Cross threading

I have a very simple C# single form program that opens an accelerometer and attaches event handler. When the event happens I try to write to a text box that is part of the form, but I get a message saying: "System.InvalidOperationException: 'Cross-thread operation not valid: Control 'AccelX' ac...

IMU Specs - Kalman filter

Does the PhidgetSpatial Precision IMU (MOT0110_0) incorporate a Kalman filter in its spatial output calculations? If so is there the ability to tune the filter?

Re: Load Cell and Bridge Frequency Response

I had an old 1046_0 4 input bridge lying around so I hooked that up in place of the DAQ1500. While it does roll off at the "higher" frequencies, it was significantly less than the DAQ1500. Load Freq_________~1Hz______________5.3Hz DAQ1500___________240Nm_____________90Nm 1046______________...

Load Cell and Bridge Frequency Response

I am using a 500Kg load cell (3140_0) and a DAQ1500 bridge to measure a reciprocating bending load on a beam. I capture my data samples at 33Hz and accumulate a large number of these samples and then display and save the peak value from the large sample size. By sampling across a large number of cyc...

Re: Versatile Input Freq Counter and 5V Sensors

Looks like the PSU2000_0 provides switched 5V to a terminal block for $10 - it just takes up a VINT port. That should get me there easy enough.

Versatile Input Freq Counter and 5V Sensors

The old frequency counters (1054_0B) had 5V available to power a 5V sensor. The new frequency counter (DAQ1400_0) says it works with a 5V sensor but it looks like it only supplies 12 or 24V. What is the recommended method of interfacing this to a 5V sensor? Do I need to add a regulator or an externa...

Re: Peak detection

Thanks for the suggestions. Since the waveform I am trying to capture is constant frequency it looks like I can sample over a number of cycles at a non-harmonic sample rate and get quite close to the peak value that way.

Re: .NET Core and UWP support status

I am currently trying to implement the use of Phidgets in C# UWP application, but the Phidgets throw an exception every time I try to open them. Is there a way to get the phidgets to work in UWP?

Peak detection

I have an oscillating load on a load cell. I would like to be able to capture the peak load on the cell, but my sampling time is likely not fast enough compared to the period of the peak load. Is there a way to capture peak load in the hardware?
