Re: CAN troubles with Black Jaguars

One experiment that I will be running tonight is the use of sync groups. My code makes extensive use of sync groups for updating any motors that are linked together, I doubt that it's involved with my problem but I'll grasp at any straw at this point.

Unfortunately, looking at the forums CAN issues seem to be just as rampant this year You'd think we'd learn our lesson.
Sorry to hear you're still having trouble. Do you have LabVIEW installed? Have you read Tutorial 9 on the getting started window in LabVIEW? It describes best practices and may give you some ideas to consider.

What language are you programming in? The C++ implementation saw some improvements this year, to come up to the level that LabVIEW was last year. LabVIEW then surpassed it again (wrt supporting the new Jag firmware features). C++ may support the new features a little later this season. The Jag firmware was released too late to get all the APIs updated to support them in time for kick-off release.
