Understand How Are Embedded Systems And Microcontrollers Different?

At the heart of most embedded systems, there is a microcontroller or microprocessor running the application. Embedded systems are generally more basic and rudimentary than microcontrollers since they often do not have the logic to run the system.

Let’s go back to the Lego analogy for a second.  The Legos, when put together, create a larger more complete system. Each Lego however has a specific task and use case. The embedded systems are typically told what to do by the CPU or Central Processing Unit of a computer. You can also get Flash Programmers for STMicroelectronics STM32, BlueNRG, and STM8 MCUs, and STM32MP1 MPUs.

When the CPU tells an embedded system to do something the CPU generally communicates with a microcontroller that is part of the embedded system. Think of the microcontroller as the brains of the embedded system. 

Once the CPU tells the microcontroller to do something the microcontroller then directs the components of the embedded system to execute its specific tasks.

Microcontrollers are very commonly found in the center of most embedded systems and can be thought of as the brains or decision-makers of the embedded system. The MCU is programmed to communicate and direct other components within the embedded system. In a sense, it is the gatekeeper for the embedded system that tells the system what and when to do something.

Working with Embedded Systems and Microcontrollers

When working with embedded systems engineers often run into issues because of the breadth and complexity of modern-day applications. People want more capability in smaller devices.  

The physical engineering that goes into embedded systems nowadays is generally done under a microscope because these systems are so small and complex.
