Anyone know how to communicate with ADE7758 through SPI Protocol. I know SPI Protocol but the ADE7758 Communication registers are not working.

I have just also tried a long time.
Important is to set SCLK to low, after read is done.
Otherwise i got also nothing, because interface disables itself.
Its not written in manual und was hard to find...

Hi everyone,Im a student of Electrical Engineering Im trying to communicate the ADE7758 with a PIC18F4620 through SPI protocol, but it doesnt work, Im trying to read and write the ADE7758 communications registers but the ADE7758 send corrupted values, I dont kwnow what is going on here
best regards....

Hai im ECE student..im doing project with ADE7758..
Due it's high cost i need alternate ic for ADE7758..
so pls tell suitable alternate IC for ADE 7758.....

Hello,
I am using ADE7758 with PIC18f97j60 and the expected AWATTHR, BWATTHR and CWATTHR register values calculated as per the equation given in the calibration section using line cycle accumulation mode gives a huge difference with the value read from the same registers. Can any1 help me in calibrating the chip.

Hello
I want to use ADE7758, I'm a novice and I have built up an evaluation kit with Codemercs IO warrior.
Measuring voltage and current AIRMS and AVRMS works fine. However WFORM register is always zero, whatever I select in WAVMODE.

Another problem are the energy registers, AWATTHR.. Those values are undefined, I'm reading 100 ms cyclic with reset at reading (LCYCMODE==0xC8).
Thanks for a hint.

Hello, I have read in analog devices forum but I donĀ“t find anything about this, Anyone know how to communicate with ADE7763 through SPI Protocol?
I am programming with C.

Thank you so much

I wait your reply,

Hey people,

does someone know in what unit is active energy in registers AWATTHR, BWATTHR and CWATTHR? I can measure currents and voltages, but energies are showing me to small walues.
Is there some proper equations for it?

Thanks in advance,
Tomas.

I found it.

Active pover = AWATTHR * Vmax * Imax * 2^25 * 0.4Exp-6 /(0x19999A * 3600)
[Wh]
where Vmax/Imax is maximal voltage/current amplytude; 2^25 represents lost register bits; 0.4Exp-6 is one time step [s] and 0x19999A is maximal power increase by one step

Have fun,
Tomas.

I am unable to understand your post. Can you please elabrote the formulae to calculate ACTIVE POWER from AWATTHR.
