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.
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 …
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.
