Unions in C are used to store different data types in the same memory location.

• Unions are used to save memory by allowing different data types to share the same memory location.

• They are commonly used in situations where only one of the data types needs to be accessed at a time.

• For example, a union can be used to store an integer and a float, with only one being accessed depending on the context.

A 120-ohm resistor is used in the CAN protocol to match the characteristic impedance of the network and reduce signal reflections.

• The 120-ohm resistor helps to match the characteristic impedance of the CAN network, which is typically 120 ohms.

• It reduces signal reflections that can cause data corruption and communication errors.

• The resistor is placed at both ends of the CAN bus to ensure proper termination.

• Without the resistor, the signal quality and reliability of the CAN com...read more

PWM is a technique used to encode analog signal using digital pulses of varying widths.

• PWM is commonly used in controlling the speed of motors, brightness of LEDs, and audio signals.

• It works by varying the width of the pulse in a fixed time period, known as the duty cycle.

• The average voltage of the signal is determined by the duty cycle - higher duty cycle means higher average voltage.

• PWM is achieved by rapidly switching a digital signal on and off at a specific frequency.

• It ...read more

The volatile keyword in programming is used to indicate that a variable's value can be changed unexpectedly.

• Used to prevent compiler optimizations that assume variable values do not change outside of the program

• Commonly used for variables that are modified by hardware or other threads

• Example: volatile int sensorValue; // variable updated by external sensor

Bus off is a state where a node on a bus is disabled due to errors. I2C and SPI are different communication protocols used in electronics.

• Bus off is a state in CAN bus where a node is disabled due to errors.

• I2C (Inter-Integrated Circuit) is a synchronous serial communication protocol commonly used for communication between integrated circuits.

• SPI (Serial Peripheral Interface) is another synchronous serial communication protocol used for communication between microcontrollers ...read more

I have used various tools for architecture modeling, such as UML, BPMN, and ER diagrams.

• UML (Unified Modeling Language) is a widely used tool for architecture modeling, which includes various diagrams like class diagrams, sequence diagrams, and activity diagrams.

• Collaborated with cross-functional teams to ensure project success

Startup code sequence refers to the order in which code is executed when a program is launched.

• Startup code sequence typically involves initializing variables, setting up memory, and executing any necessary setup functions.

• Examples of startup code sequence include setting up hardware registers in embedded systems, initializing global variables in C programs, and loading configuration files in web applications.

CAN protocol is a communication protocol used in automotive and industrial applications. CAN frame structure includes ID, data, and control bits.

• CAN protocol is used for high-speed communication between electronic control units (ECUs) in vehicles.

• CAN frame structure consists of an ID field, data field, and control bits like CRC and ACK.

• Examples of UDS services include reading and writing diagnostic data, accessing ECU information, and performing routine tests.

Lathe machines are tools used for shaping and cutting materials such as metal and wood.

• Lathe machines rotate a workpiece on its axis while a cutting tool is applied to shape it.

• They can be used for various operations such as drilling, knurling, and sanding.

• There are different types of lathe machines such as engine lathes, turret lathes, and CNC lathes.

• Lathe machines are commonly used in manufacturing and metalworking industries.
