PID-filter routine (2nd try).

Thanks Henrik.

What is the range for the p,i,d variables?

Or is it absolutely project dependant?

Hi,
They are all WORD variables so 0-65535 in theory (each representing a gain of 0-255). However, there is no protection from, or detection of, overflow in the calculations that may be the result of very high gains and very large errors.
