I would like to know : how can I do, with LabWindows, for waiting a message (_RDY) from a robot, before sending an other message to my computer?

A french guy. Thanks a lot if you can send me a code exemple.

How is your robot connected to the computer? Serial, Ethernet, GPIB, a built-in control card...?
There are a couple of ways you can do this, but they all depend on the type of connection between them.

Thanks Roberto.
I found a solution in ni.com.
my robot is linked with RS232 (serial).
I'll contact you later because I saw that your specialisation are in DAQ card and others.
thanks again to have sent me an answer.

(if you want to send me your mail address, it will be better for the future).

No problem: you can post your messages to roberto.bozzolo@eltra.net.
Or you can continue posting to the Developer Exchange to have more people responding to your doubts.

Try using a MainCallback fuction, which will loop round continuously without making undue demands on the operating system.

Like this:

int CVICALLBACK MainCallback(int panel, int control, int event, void *callbackData, int eventData1, int eventData2);
int CVICALLBACK MainCallback(int panel, int control, int event, void *callbackData, int eventData1, int eventData2)
{
switch (event)
{
case EVENT_IDLE:
if(ROBOT==_RDY)
{
// Do what needs to be done.
}
break;
}
return 0
}

int main ()
{
LoadPanel (0, "robot.uir", PANEL)
InstallMainCallback (MainCallback, 0, 1);
RunUserInterface ();
return 0;
}
