dead servos

Archiver

Hi
I'm using the stamp BS2 and using the "pulsout" commands but only
one servo will work and I need four servos to work. Why will only
one accept the commands (pulsout). This problem is driving
me "nuts". The servos are not modified to turn continuously.
Please help. Jim

Are all 4 servos hooked to the same pin?
If each have their own pin, you don't expect them to run at the same
time do you? If so, it will take more hardware, Stamps do not
multitask. (could also go straight PIC)

Thanks
I had no idea more than one servo could be run off a single pin.
This has helped with two of the servos but...I won't take up your
time. I've built a quadrupod robot, two servos run the legs and two
give the body a twist to lift the alternate legs off the surface.
Because I needed stability I used continuous servos for tilting not
modified ones like I did for the legs. I think I may have to redo
for the hundred time. I have to ask you something again...sorry! But
is there any way to get a smoother back and forth action from
standard servos? They just slam back and forth not smooth like the
continuous rotation servos. Hey Thanks again Jim.
