Master GPIOs: The Foundation of Embedded Systems!

Welcome to Cocowatt Media, where we simplify embedded systems for everyone! In this video, we dive deep into General-Purpose Input/Output (GPIOs)—one of the most fundamental features of microcontrollers. Whether you're an IoT enthusiast, an automotive engineer, or working on industrial automation, understanding GPIOs is crucial.
🔍 What You'll Learn:
✅ What are GPIOs and why are they important?
✅ How GPIOs work with real-world examples
✅ Different GPIO modes: Input, Output, Alternate Function, and Analog
✅ Best practices for configuring GPIOs efficiently
✅ Deep dive into Infineon Aurix GPIO configuration at the register level
🌟 Stay Tuned! In upcoming videos, we’ll cover GPIOs on other microcontrollers like STM32 and discuss advanced features like pull-up/pull-down resistors, open-drain, and push-pull configurations.
