Embedded Systems

Embedded Software is a key element in every embedded project that is used to run the micro-controller to perform the desired operations. In our daily life, we frequently use many electronic devices such as washing machines, refrigerators, mobile phones, security system, digital camera so on which will be controlled using embedded C program. If you press a button to take a photo with your digital camera, then micro-controller will perform the functions essential to capture the image and store it. This article presents basics of embedded systems micro-controller consists of many ports to construct the embedded C programming tutorial An embedded system is the one that has computer-hardware with software integrated in it as the most significant component. It is a dedicated computer-based system, may be independent or part of a large system with the following components:

1. Hardware: It includes processor, timers, I/O devices, ports, memories, ports, etc.

2. Application software: To perform multiple tasks at the same time.

3. Real Time Operating System (RTOS): It supervises the application software and provides a mechanism to let the processor run a process as per scheduling and perform the context-switch between different processes.
