Suppose I have 100 numbers of DSPs whose ADCs are converting analog data into digitals ones. The data may be current,voltage, frequency etc. Now DSP deals with counts only it does not understand engineering units like Volt, Amp, Hz etc. Now I want to display this "count" data in more engineering units on a single desktop. Remember I want to display the data of say 100 DSPs together on desktop. DSP has RS232 port for communication. How can I show scaled data from DSPs to single desktop? Which communication protocol/Interfacing softwware should I use?

For example : DSP 1--- I=16000 V= 500 F=1000 counts and scaling factor is 0-100 V equivalent to 0-32760 counts 0-10 A 0-32760 and 0-100 Hz equivalent to 0-32760 counts. How can i display on desktop?

Thank you for the information. Let me simplify my question. How can I transmit data from say 100 numbers of DSPs ADC via RS 232 protocol to a common desktop? I want to transmit the data from DSP to PC which will be pure counts and data will be converted into engineering units in desktop.No floating point operations will be done in DSP

  • \$\begingroup\$ you can use MATLAB (or OCTAVE, its free substitution) or as suggested in answer, LabVIEW. Each will have its advantage and disadvantage. \$\endgroup\$ – Mayank Jul 31 '17 at 11:31
  • \$\begingroup\$ How you display your data (especially what units you want to display) has absolutely nothing to do with the communication protocol or interface you are using. \$\endgroup\$ – Curd Jul 31 '17 at 14:47

If you have lots of different measurement devices and you are not a software developer you probably want to check out LabVIEW.

Throw the numbers into a text file and import them into python, excel, matlab or labview. Then graph and label.

You have to know the gain of your signal. If you have a voltage channel with a gain of 5 you need to account for that when graphing.

The first step is to convert your digital value to volts
Then find the total gain of the channel and divide the volts from the ADC.
Then graph counts vs voltage
