Our testing on SPI recently has focused on verifying brownout recovery, and for SPI that it is very robust, too. Our current understanding: if you have connected the navX MXP USB to the VRM, the SPI bus is reliable even if there is a RoboRio Stage 2 (or even Stage 3) brownout - and other teams are using this interface w/out problem. If the USB/VRM backup power source is not present, the navX MXP will get reset when a Roborio Stage 2 brownout occurs, but our testing has verified that the RoboRio/navX MXP SPI interface recovers in this case, too.

However, for those that experience trouble w/SPI, the Labview library also has a Serial Example, as well.

Let us know if you have trouble with the LabView library. We're here to help.
