AP_InternalError holds information about "should not happen" errors
|
|
that have occured within ArduPilot. This covers things like code
|
|
paths that should not be crossed or pointers being null when they
|
|
really, really shouldn't be. It does NOT cover things like losing
|
|
GPS lock at inopportune times - that's just bad luck, not bad
|
|
programming.
