L10: General purpose input output in a microcontroller

Welcome to Lecture 10 of the course “Embedded C Programming” by Prof. Nitin Chandrachoodan.
Full Course: https://study.iitm.ac.in/es/course_pages/CS2101.html

Video Overview
Explore the fundamentals of General Purpose Input/Output (GPIO) in microcontrollers in this detailed lecture. Understand how GPIO serves as the interface between the CPU and external devices, and learn about memory maps, buses, and their roles in microcontroller operation. Dive into pin configuration, input/output modes, and the differences between analog and digital signals. The session also covers pull-up and pull-down resistors, open-drain connections, and explains how the Hardware Abstraction Layer (HAL) simplifies GPIO programming while ensuring code portability across platforms.
