Lecture Topics 📖

There are many limitations to implementing FFT with coding. I went through a lot of trial and error while searching for various materials to implement FFT. I thought that if there were materials that were neatly organized from beginning to end, it would be helpful to many developers who are trying to implement FFT using STM 32, so I created this lecture.

This lecture explains in detail how to implement FFT using DSP Library in STM 32. It explains the entire process from project setup, library installation, code implementation, and result verification using STM32CubeIDE. It explains the process of installing CMSIS's DSP Library, verifying the result using the example included in the library, and the series of processes to actually implement FFT . It will be an opportunity for developers who have experience using STM32 to upgrade one step. Even those who are new to STM32 will be able to understand and utilize STM32 by following the document. This lecture is structured so that you can input a sine wave to the ADC and verify the result.

Wait! ✋ What is FFT?

FFT stands for Fast Fourier Transform, and is mainly used in signal processing in the frequency domain.

ST provides a library for DSP (Digital Signal Processing). Using the DSP Library, you can use various signal processing and mathematical libraries such as FFT, FIR, and IIR filters. If you learn how to install and use the DSP Library through this lecture, you will be able to implement various functions. If there is anything you do not understand in the lecture, please post a question through the Inflearn community or the cafe I run and I will answer it.

📢 Please make sure to check before taking the class!

  • This lecture is a text lecture in electronic document format . All source files explained in the lecture are provided to those who take the lecture. A Windows program for debugging is also provided.
  • In this lecture, we use the NUCLEO-F411RE development board and the compiler tool is STM32CubeIDE v1.9.0.
  • Lecture materials can be downloaded from 'Section 0 - Material Sharing Link - Attachments'.

Expected Questions Q&A 💬

Q. Is there anything I need to prepare to attend the lecture?

This lecture will be conducted on the NUCLEO-F411RE practice board. If you do not have a board, please check the contents first and then purchase the board later and check it on the board.

Q. What program tools do you use?

We use STMCubeIDE v1.9.0, which is provided free of charge by ST. Please install it before taking the course.

Introducing the knowledge sharer ✒️

History

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.
