This repository contains the bare minimum to get started with the STM32F103XX microcontroller assembly programming, which features a Cortex-M3 ARM processor.

This repository uses the GNU Compiler Collection arm-none-eabi-gcc with it's subcommands, and a very simple makefile showing various commands needed.

I have had lots of experiences with embedded systems, but through the limited, abstracted window of the Arduino IDE, also I had experience in assembly programming, with the Zilog Z80 80's processor.

So why not try programming an ARM microcontroller with my knowledge in embedded systems and bare assembly programming!

This repository might have many branches as some templates or some scratch code that might use some feature here and there.

I have commented every line of code I could comment on, and for sure will keep adding documentation, references and much more to any code that I write, I don't want anybody to go through the painful process of debugging and to commit pitfalls that I personally did before.
