ArduinoPulseGenerator is a simple program for generating pulse sequences using an Arduino. There is an associated GUI that runs on the local computer, or you can simply connect to the Arduino with a serial console (9600 baud) and send it commands. This code has been tested on the ArduinoMega 2560 (timing accuracy ~ ±200 μs) and Arduino Due (timing accuracy ~ ±35 μs); it may work on other Arduino boards.
DyadWaves is an easy-to-use GUI for 1D and 2D wavelet transform. It is pretty basic, with functionality consisting of wavelet transform computation, signal/image approximation, and denoising using up to three transform modes. It contains two executables: dyadwaves and dyadwaves2d for 1D and 2D signal analysis respectively.
