Microcontroller Development Basics: From GPIO to Peripheral Drivers

1. Microcontroller Overview

A Microcontroller Unit (MCU) is a miniature computer that integrates CPU, memory, and peripheral interfaces on a single chip.

2. GPIO Configuration

GPIO (General Purpose Input/Output) is the most basic peripheral of a microcontroller, configurable as input or output mode.

3. Timers and Interrupts

Timers are used to generate precise time delays and timer interrupts, making them one of the most commonly used peripherals in microcontroller development.

4. Serial Communication

UART serial communication is a common method for microcontrollers to communicate with external devices, supporting full-duplex communication.
