EVM430-F6779: Energymeter building using MSP430F6779IPZ controller and different current sensor with (reference EVM430-F6779)

Tool/software:

Hello TI team,

We have builded the new model of energymeter using MSP430F6779IPZ controller and used different current sensor which gives 15 A and max 930mV.

In the energymeter EVM430F6779 you are using the current sensor which gives 65 A and 930mV.

I think because of difference in the current sensor change there should be a phase shift change right ? 

Also i want to know that how the current is calculated in the EVM430F6779 energymeter? I found out that it is stored in this register(0x0860). but dont know how its calculated and stored into this register?

#define SD24BMEM4_32_ (0x0860u)
#if !defined(__IAR_SYSTEMS_ICC__)
DEFL( SD24BMEM4_32 , SD24BMEM1_32_)
#else
__no_init union
{
DEFXC SD24BMEM4_8[4];
DEFXW SD24BMEM4_16[2];
DEFXL SD24BMEM4_32;
} @ (0x0860u);
#endif

I have already read this manual Implementation of a Three-Phase Electronic Watt-Hour Meter Using MSP430F677x(A) (Rev. G) multiple times.

Everything else works but the problem is in the measuring the current values. 

Where in the code i have to make the change such that i can get the current values similar to the reference energymeter EVM430-F6779.

Waiting for your reply.

Thank you.

Sincerely,

Abhi Panchal
