Spectrogram/ PSD Generation using CMSIS DSP

This project aims to implement spectrogram generation using CMSIS DSP in C/C++. It provides both C code for generating spectrograms utilizing CMSIS DSP library APIs (i.e. FFT, Fast Fourier Transform and so on) and Python code for plotting the spectrograms.

Folder Structure

• /python: Contains Python code for plotting spectrograms.
• /cmsis: Contains CMSIS DSP library code for utilized for generating spectrograms.
• /src: Contains source code for implementing and testing the spectrogram generation.

Prerequisites

• CMake
• CMSIS DSP library
• (Optional) Python 3.x/ Jupyter/ Notebook
• (Optional) matplotlib (for Python spectrogram plotting from /python folder)

Usage

1. Clone the repository:

   git clone https://github.com/hissain/dsp-spectrogram.git

2. Build the CMSIS DSP module using script:

   cd dsp-spectrogram
   cd cmsis
   sh clean.sh
   sh build.sh

3. Build the Main app using script:

   cd .. #root
   sh clean.sh
   sh build.sh

4. Run the generated executable to generate spectrogram data. Please refer to src/main.c to understand whats going on and start exploring from there.

    sh run.sh
