Code in support of the 'FFT: Fun with Fourier Transforms' guide on the Adafruit learning system.
martin-ger:
- Added sampling code for the ESP8266 and the ESP32. Connect e.g. a MAX4466 to the A0 ADC.
- Changed serial baudrate to 115200
- Max. sampling rate now 40000Hz (ESP8266 hardly manages 10000Hz, ESP32 is better)
Requires Python 2.7 with:
- cmake
- matplotlib, a library for plotting data.
- NumPy, a library for numeric computing.
- PySide, a python binding to the Qt user interface library.
- pySerial, a library for serial code IO.
