USO Befehle für Pololu Interface

by **Behle** » Tue 3. Jul 2012, 18:28

Hallo,
ich habe mir für die ersten Gehversuche ein Pololu Servoboard von Robotikhardware bestellt und wollte mal fragen ob jemand bereits Parameter für die USO Schnittstelle erarbeitet hat. Leider habe ich keinen Beitrag zu diesem Thema gefunden bis jetzt. Danke für die Starthilfe.

Hi Behle
Which "Pololu Servoboard" are you refering to? Do you have a Pololu item number? (e.g. Micro Maestro 6-Channel USB Servo Controller (Assembled) = Pololu item #: 1350)

@Behle: Try this with your Pololu Micro Serial Servo Controller in Mini SSC II Mode in the USO section of the x-sim converter:

Set axis 01 as indicated in the picture. Axis 1 = ~a01~ value = (value/2*1)+0

With the command below you can regulate your servo:
Datapacket with axisinformations: ~255~~0~~a01~
255 = start byte (as defined by the pololu board)
0 = servo #
a01 = value of Axis 1 position (8bit resolution) as provided by the x-sim converter

Datapacket sent at simulatorstart and Datapacket sent at simulatorstop you can ignore.

Many thanks so far, i will try. :-)

Is there a reason to use the pololu mode?
