Execution of a C Program

Once you have successfully compiled the C program, it creates an executable file. You execute/run the program. The question arises is “How does this program gets run on the target?”. Target can be both a Microprocessor or Microcontroller. In order to understand this, we need to first understand little bit about the Central Processing Unit

Dissecting a Simple C Program

What constitutes a simple C program? Let’s understand bit more in detail. Comments Comment is not actually part of the program code, in that it is not telling the computer to do anything. It is simply a comment, and it is there to remind you, or someone else reading your code, what the program does.

Creating C Programs

There are three fundamental stages, or processes, in the creation of any C program: Editing Editing is the process of creating and modifying C source code — the name given to the program instructions you write. You can use any integrated development environment (IDE) such as Eclipse or Visual Studio Code for writing, managing, developing,

Why learning C is important for Embedded Systems?

Learning C is particularly important for embedded systems for several compelling reasons: In conclusion, learning C is crucial for embedded systems development because it provides the necessary tools to interact with hardware, optimize code for limited resources, and meet the real-time requirements often associated with embedded applications. Whether you’re working on IoT devices, microcontrollers, or

Introduction to ARM Architecture

After getting to know different microcontroller architectures, its time to explore the ARM architecture as we are going to use STM32 microcontroller in this course which is of ARM architecture. ARM (Advanced RISC Machines) is a family of processor architectures developed by ARM. It is one of the most widely used and popular processor architectures

Debouncing considerations when reading input from switch

Mechanical switches and buttons can have bouncing or chatter when they are pressed or released. During this time, the electrical contacts inside the switch make and break contact rapidly before settling into a stable state. This bouncing can generate multiple pulses or transitions in a short period.

Debouncing is an essential consideration when reading digital input from switches, buttons, or other mechanical contacts in embedded systems or digital circuits. Failing to debounce inputs properly can lead to erratic behavior and false readings.
