Andy, Yes I will either make my own sequencer/state machine as a custom comp or maybe instead could this not just be done in hal with the right logic? Also this could be done in ladder logic I think. Up to now I just put all of my logic in hal and avoided ladder. But maybe doing this all in hal would be considered too tedious vs a custom comp?
So this prompts another question. What is the difference between a custom comp vs one that is built in?
