What we have learnt
- Programmable Interval Timers offload timing tasks from the CPU, enhancing performance.
- Serial communication, whether asynchronous or synchronous, is essential for efficient data transmission.
- Analog-to-Digital and Digital-to-Analog converters are critical for enabling communication between the digital and analog worlds.
Key Concepts
- -- Programmable Interval Timer (PIT)
- A device that generates precise timing signals and counts events to offload the CPU.
- -- UART
- Universal Asynchronous Receiver/Transmitter, a common hardware component for asynchronous serial communication.
- -- AnalogtoDigital Converter (ADC)
- A device that converts continuous analog signals into discrete digital values for microprocessors.
- -- DigitaltoAnalog Converter (DAC)
- A device that converts digital signals back into continuous analog voltages or currents.
