Re: more data acquisition drivers ?

Also...

See this thread: http://www.dsprobotics.com/support/viewtopic.php?f=4&t=75177

It has some of the modules I use for noise reduction.

Additionally, (for example) you can get the change of signal amplitude (subtract last sample from previous), and use that data to make a ...

Re: How to connect 2 computers digitally w. Flowstone?

Hi,

I was hoping someone may have done this before in Audio with the "Audio Stream In Module".

Check out this module, it can capture Audio from a remote location, then your second machine can process and play it.

I have done this with Video. I get an image from a Webcam, scale it ...

Re: more data acquisition drivers ?

Hi,

If any products connect as HID devices (most do) AND you can get the data format (usually found in the product SDK/API, and programming examples), you can use the FlowStone HID Module to do the data decoding. It works quite well. The built in modules do exactly that as far as I can tell ...

Re: Getting pixel color from bitmap with Ruby

See this (my) post: http://www.dsprobotics.com/support/viewtopic.php?f=2&t=14697

Still no real way that I have found, but I am no RUBY expert, that's for sure :lol:

Trog has some REALLY good info in the post though! :ugeek:

Re: Get Object Location

Yes of course,

You can even create (in Ruby) a rectangle to put the text in - I.E. "v.drawString @label,font,sf,rect,(Brush.new @color)", but again you can't seem to get at the LOCATION of that text in the MGUI...?

Again the idea here, is getting to the position data of the object of each item in ...

Re: Get Object Location

P.S.

You can see that information during and while positioning objects... the trick is how do I get at it?
In this example "Label wOptions v1 (5,5) sqr" is shown, and is the upper left corner of the insert point.

Get Object Location

Hi,

I need to find the location of an object inside a view, that I place somewhere in that view.

The example here, shows the text (label) location in the view, but how do I get that location point out of the view?

Also... can I get back any objects location?

The end goal for now, is to be able ...

Re: DAQ (LabJack) analog input voltage flickering/noise

Hi,

The way you are doing you filtering seems fine... For any of my ADC Systems I try and make the signal input / ADC capture as noise free as possible. But sometimes you still need some filtering.

Here are a few things I use (I grabbed them from a few schematics using ADC / Data Acquisition ...

Re: DAQ (LabJack) analog input voltage flickering/noise

Hi,

I design and build Data Acquisition Systems (since 1980 ), and have used LabJack, and others before, including my own PIC based microcontrollers over USB to FlowStone.

It looks like the LabJack "engine" has some digital filtering, and typically FlowStone runs communications as fast as possible ...
