As per: http://pclapcounter.winnerbb.net/t999-scalextric-apb-and-phidget-pit-detection#4334
, support the following scenario:
1. Option to use Pit-Pro using 2 sensors to limit pit lane speed only.
2. Use Phidget inputs to detect pit stops per lane (car ID). - I believe PC Lap Counter already supports this but putting it here to complete scenario.
So, workflow is:
Car passes first Pit-Pro sensor, car is speed limited. Car pulls into a pit box and stops over the Phidget sensor. Car refuels based on Phidget input lane (car ID). Car leaves pit box, stops refueling. Car passes second Pit-Pro sensor, car is no longer speed limited.
Obviously if car just stops in pit lane anywhere, refueling shouldn't happen (like it does now). See thread above for more information.
