NOISE

Note: This code is not currently compiling.

NOISE is a lattice random walker simulator. The implementation allows arbitrary number of random walkers and dimension. The system consists of a concentric pair of hypercubes with the bigger one forming the bounding box and obeys periodic boundary conditions. This implementation cross-compiles on an Arduino compatible microcontroller as well as a PC system. When compiled on a microcontroller, the code can be used to generate Poisson Noise signals on any available digital pin. The compiled PC system can be used as an emulator or a stand alone application.

The random walkers in the HyperCube emit a HIGH signal, whenever a random walker passes through the smaller concentric cube. The inspiration behind this model was to crudely simulate diffusive fluorescent particles passing through a confocal volume. Outside the confocal volume (or the smaller hypercube), the signal emitted by the random walkers is LOW.

The file macros.hpp contains the macros the are used to enable/disable features and control the build environment.

→ For PC Systems, build using gcc:

g++ -std=c++11 main.cpp -o noise

Execute:

./noise <optional-name>
