BS2, PULSOUT, and servo question
Archiver
Posts: 46,084
hi....newbie here,
connection a modified servo to the BOE and bs2 , i tried to vary
the "pulsout pin, rate" from pretty much zero to well inot the
900's,....and it always turns the same way.
the only way i can get it to turn the other direction is to use
smaaaalll negative fractions... like (-1/32)
what am i doing wrong and/or what values do you guys use?
thanks fer the help!

can't remember what I use for the BS2SX, but its somewhere in the 1000 range
for neutral, and the BS2E is around 320 using a Futaba servo.
Are you using a variable for the PULSOUT statement? If so, you are proabably
using a byte-sized variable (holds value of 0-255) instead of a word-sized
variable (holds value 0-65525).

You may not be going high enough to get it to go the other way. Try using a
larger value. An older pair of servos I have takes 1200 and 650 for forward
and reverse.
