Here is the documentation page for that board. You can find the User Manual and CAD resources there.

You can also download their programming tools there, but I try not to use those. Instead, I will use the GNU toolchain.

I’m not sure if I will use this directly, but here are the links for the CMSIS headers for the F4 chip. Those device-specific headers depend on the Arm core headers, such as CMSIS 5 or the latest CMSIS 6.

CMSIS stands for Cortex Microcontroller Software Interface Standard. They provide a standard set of definitions for the underlying hardware.

More details about the chip itself are found in the datasheet and reference manual.

My name is Roeland.

After developing custom small-business software for 25 years, it is time for something new. I am going to learn embedded software engineering.

I have a bachelor’s degree in electrical engineering (specializing in electronics) from 25 years ago, but I have forgotten most of it. I mostly just remember a diode bridge, because that was drilled into us during my final year.

I have also never really used low-level languages like C or Zig. This will be the start of my learning journey, which I will share here. I will start with C, but Zig seems like a great long-term choice since it improves on C. For hardware, I bought an STM32 Nucleo board (NUCLEO-F401RE, €24). My ultimate goal is to write embedded software in Zig, using open-source tools as much as possible.

It may take a while to get there. As a first step, I ordered the book Making Embedded Systems by Elecia White (no affiliation). I am not sure if it is the best place to start, but I saw it recommended online multiple times.

Wish me luck… I will need it!
