If you have worked with the C++ STL library, you have definitely encountered the error “Vector subscript out of range.” This occurs when attempting to access an element in a std::vector using an invalid index. This often leads to undefined behavior, crashes, or runtime errors. In this article, we will discuss the causes of this […]

In my previous blog post, I discussed how to blink an LED using the STM32 microcontroller. In this tutorial, we will learn how to configure STM32 button input using STM32CubeMX and control an LED based on button presses. Understanding how to read a button input is essential for building interactive STM32 applications. For this tutorial,

Nowadays, most microcontrollers have two or more features integrated into one pin. This means a single pin can have more than one functionality. Such a pin is known as a multifunction pin. All microcontroller manufacturers include a table in the device’s datasheet. This table lists each pin’s features and provides simple instructions to set up

In embedded systems, reliable data communication is very important. Whether you are debugging firmware, interfacing sensors, or building production systems, serial communication plays a central role. Among all serial protocols, UART (Universal Asynchronous Receiver/Transmitter) is the most widely used due to its simplicity, flexibility, and minimal hardware requirements. This article is the first part of

Design pattern consists of two important words “Design” and “pattern”. Here design means software design and pattern means same type of problems (commonly occurring problems in software design). So, design pattern is a general, reusable solution to commonly occurring problems in software design. They are like ready-made blueprints that you can customize to solve a
