An RTOS
Before we talk about an RTOS, let's talk briefly about embedded software in the next section.
Embedded software
Enterprise or traditional software applications are usually written in a high-level programming language (human-readable languages) such as C, C++, Java, and C#. Then, these high-level programming languages are converted into a low-level machine-readable language, or in short, they are converted into a series of 0s and 1s at the end. Computers understand only binary data (0s and 1s).
When it comes to embedded software that runs on a microcontroller, it is the same. You need IoT device application code to be converted into 0s and 1s, and then the microcontroller or the microprocessor of the microcontroller will load that program into the memory of the microcontroller and start executing it.
If you have played around with the Arduino microcontroller before, I am sure you realize how it is easy to write software that runs on it and interacts with different...
