How to Program STM32 Microcontrollers: A Complete Guide
If you're just getting into embedded systems, STM32 is one of the best places to start. These chips from STMicroelectronics are used in thousands of real products—from smart watches to robots. But many beginners get stuck early. They don’t know where to begin, which board to choose, or how to write the first bit of working code. And with so many tools and files, it can feel like too much. This guide will help you move past that. You’ll learn how to set up your tools, write your first code, and program an STM32 microcontroller step by step. Even if you’ve never used one before, you’ll finish this guide with working code on real hardware. Step 6: Build and Flash the Program Click the Hammer icon to build Connect the board (ST-Link or USB) Click the Green Bug icon to enter debug mode After upload, click Resume Your LED should now blink! If it doesn’t work: Double-check the pin name Recheck connections Make sure you saved the .ioc file before building STM3...
