Flash Over-the-Air (FOTA) updates are a method of remotely updating a vehicle’s software and firmware through a wireless connection, typically via cellular or Wi-Fi networks. This technology allows automakers to deliver software updates, bug fixes, and new features to vehicles without requiring them to be physically brought to a dealership or service center.
Drive By Wire technology traces its roots back to the aerospace industry, where electronic controls were used to maneuver aircraft. The concept was then adapted for automotive applications, initially finding its way into high-end sports cars and luxury vehicles. Over the years, it has trickled down to more affordable models, becoming increasingly common.
Embedded systems are at the heart of numerous electronic devices we encounter in our daily lives, from smartphones and smart appliances to automotive systems and industrial machinery. One essential component of these systems is the timer, a versatile tool that plays a crucial role in managing and coordinating various tasks. In this blog post, we will delve into the world of timers in embedded systems, exploring their functionality, applications, and inner workings.
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.
Watchdog Timer: The Secret to Reliable System Operation When it comes to designing embedded systems and other applications where uptime and reliability are critical, a watchdog timer can be a powerful tool. In this post, we’ll take a closer look at what watchdog timers are, how they work, and why they’re so important for reliable …
Bit manipulation in C language. In this blog, we will see How to Set, Clear, and Toggle a bit in C language using the Bitwise operator. How to find a particular bit is set or clear.
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.
Understanding Big-Endian and Little-Endian Byte Order
When we talk about computer memory, we refer to it as a collection of bytes, each of which is assigned a unique address. In computing, the order in which these bytes are stored is called byte order, and there are two different ways to do it: big-endian and little-endian.
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.
