2. What is a microcontroller?
3.
| SPI | ADC | UART | I2C | |
|---|---|---|---|---|
| a. What do they stand for? | Serial Peripheral Interface | Analog-to-Digital Converter | universal asynchronous receiver/transmitter | Inter-Integrated Circuit |
| b. What are they? | An SPI is a synchronous serial communication interface specification used for short distance communication, primarily in embedded systems. | A device that converts physical quantities into digital numbers to represent the physical quantity. | UART is a computer hardware device that translates data between parallel and serial forms. | I2C is a multi-master, multi-slave, single-ended, serial computer bus. |
| c. What are they useful for? | SPI can be used for Secure Digital Cards and Liquid Crystal Displays (LCD). | It can be used for music recording, digital signal processing, and scientific instruments. | UARTs are used for transmitting and receiving data. | I2C is typically used for attaching lower-speed integrated cirucits to processors and microcontrollers. |
