Microcontroller Tutorials with Code from Scratch

Learn STM32, ESP32, and embedded systems by writing code from scratch using datasheets and reference manuals. All tutorials are tested on actual hardware to help you build reliable, real-world projects with full control and understanding.

What’s New in STM32

SPI using Registers in STM32

This tutorial will cover how to use SPI using Registers in STM32. We will see how can we send and receive data in master mode..
