Re: Worried about high CPU usage in CRIO

It does not solve the total CPU bandwidth issues but you can prioritize activities on the cRIO. We run the DS comms in task with higher priority than the camera so the camera gets the remaining bandwidth AFTER the comms, motors and sensors have been serviced. We work in C++ and use the native VxWorks (OS in the cRIO) API for doing this but I believe LabView, Java and WPI/C++ have APIs to create independent tasks and set their relative priorities.

We are processing images at about 10Hz (on the cRIO) which (we hope) is fast enough.

HTH
