# Stage 1: is the panel delivering events to us at all?

# Stage 2: which direction and how many contacts does lisgd see?

# 0=DU (down-to-up) 1=UD 2=LR (left-to-right) 3=RL (right-to-left)
|
||
|
|
#
|

# If Cfg and Evt agree on s= but differ on f=, your panel reports more contacts
|

# than you configured -- add them to FINGER_COUNTS in the config.
