Teensy-3.6-CMSIS_DSP-FIR-filter

This project combines the use of MATLAB, a Teensy 3.6 MCU, the CMSIS-DSP Library, and a Micro SD card to create an FIR Filter.

How it works:

Using MATLAB, a wave file is exported as a binary file, placed in a SD card, then read and filtered by the Teensy 3.6. The output file is, in turn, imported into MATLAB and played back to confirm that the data has been filtered.

What is included

1. Instructions
2. Teensy 3.6 code
3. Required CMSIS_DSP library files, modified to work with the Arduino IDE
4. MATLAB scripts to export and import data.
5. Sample wave file.

Enjoy!
