Good Day,
A consensus seems to be emerging among those who know more about pcode
interrupt structure than I. The printf function does indeed disable the
interrupts and run that way for quite a long time. Thus, the servo twitching
seems to be mostly attributable to this disruption of its timed pulses. Thanks
to all who responded (Fred Martin, Randy Sargent, blavery@acslink,
cmcmanis@freegate, richardb@abac, barry@detroit.sgi, and joe.doubek@privy), it
looks like we got this problem pinpointed quickly. Not using printfs in dual
servo routines has been an effective solution. However, don't forget the caps
and high current-capable 6V power supply as well.
