This course is prepared for Basic Learners.

What you will learn!

  • PWM implementation using STM32 MCU

  • STM32 MCU program implementation

Converting an analog signal into a digital signal?
If you're curious about why, learn it! 🤗

PWM?

PWM stands for Pulse Width Modulation. It is used to generate and change analog signals using digital signals by modulating the width of the pulse. PWM is widely used for control purposes such as motor control and LED brightness control.

Generate PWM signals for your purposes,
 Shall we start together? 🦾

The concept of PWM is very simple. However, the method of implementing PWM varies from MCU to MCU. This lecture will teach you how to implement PWM in ST's STM32 MCU and how to implement PWM for various purposes.

This tutorial explains how to implement PWM with STM32F411. It covers generating and analyzing PWM signals using the NUCLEO-F411RE development board provided by ST. It provides a Windows development program that allows you to change the properties of PWM (frequency, pulse width, dead time, align mode, etc.) and analyze PWM. The compiler tool used is STM32CubeIDE v1.9.0.

💾 Please check before taking the class!

  • This lecture is a text lecture in PDF format and does not provide separate videos.
  • The lecture will be held on the lab board NUCLEO-F411RE .
  • We use STMCubeIDE v1.9.0, which is provided free of charge by ST. Please install it before taking the course.

Lecture Features ✨

#1.
Even for those who are new to ST MCU
It's easy to follow

It explains in detail everything from project creation to source file analysis so that even those who are new to ST MCU can easily follow along. All the source codes explained in the lecture are provided. In addition, the source code for Windows development programs is also provided. We hope that this book will be of great help to those who use PWM.

#2.
Difficult to learn easily
You can learn knowledge

This tutorial explains in detail how to generate PWM on ST's STM32 MCU. It explains what relationships exist between the signals of each PWM when generating multiple PWMs and which mode to use to configure the signal for the purpose. You can generate and test various PWM signals using the provided Windows debugging program.

Introducing the knowledge sharer ✒️

I have been working as a developer for over 20 years in large and small companies and currently run a small business. I have developed an ISP (Image Signal Processing) ASIC for CCTV and many products using FPGA such as OLED inspection equipment and DAQ (Data Acquisition System). In addition to FPGA, I have a lot of experience in FW development (STM32, PIC32, AVR, ATMEGA, etc.), circuit design, and Windows Program.
