Re: ANNOUNCING: navX MXP Robotics Navigation Sensor

But it's a bit early in the investigation process to tell.

We've setup a LabView SPI longevity test here at Kauai Labs, and will try to reproduce the issue - and if we can reproduce it, we'll gather as much info as we can and inform National Instruments of the details - and post what we know on this thread.

Until we find out where the problem lies and how to resolve it, you might consider using the TTL UART or USB interfaces instead.
Follow-up questions: What update rate (in Hz) are you using w/the navX MXP - this'll help make sure our testing here is as close as possible to your situation. Also, what is your overall CPU % (average) when running your robot software?
