Microcontroller Peripherals

This lecture covers the architecture of MCU-based computer systems, focusing on common peripherals such as analog comparators, ADC, servo motors, infrared remote controls, and keyboard controllers. It explains how microcontrollers interface with external devices through buses, control, and data buses. The lecture also delves into the operation of ADC, servo motor control using PWM, and keyboard scanning techniques. Additionally, it discusses the communication protocols for peripherals, including the 1-wire protocol and IR signal modulation. The importance of precise timings, pulse width modulation, and peripheral access methods are highlighted, along with the role of internal modules in interfacing with various devices and sensors.
