Over the last two decades, I’ve worked on embedded systems projects ranging from automotive ECUs and industrial automation controllers to IoT devices and medical instruments. One pattern I’ve seen repeatedly is this: teams love the idea of agility, but they struggle when trying to apply pure Scrum in environments where hardware, firmware, and software all […]
Understanding stack operations is crucial for developing efficient and robust microcontroller applications. The 8051 microcontroller, a popular choice for embedded systems, offers a powerful stack mechanism that plays a vital role in managing program flow and data storage. In this comprehensive guide, we’ll delve deep into the intricacies of 8051 stack operations, exploring how to […]

New Software programmers often get confused with the concept of interrupts. It is very simple to understand if we consider an analogy with our daily tasks. Assume you are cooking food and you get a phone call. What do you do in such situation? You first checks who is calling? If the caller is not […]
Switches are very important part of machine interface. Pressing horn in your car or hitting the call button on your cell phone, we interact with daily various machines through switches. There are varieties of switches we press, rotate or touch daily. Your funky radio jumps 2 or 3 channels ahead when you press tuning button only once. […]
Interrupt handling in 8051 is very simple. To learn interrupts handling in 8051 microcontroller; first of all we must understand what different types of interrupts available in 8051 microcontroller. Types of interrupts in 8051 External hardware interrupt – INT0 External hardware interrupt – INT1 Timer 0 overflow interrupt – TF0 Timer 1 overflow interrupt – […]
Memory is a costly comodity in the world of embedded software development. Software programmers often need to optimize the code to reduce memory utilization or to increase speed of execution. It is the last step in software development, but this is not always in the case of embedded system development. To save the cost of […]
