Register-Level Understanding

A beginner should eventually understand how firmware interacts with hardware registers.

For example, configuring a GPIO pin may involve:

  1. Enabling the peripheral clock.
  2. Selecting the pin mode.
  3. Configuring direction.
  4. Writing or reading the GPIO register.

This knowledge is essential for understanding what happens underneath high-level driver libraries.

GPIO, Timers, PWM and ADC

Microcontroller peripherals form the foundation of embedded programming.

GPIO

GPIO allows firmware to control or read digital signals.

Typical applications include:

  • LED control
  • Button input
