TIDA-010243: TIDA-010243 allow to store raw voltage and current values for 3 phases?

Part Number: TIDA-010243
Other Parts Discussed in Thread: ADS131M08

hi expert,

Good day. 

In TIDA-010243, it has a lot of calculated parameters like we required, which i think its very useful. For raw data, can we confirm the ref design also can supoort storing the raw voltage and current ADC values for phase A, B and C.

In section 3.10.1 of the reference design guide. it mentioned: The raw data from ADS131M08 samples are signed intergers and any stray DC or offset value on these converters are removed usig a DC trackin filter. A separate DC estimate for all voltages and currents is obtained using the filter, voltage and current samples, respecitvely. This estimate is then subtracted from each voltage and current raw ADC sample. 

Does this means we can also store raw voltage  and current ADC valjues for pahse A, B,C?

Best Regards,

Felix

    HI Felix,

    This TI design is designed by solution team. We do not know the details how they achieve this application as MSP team.

    However, based on your description, I think you can look into their code and check where they handle the raw ADC data. That may give you some clue on whether the code is storing the raw ADC data.

    Best regards,

    Cash Hao
