: Yup, you're right, the MAX function operates on the 16 bit number. So the problem is back to simple scaling.

: The slope is where Nate wants it, all his equation needs is an intercept. The biggest p1_yfilt can ever be is 256. Divide it by 2 and you have no motion (128 counts). its clamped at 128 too. Add 64, and the motor runs.

Correct.

In general, if you want to scale by a factor of n, divide the input by n then add (127-(127/n)) to adjust the intercept.
