Twiddle-factor-based DFT for microcontrollers
This version of DFT algorithm has been tested with success on a various microcontrollers (AVR – including ATtiny13, STM32 and ESP8266). The code is relatively simple and short what makes it easy to port to other programming languages / microcontrollers. In this tutorial I will open the black-box and show you some practical information about how this algorithm works and how to use … Read more
