Do something while checkbox is checked - did not work

Recommended Posts

Hello Autoit community,

I try to control a syringe pump via rs232. To do this, I have to send the syringe pump the command "suck 300 ml" (/ 1OA300R) and send the command "Press the syringe together to zero ml of contents" (/ 10A0R).

The syringe pump should always suck or pump with a change of edge (0.2 Hz from a function generator). And the whole sucking and pumping should only begin when a checkbox of Gui is pressed.

I thought you could solve this:

 

While 1
    $nMsg = GUIGetMsg()
    $CTS_PinState = _CommAPI_IsOnCTS ($gFile)                       ;get true or false from CTS-Pin
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

        Case $Checkbox1
            If GUICtrlRead($Checkbox1) = $GUI_CHECKED Then
                If $CTS_PinState == True And $CTS_PinStateOld == False Then         ;edge
                    $CTS_PinStateOld = $CTS_PinState
                    _CommAPI_TransmitData($hFile, @crlf&"/1OA300R")
                ElseIf $CTS_PinState = False And $CTS_PinStateOld == True Then      ;edge
                    $CTS_PinStateOld = $CTS_PinState
                    _CommAPI_TransmitData($hFile, @crlf&"/1OA0R")
                EndIf
        EndIf



But unfortunately, the code works only if I press the checkbox exactly at a flank change.
It seems to me as if I ask the checkbox event incorrectly.

I hope you can help me.

Thanks and regards

I am unsure what you mean here and what exactly you are expecting?
It makes sense that the code only is executed at the time the checkbock gets checked as that is what you are telling it to do in the script.

Hi Jos,

 

I would like to check the condition of the checkbox. If this "checked" should run a subroutine that constantly queries the CTS pin. The CTS pin delivers a square wave signal at 0.2 Hz. The value of the CTS pin can be true and false. And always just when a flank change happens on the CTS pin, the pump suck or squeeze. The pump should suck and press until the checkbox is "unchecked" again.

 

Ok, somewhat complicated. In simpler terms, the pump should suck and pump permanently while the checkbox is active

Something like this?

While 1
    $nMsg = GUIGetMsg()
    $CTS_PinState = _CommAPI_IsOnCTS($gFile) ;get true or false from CTS-Pin
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    If GUICtrlRead($Checkbox1) = $GUI_CHECKED Then
        If $CTS_PinState = True And $CTS_PinStateOld = False Then ;edge
            $CTS_PinStateOld = $CTS_PinState
            _CommAPI_TransmitData($hFile, @CRLF & "/1OA300R")
        ElseIf $CTS_PinState = False And $CTS_PinStateOld = True Then ;edge
            $CTS_PinStateOld = $CTS_PinState
            _CommAPI_TransmitData($hFile, @CRLF & "/1OA0R")
        EndIf
    EndIf
WEnd

Tidy broken ? :)

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
