Comrades;
I have a project with a stepper controlled
needle indicator. I have a simple 8 bit input. I have a maximum
needle speed. The problem is that I have a jerky needle motion. I
have an IIR filter in the software, and you can see the needle jerk in chunks
that resemble binary distances. (IE the needle surges less and less as it
homes in). I need good snappy response, but I need the needle to move
smoothly. Are there any filter gurus out there that can identify my
problem?
Thanks
