Webbotlib Serial Servo Driver Problem
« on: April 17, 2012, 06:13:53 PM »
In Project Designer, the Serial Servo Driver lets you specify servos, but it gives no indication of what position on a serial servo driver the servo should be located at.  8 servos are supported by both the original MiniSSC II board and the Pololu Micro Serial Servo Controller (both of which can use the Mini SSC protocol), though I know other boards have other numbers.

Am I missing something, or are these an incomplete implementation?

(Unrelatedly, I *have* controlled the Mini SSC II with hand code on the Axon in the past, but I have been completely unable to get the Pololu SSC to respond to output from the Axon.)

Am not quite sure I understand what you are asking? Is it: 'Why doesnt Project Designer show you how to connect the servos to the board?' .
If so then: it can't. The MiniSSCV and Pololu protocols that it allows you to choose from are just software protocols supported by a number of different hardware boards but which all work the same. PD doesn't know which one you are using.

Not quite what I was getting at, sorry.  For example, the Mini SSC protocol's 3 byte packets include a servo number.  How do I tell project designer which number corresponds with a servo that I "add" to the Serial Servo Driver?

Thanks!

Its dictated by the order you add them to the list in Project Designer.
