How do I implement my own transfer function?
LabVIEW has lots of built-in controls and filters, but I want my own. I want to send data I collect through a transfer function of my own specification, such as a second order where I can specify frequency and damping. Or even something much higher-order. But I cannot figure it out. I played with the H(z) d... 11 Nov 2008 23:00

Reading controller data into LabVIEW through serial connections tocontrollers?
I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar?

How can I use LabVIEW to refresh the USB port?
In my LabVIEW program I am using USB to communicate with some equipment. The USB connection might be a little unstable. Sometimes the LabVIEW program gets stoked and there is nothing I can do to make it running again. Only I can pull out the USB cable from the PC and then put it back in. Then LabVIEW is running ag... 15 Aug 2008 07:54

Event handling using CAN?
I am aware of how to make LabView respond to user interface events (keyboard presses, button presses, mouse moves, etc) and I'm also aware that the same event handling structure can be used to handle external (non-GUI) events- like those generated by a digital edge on a DAQmx input. My question is whether the sam... 15 Aug 2008 10:59
