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

Clone the repository:

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

Build the CMSIS DSP module using script:

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

Build the Main app using script:
```
cd .. #root
sh clean.sh
sh build.sh
```
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
```
