Tool/software: Code Composer Studio

Dear All

I am trying to develop an 3 phase energy meter for one of our applications ,  i am using MSP490F67791A for the same ,  how ever i am unable to find the firmware or any other supporting libraries for the same can anybody share me the link for the same where i can get the library files so that i can start the development for the same

    Hello,

    I'm assuming that you're using the EVM430-F6779. There are several TI Designs based on this EVM. These include:

    • High Accuracy Three-Phase Electricity Meter with Tamper Detection (TIDM-THREEPHASEMETER-F6779)
    • Total Harmonic Distortion Measurement For Energy Monitoring Reference Design (TIDM-THDREADING)
    • Implementation of a 3-Phase Rogowski Coil Based Watt Hour Meter Reference Design (TIDM-3PHMETER-ROGOWSKI)

    On each of the TI Design product pages, there's a "Software" section where you can download the source code. You may be able to use links at the beginning of the User's Guides as well.

    Hi James

    Thanks for replying i downloaded the same code which is IAR embedded work bench i would like to develop this product in CCS how ever i clearly went through the data sheet and app not SLAA577 i came across the formula to calculate the RMS voltage and RMS current i need to have a few clarity on the same formula in section 4.2.1.1 in which they have mentioned as

    vph(n) = Voltage sample at a sample instant n

    i dont understand this , is this an RAW ADC Result in hex

    i am starting from scratch for this project because it is for industrial application which has other parameters to be monitored and controlled

    At this point, metrology code is not supported in CCS. Please see the links in the thread below.

    Yes, Vph(n) represents a sample from a SD channel connected to a voltage channel. For the exact SD settings, you can find those by searching through the code/project.
