🔥 How Linux Talks to Hardware? Linux Device Drivers Explained | Complete Beginner Guide 🚀
🚀 Linux Device Driver Introduction
Linux Device Drivers are the bridge between the Linux Kernel and hardware devices. They enable communication with peripherals such as GPIOs, UART, SPI, I2C, USB devices, Network Interfaces, Storage Controllers, Cameras, Sensors, and many more.
In this session, you'll learn:
✅ What is a Linux Device Driver?
✅ Linux Driver Architecture
✅ Character, Block & Network Drivers
✅ File Operations (open, read, write, ioctl)
✅ Interrupt Handling (IRQ)
✅ DMA (Direct Memory Access)
✅ Memory-Mapped I/O (MMIO)
✅ Loadable Kernel Modules (LKM)
✅ Device Tree Basics
✅ Driver Development Flow
✅ Real-World Driver Examples
Whether you're an Embedded Engineer, Firmware Developer, Linux Professional, or aspiring Kernel Developer, understanding device drivers is essential for building robust embedded and semiconductor solutions.
