ReadDigChan_ChangeDetection_DigFilter problem with PCI6515

[losvil]

Hello,

I'm using ReadDigChan_ChangeDetection_DigFilter demo program to test PCI6515.

I'm testing port0 with a 9V battery. Often when I open the contact from GND and one pin of port0, the board (or the demo program) doesn't generete the event, and I continue to see the signal ON, but there is no connection on pin ?

Why this behavior?

Thanks

Giovanni

Hi Giovanni

what software are you using? CVI?

If you test the hardware using MAX, do you obtain the same behaviour? In this case it could be a driver installation problem

Hi,

I'm using  ReadDigChan_ChangeDetection_DigFilter a c# demo project.

This demo use the ChangeDetection function of PCI6516 board. The digital inputs are not readed in polling mode, but "only when they change".

In MAX I can test the inputs, but I think that the test is "in polling mode".

Regards

Giovanni
