I want to change the way the step threshold is used in pi.c. Currently the
servo gets unlocked and servo code is skipped.This will allow the clock to
step, which I don't want to happen. I changed the code to:
Limit the master_offset to the range (+/-) of the threshold.Don't unlock the
servo.Process the limited master_offset with the servo.
I have tested this code and it works great to remove jitter due to network
traffic.The value of the step threshold can easily be determined by performing
a baseline run. If modifying the existing could is frowned upon, a new
configuration parameter could be added called "max_offset" to perform the same
function.
