    I don't have that much experience with ScriptComunicator or QT
    I noticed that the "ScriptTimer" accuracy varies a lot.
    When the timer is set to 100ms the timer will fire 10ms to late.
    It also varies by +- 5 ~ 20 ms.
    The QTtimer class has a function called "timerType"

    Is it possible to add that function to ScriptComunicator?

    In "scriptTimer.h" there is a list of Q_invocable`s
    In there, add the function "setTimerType"

    It is something like that but I'm not skilled enough to do so.

    Kind regards.

    Hi,

    I uploaded (File/Test) a prerelease that contains the new timer function setTimerType(String type). Possible values for type are:
    - PreciseTimer (Precise timers try to keep millisecond accuracy)
    - CoarseTimer (Coarse timers try to keep accuracy within 5% of the desired interval
    - VeryCoarseTimer (Very coarse timers only keep full second accuracy)

    But I don't think that this will help. A few years ago I wrote a device simulator with ScriptCommunicator. There I had the same effect (on Windows) that you described. I tried several thinks but nothing worked. Then I executed it on a Linux PC and the timing was perfect.

    Maybe you should execute your script on a Linux PC too.

    Regards,
    Stefan
