ARM Cortex-M Processor Programming: Embedded Systems Foundation

Microcontrollers power the modern world, and ARM Cortex-M processors are at the heart of millions of embedded devices. Understanding how to program these processors at a low level is a fundamental skill for any aspiring embedded systems engineer. This text-only course guides you from foundational hardware concepts to writing efficient, low-level C code for ARM Cortex-M microcontrollers. You will gain a clear understanding of processor architecture, memory mapping, and peripheral control without needing complex setups to start. What you'll learn: - Understand ARM Cortex-M architecture, core registers, and the memory map - Write clean embedded C code to configure and control GPIO, timers, and serial interfaces - Configure and manage interrupts using the Nested Vectored Interrupt Controller (NVIC) - Compare bare-metal register manipulation with Hardware Abstraction Layers (HAL) - Apply modern development workflows using open-source compilers and build tools - Implement low-power modes and energy-efficient programming practices You will start by exploring core terminology and internal processor architecture before moving on to hands-on register configuration. The course progresses logically from basic input/output operations to advanced interrupt handling and modern tooling setups. This course is designed for beginners to embedded systems, software developers wanting to move closer to the hardware, and students with a basic grasp of C programming. No prior hardware engineering experience is required. Start your journey into the world of ARM embedded programming today.
