I have been looking for a way to do Live Graphing of multiple temp outputs.

Using the FlowStone DAQ board, is there a way to do live graphing with
FlowStone and have a calibrated scale of 50 deg F to 600 deg F and have 4
different infrared temp probes display in different colors, polling every minute
and updating a graph as well as outputting a log file of the recording
session for later viewing in a spreadsheet/graphing application with a
temperature alarm for each probe set to go off at 500 deg F (or
adjustable)?

Yes this is all possible with FlowStone! The key is to use arrays to store the temp values. These can be displayed as live graphs and stored to disk as CSV text data which can be opened in a spread sheet etc.

Can someone provide examples of this working. Have attempted this without success.

Thanks,

There is a save CSV data log example here:

And an example of how to average a signal and display it on a graph:

Here you go, I took what 'Embedded' posted and sort of put it together for you!

You might need to play with the scales and the graph axis to get exactly what you want.

This program averages the temp reading over 1 min. then stores the average value in an array. When the array reaches 60 (ie. 1 hour) it dumps to data to disk as an CSV file. So every hour you get a new file (time stamped so that you can identify it). As it is a CSV you can open it directly in Excel.

Enjoy....

Embedded and DSP,

Thank you for your response.

The examples really help.

I had come to FlowStone and SynthMaker having heard about it being discussed in another community I belong to. The way FlowStone is presented, I believed it to be much easier than what I have experienced. These examples really help me understand how things work within FlowStone and SynthMaker. Without examples from both, I would really be lost.

I believe the FlowStone community will expand as more and more schematic examples are presented that include FlowStone, Phidgets and various sensors, etc hooked up in a particular schematic to show how all parts relate and working examples.

Thanks again,

GII
