How to read out the Freemaster TSA table from another MCU

[kigerzhang]

      I use  the "Kinetis KM3x_256 MCU Three-Phase Metering Reference Design"  as metering  part of my 3-Ph power protect module.  That embedded the Freemaster  by using the SCI driver.   That can  easily be calibrated and turned by the Freemaster PC program .

      But  In my system the parameters need to be read out by another MCU (Keaz64) .   In order to simplify the interface  the Keaz64 will  use the same ISO UART to read the parameters .

   I read through  the  KM3x_256 code ,but not found the clear   scheme to read the TSA tabe . 

  Could anyone provide an  example   to demo the communication of the Freemaster PC with the board  ?

Or any  document  to indicate the communication protocol ?

Dear Alice,

Thanks for your reply.

My design is based on  DRM162.    What I want to do is reading  out the meter parameters  just like the Freemaster (Runing on PC)  is doing .

So I can totally re-use the DRM162 software . I can use the Freemaster to calibrate the meter , and  also I can use the same isolated UART to read out the  current and voltage sample data by Keaz64. 

I need the protocol that defines  how the Freemaster  communicate with the board.

Hi Kiger,

Sorry there isn't the describe about Freemaster protocol, only have the User Guide

under Freemaster install directory .

Dear Alice , 

Thank you ! 

You throw a light on me .  I found the new protocol version in the  Freemaster install folder .

Dear Alice,Alice_Yang‌

Now I find the AN2471 , that is exactly what I need .  But the version is old  which was published  in 2003  and missing the TSA .

Do you find an updated version?
