Reading of signal from sensor and measure RMS of quantity.

Other Parts Discussed in Thread: TMS320F28335

Good morning

Respected sir/madam,

                            I am doing project using TMS320F28335. But i am unaware of coding.So i switched to Embedded coder.Now i need do to small experiment.My experiment is to sense current from current sensor and i need to measure RMS of sensed current.i am using ADC block for this purpose.

 

so i connected like this in program.My doubt is that how i can see RMS value.Because i am running the generated code in CCS. But how can i see.And what is the way to see the output RMS value in display MATLAB.And what gain i need to adjust before  i am doing RMS calculation.I am very poor in these things.Please kindly help me.

Any suggestions could be help full for me ,

Thank you,

With Regards,

Praveen.

    Hi Praveen,

    Our support provides the ADC block that samples input voltage and provides equivalent digital counts. How to use these counts for subsequent measurements is specific to your application, so I cannot provide guidance on how to do this.
