    Hello everybody.

    Help needed.

    I try to set up a pololu micor maestro device with the uso and absolutely no success. The indicator lights show no reaction whatever settings I have tried. Sometimes there are parsererrors, but they are related to com ports which are not used. Very confusing.

    Regards

    A little more details please mate,
    One thing to try is to delete all comports configs in xsim then reactivate the one ya using.
    As for commands, let me remember the command ~~255~~9~~a01~ moves servo 9 which is on port 1 (180deg) to position a01
    If this helped good or as state a little more details.

    Hi eaorobbie,

    thank you for the answer. I have deleted the unused ports but the result is, that I now will send the details ...

    Sender works with TestTablet set in automatic mode for ch 21. Force profiler receives on #21 the moving Signal between -1000 and +1000. Math works and shows beautiful shark teeth. Output is on com2 (the controller command port as indicated in the Geräte-Manager). Axis 1 (~a01~) value ( ..1*1)+0, 8 bit resolution, dezimal output, selected port: com2, 9600,n,8,1, no start/endpacket, informationpacket:~255~~2~~a01~, 33 ms

    The pololu board works perfect with the Pololu Software.
    After a simple reconnection of the board and a start of the profiler happens this:
    The green leds are on and show no flickering. The yellow one shows a short flash (manual: no servo active?) every second. Not the smallest grumble from any servo.


    Regards

    ... and now it seems to work. But after some seconds there the error led gets red and indicates a serial protocol error. Servo on ch2 stops, moves quick and goes on.
