Understanding Synchronous and Asynchronous Communication in Embedded Systems

In the world of embedded systems, where efficiency and reliability are paramount, communication between different components plays a crucial role. Whether it's coordinating tasks between microcontrollers or exchanging data between sensors and actuators, the method of communication can greatly impact the performance and functionality of the system. In this blog post, we'll delve into two primary modes of communication: synchronous and asynchronous, exploring their differences, advantages, and use cases.

Top 10 C Coding Interview Questions and Answer (2024)

C is a general-purpose programming language that was created in the early 1970s by Dennis Ritchie at Bell Labs. It has since become one of the most widely used programming languages and has influenced many other languages. C Coding Interview Questions are generally asked in interview.

Write a C program to swap two bits in a bytes.

In the realm of programming, especially in languages like C, bit manipulation is a powerful tool that allows developers to perform various operations at the lowest level of data representation. One interesting task within this domain is swapping two bits within a byte. In this blog, we'll delve into a simple yet insightful C program that accomplishes this bit-swapping magic.

Write a C program to find whether a given number is prime or not

given number is prime or not? A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, a prime number is only divisible by 1 and itself. For example, 2, 3, 5, 7, and 11 are prime numbers, while 4, 6, 8, and 9 are not, as they can be divided evenly by numbers other than 1 and themselves

Understanding AUTOSAR Architecture: A Guide to Automotive Software Integration

AUTOSAR was initiated in 2003 as a collaborative effort between major automotive manufacturers and suppliers. The goal was to establish a common framework for automotive software development, aiming to address the growing complexity of vehicle electronics. Over the years, AUTOSAR has evolved to meet the increasing demands of the automotive industry. Today, it has become a de facto standard, shaping the way vehicle software is developed and integrated.

How Does I2C Communication Works?

Inter-Integrated Circuit (I2C) is a serial communication protocol used to connect microcontrollers and other digital circuits to peripheral devices such as sensors, memory, and other components. It was developed by Philips (now NXP Semiconductors) in the early 1980s and has since become a widely adopted standard in the electronics industry.

How Interrupt Handling Works?

Interrupts are a fundamental part of modern computer systems, allowing for devices and programs to communicate with each other in real time. Interrupts are signals sent by hardware devices or software programs to the processor, indicating that a specific event has occurred and requiring the processor's immediate attention. Interrupts can be triggered by a variety of events, such as user input, a system timer, or data arriving from a network. Interrupt handling is the process of managing these interrupts and responding to them in a timely and efficient manner.

MCAL layer in Autosar

MCAL Layer in Autosar: The MCAL layer is responsible for controlling the microcontroller hardware peripherals, such as ADC, SPI, CAN,LIN,FLS,timers and others. It provides standardized interfaces to the higher-level software layers, such as the device drivers and the operating system. This standardization allows for easier development of automotive software, as software developers do not need to have knowledge of the specific hardware being used.
