Deni PETAK from the University of Electronics of Zagreb wrote this thesis which includes references to arduinoos FFT . “In this work will be implemented two versions of DFT transformation and non-recursive (FIR) filters. One version has been developed in MATLAB software tool using Simulink models and Embedded Coder package, while the other hand is written in the C / […]

MicroHTR (Part 8)

Part 1, 2, 3, 4, 5, 6, 7, 8 From the code, one will find the large MenuDriver() function, which is the heart of the menu driver code. Unless you exactly know what you are doing, leave this function unchanged or some harm to your nerves may occur while trying to debug it. It is a pretty compact […]

Students from the Vaughn College, Flushing, NY, USA published a very interesting paper  on Aid Device for Deaf Drivers. [Download here]. They use FFT in order to extract specific sounds such as honks from a noisy environment in order to trigger a vibrating device located in the drivers’s seat. As they used some of the information published on arduinoos.com, […]
