Custom Device Creation

[MitchD319]

I am trying to create a custom device which makes it easy for a user to configure many digital output channels. My device currently initializes in VeriStand without any issues. I have a heirarchical design with an "Output Module 1" folder containing 32 channels. I have added the propeties Output Mode (U16) and Enable State (Boolean) to each channel. The problem is that I don't know how to set the values of these properties in the LabView design. I have tried using the Set Item Property VI to write a new value to each property without any luck. I have tried various other VIs too, but none seem set the value of the property. I get a response from changing the values on the "front panel" page in VeriStand's system explorer, but when I click on a channel to look at the properties, nothing has changed.

I followed NI's step by step custom device guide http://zone.ni.com/reference/en-XX/help/372846J-01/veristandmerge/cust_device_overview/.

My hunch is that my unfamiliarity with node pointers is causing me trouble. Does anybody have some insight into this issue?

Hi MitchD319,

If I understand your question correctly, the following resource should be helpful:

Sorry for the late reply. It turns out that I wasn't understanding pointer nodes correctly. In the initialization code the node refers to channels. I was trying to use the reference as input to the channel parent and then use feed the children reference to the channels.
