Question

Accepted Answer

Interview questions for Embedded Software Engineer including Autosar, function definition, structure and union, microcontroller and microprocessor, and communication protocols.

Autosar is an automotive software architecture standard.
Function definition specifies the code to be executed by a function.
Function declaration specifies the function's name, return type, and parameters.
Structure is a collection of variables of different data types, while union is a collection of variables that share the same memory space.
Enumeration is a user-defined data type consisting of a set of named values.
Microcontroller is a small computer on a single integrated circuit, while microprocessor is a central processing unit of a computer.
Microcontrollers are used in various applications such as robotics, home automation, and automotive systems.
I2C, SPI, and UART are communication protocols used for data transfer between devices.
I2C is used for low-speed communication between microcontrollers and sensors.
SPI is used for high-speed communication between microcontrollers and peripherals.
UART is used for serial communication between microcontrollers and other devices.
