I am a newbie to Teesy world. I am trying to do FFT analysis for a vibration signal coming from a 3-axis accelerometer ADXL337. I have found a lot of discussion about FFT on audio signals but unable use this example in my case. My hardware is working to transmit the raw data but I could not find FFT library for Teesy 4.1. If any one can guide me how I can do FFT in my experiment ? If you can share any example code snippet that would be much appreciated.Thanks in advance
