- What's wrong with just using an RC filter to scrag the high frequency
- components of the signal? When you reload the entire shift register
- chain, you'll presumably do it in a tight loop. This will create a
- high frequency glitch in all the outputs. If you use a low-pass filter
- on the output of all the shift registers, things should work pretty
- well. It shouldn't cost more than $1 for eight caps and resistors.
- You just have to worry about space. Luckily these components can be
- packed pretty tightly, or even used as part of the wiring to the
- motor (0 PCB space that way!).
