Hi, we made an AIR app that visualizes velocity and position of some high speed motors by using ANE written in C. There are PLC and manufacturer provided dll libs involved, but the general principle is that there's a C++ code that creates a monitoring thread when ANE calls its run(params) function. We poll data from AIR in 20ms intervals and it works pretty nice. When AIR app closes, it calls ANE function that tells C++ class to clean up memory and close monitoring thread. I wasn't involved in writing C++ code and can't tell give you a code snippet for running monitoring thread but I hope this description helped you a bit. Cheers,
