Overview:
Refer to the Instructables page:
[tbd]
Todo:
Sketch -- Remove String objects -- Make all variables global and reuse indices when necessary (Or verify that the compiler uses the fastest access mode possible) -- Possibly code sample functions that are optimized for channel arrangements (e.g., remove extraneous shifting, OR'ing and calls) -- Use a decreasing call to malloc() during setup() to find the largest usable array. -- Port to Pi & Edison
server.js -- Remove express, formidable and morgan to make the code smaller and reduce dependencies. -- Reloads of the client '/' and '/index.html' should reset the serial port. This would allow interrupting the hardware via client.
index.html -- Add time-axes and markers -- Try HTML5 server-sent events instead of socket.io
