Re: Worried about high CPU usage in CRIO

I finally got some time to look into this. My original numbers seem to be off slightly. The graph of my driver station has an extended scale below 0. (I hope that the scale matches the graph.) Disabling various things and even modifying the framework to control the loops, allowed me to bring the CPU utilization down to well below 10%. I tested the default framework, acquiring but not processing images, sending data to the default data to the dashboard, and a bit of extra code only hit 25% CPU utilization on the first frc-cRIO. I did manage to confirm that the dashboard compiling and sending VI was a significant portion of that 25%.

There seems to be a fair amount of CPU left for vision processing.
