Ok I've taken about 6m onths off from this project,
but I'm back at it again. When I left off I was stuck at how to get my
application running on a Verdex under JamVM to communicate ot a Servo. I
have a robostix which I plan to use to communicate to a number
of servos. When I last emailled this group about this problem someone
suggested I use i2c-io. how ever this looks to be a command line
application, which means that the communication from a Java aplication would be
slow. So controlling servos at a high rate would be cumbersome The
servos will be controlling a UAV Throtle, Airelons left and right, rudder,
elevator, camera pan and tilt. The pan an tilt might only see a few
instructions a second but the others would see between 1 and 50 a second.
At the very least each would be seeing a couple per second.
1) So my first question has anyone come up with a
better solution in the past 6 months?
Next if the anwser is no then how about
this:
2) I have not yet flashed the robostix with
the i2c-io.hex. I'm assumming this application listens to the i2c
interface for a set of commands and a seperate i2c-io application runs on the
verdex, which when executed passes some message over i2c interface to the
robostix that then executes the command on the robostix. Ff this is the
case then could I use java to communicate over th i2c interface
directly.
3) If so how easy is that?
4) Are there any examples of how to do
this?
5) Is the command set for the i2c-io that runs on
the robostix itself defined anywhere?
Thanks,
Michael
