happens between two or more components of embedded systems. Using JavaScript and a very simple script im changing the background of a webpage from white to black on 100 milliseconds intervals and reading the result on my brightness sensor, as expected the browser is not very precise on timing, some times it does 100ms sometimes less and sometimes more with a huge deviation at times.Serial communication in the world of telecommunications is the sequential transfer of data one bit at a time over a communication channel or communication bus.

This is an embedded solution using C++, im reading the changes of brightness from a cellphone screen, from very bright (white) to dark (black).
