Come on, let’s see how an idea in your brain can be transformed to a working embedded systems. What are the key steps you would be following each type you design a system. The key characteristic of embedded system is that it inherits much of its functionality from a well designed program. Everything the embedded system is able to do is through a program which is running inside the microcontroller. This program is a special type of "software" called a firmware. Because it is "firm" in nature because the embedded system once programed and deployed to the end user will be running the same program through out its life time. For example a TV remote control runs the same program which encodes key press data into serial bit stream and sends through an IR transmitter. Same is the case with a MCU inside a pen drive, digital watch and calculators. In contrast a "software" like MS Word or Firefox is not that much "firmly" tied to your PC or Phone. Your PC can run several other software in addition to these and also they can be replaced by their alternatives. So development of embedded software (i.e. firmware) and its installation on microcontroller should be clear to the user. Step I – Development of Program A program is a step by […]
