Trigger
VR, HALL, HALL

Cam actuators
- manually actuated outputs actuate the cam, but
- not configured properly
Trigger errors
Engine is running well, but trigger error is lit continuously...
- sectrig position measurement ?
- position change not seen even when manually actuated (and cam obviously moving)
- third trig measurement ?
- position change not seen even when manually actuated (and cam obviously moving)
triggerlog ?
Capture triggerlog:
- start capture triggerlog (preferrably 115200 baud)
- starting engine (this should be in the log)
- advancing cam (actuating manually)
- engine might stop because of this
- don't forget to name/annotate the log, taking note of what is happening, so it's possible to find (among dozens of other)
- preferrably a vemslog should be captured with similar sequence (it's another attempt, as it's not possible to capture 60-2 triggerlog and vemslog at the same time because of baudrate limitation)
