To find the current ,watt and AVA in ade7880 using arduino uno

Is the run bit set in the RUN register? 

What is the state of the PSM0 and 1 pins? 

Dave

Thank you for your reply,

Run register(0xE228)  i did bit is set to 1.

and PSM0 is set to 1

PSM1 is set to 0 then only  normal mode is activate.

when i am reading the active power registers (0XE513,0XE514,0XE516) /(AWATT,BWATT,CWATT)  the raw data is same even i am giving the load through the PDU also.

FOR EXAMPLE: reading register is AWATT  value is 257 decimal. after that i am giving the load is 100 watt and 200 watt , but i am getting the raw data is same only.

What are you writing to the registers after power up? 

can you provide a schematic of your board and a connection diagram of your source and load? 

Dave

Thanks for your reply

when i am reading the current  register by the default its giving,

AWATT=16777215;

when i am giving the load like 100 watt 0r 200 watt ,the default value is decreasing like

100 watt =1677098

200 watt =16777012;

my doubt is when we are giving the load the default value must be increase  and also i given absolute functon also.

based on calibration value (constant->we can't change) only we need to get the watt.

and also

how to find the wthr, varthr, vathr  give any information  about this?
