wtf is stm32f401_eeprom_driver?

This project is a driver for reading and writing data to an external EEPROM memory chip, built for the STM32F401 microcontroller. EEPROM is a small type of storage that remembers data even when the device loses power. If you are building a hardware project and need to save settings, calibration values, or small amounts of data permanently, this code handles the communication to make that happen. What makes this project unusual is that it is written entirely in Assembly language. Most microcontroller software is written in higher-level languages like C, which are easier for humans to read and write. Assembly is a step above raw machine code, speaking almost directly to the hardware's processor. Writing a complete driver this way requires deep knowledge of the chip's inner workings, but it results in extremely efficient code with no wasted memory or processing power. At a high level, the code works by setting up specific pins on the microcontroller to talk to the EEPROM chip using a communication protocol called I2C. I2C is a standard way for chips to chat with each other using just two wires. The driver configures these pins, sends an address to the EEPROM chip to tell it where to look, and then either sends a piece of data to be stored there or asks for data to be read back. This project is aimed at embedded systems engineers, hardware hackers, and reverse engineering students. For example, if you are building a custom sensor device and want it to remember its configuration after being unplugged, you might use an EEPROM chip. While most developers would grab a pre-built library to communicate with it, someone might use this project to learn how the hardware actually works at the lowest level, or to reverse engineer the code to understand exactly what a microcontroller is doing. The code itself is a technical reference rather than a plug-and-play solution. The README is sparse and does not provide instructions for beginners, so it assumes you already know how to compile and flash Assembly code onto an STM32 board.
