Differentiate between microprocessors and microcontrollers and list the selection criteria for an embedded application.

Explain the purpose of GPIO, timers, interrupts, serial interfaces (UART, I2C, SPI) and ADC in embedded designs.

Write or trace a simple embedded program flow (initialise port, read input, drive output) and describe what each line does.

Explain the working principle, loading effect and typical accuracy of analog multimeters, digital multimeters, CROs and function generators.

Calculate measurement error from voltmeter sensitivity, tolerance and resolution, and interpret a displayed reading correctly.
