DC energy meter with ADE755 and PIC16F877

[astra91]

Hello I am working on a project to measure the DC energy with ADE7755 and PIC16F877 want to ask of Where can I find the C code for this peak to indicate if someone has an idea or some where is an example to help me I would be extremely grateful.

Have a look at this forums post.

I had seen such project published in Electronics for You Magazine, i will provide you link soon.

Hi,

The link is for AC energy meter.

Building a DC energy meter is much more simple.
Just measure current with a fixed sample rate.
Multiply it with the voltage (should be constant for a DC source). Then you have the Watts.
Divide it by the sample frequency (f in 1/s for Ws, f in 1/h) to get the energy per sample
Integrate this value to get the energy.
