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!). -- Darren Senn Phone: (408) 479-1521 sinster@scintilla.capitola.ca.us Snail: 1785 Halterman #1 Wasurenaide -- doko e itte mo soko ni anata wa iru yo.
