Brain displays just User Display

Has anyone seen this? We saw this once last year but twice this time. Each time [x] does not work. Had to pull battery for the reset. Seems to work fine after that. Should it some some error message or something? Just blank each time. Thanks.


Hi surgeon,

Did this error occur while running a build in program (such as Driver Control or Autopilot), or did this occur with a custom user program (from ROBOTC, Modkit, etc)?

Hi Art, It was with custom user program from RobotC.


This is odd behavior for a program to cause indeed; please send a copy of the code with as much detailed information on the issue as possible to use directly via and we’ll be more than happy to look into this further for you.
