Entoptic

OSC Client that spits data based on camera input in the form of an OSC string packet for every frame that look like:

[/A/C1 OSC-string:'0.934847,0.967667,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.918743,0,0,0,0,0.933927,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.983912,0,0,0.981289,0,0,0,0,0,0,0,0.928788,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.954362,0.958915,0,0,0,0,0.906563,0,0,0,0.980445,0,0,0.962922,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.931076,0,0,0.995334,0,0,0,0,0,0,0,0.982881,0,0,0,0,0,0,0,0,0.919610,0,0,0,0,0,0.956571,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0.917023,0,0.931294,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0']

The cell values start at the left corner of the instrument/camera grid and read left to right, top to bottom. The framerate is currently set to 30 frames per second, but will be editable in future versions.
