IRQ 07 in LabView

[WSalas]

Hi,

I have a GPS embedded in a PC-104 and it is associated with the IQR 07, I can read the Data Register using the In Port funtion of the LabView, but this is very confusing, I would use interruptions in this case the IRQ 07 to synchronize the reading of this register, someone might say as I do this?

Hi WSalas,

I don't understand very well how the communications works on PC-104. But you can try to register a user event for your device, using Register Event Callback, and with this you can try get a synchronism with your received messages. See below a documentation about Register Event Callback.

https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/functions/register-event-callback.html

Take a look on the Example ActiveX Event Callback for IE VI, it creates a user event when the Activex try to access a forbidden address.

If you can, please provide us more information about the communication between your computer a and your PC-104.

I hope it may help you.

Regards,
