PureBasic Forums - English

Hello.
Once upon a time I was looking for a simple oscilloscope and today I managed to find something and came across your project.
I was looking for this meter to his small PV power plant built optimize yourself.
I want to do search and control point MPP.

I found such a product, which after a slight modification to met my expectations and maybe also other stakeholders.

To do this I have to add this project to the graphic and the button (L * R) - power (I * U = P).
And I wanted to make a record every 30 seconds and every 60 seconds to a file CSV or TXT.
Then I would do the calculations in MS EXCEL.
MPP for the optimal point of measurement for a long time.

Recording wanted me to take place without limitation of time, eg 1 week - 168 hours and more.
The save file to be following column numeric values:
date, time, L, R, L * R,

With the knowledge of the oscilloscope I found the choice too easy to modify.
But it might have been simpler to perform three meter with digital display:
1 - Voltage ranges 0-10V, 0-100V, 0-500V (left channel)
2 - Current ranges 0-1A, 0-5A, 0-10. (Right channel)
3 - Power - calculation (V * A) Wat.
I write to a file every 30 seconds or 60 seconds of the CSV or TXT data:
Date, time, V, A, Wat

Recording time up eg 1 week - 168 hours and more for then analyze the results using MS EXCEL.

Input signals to the measurements to the SOUND CARD stereo in with a circuit current and voltage dividers.

I do not know how to program'm just a retired electronics.

I look forward to help in this area.

Sorry for my bad English

Hi,

sounds like a nice project with both electronics and software involved.

I do not know how to program'm just a retired electronics.
I look forward to help in this area.

Sadly I do not get the point what kind of help you need and what the specific question is

Hello Kukulkan.
Thank you for your answer.


Acquainted with the project Oscilloscope.

But there is no possibility of recording the measured values to the file and it would was required to perform power calculations in MS EXCEL ..
A further link to pages placed to show what you want to calculate. But this is to be done with a large amount of measurement data and then ustwic optimal load point of PV panels on my house.

I found another project and this seems to me easier to change to fulfill what he wants to measure using the card for music input.

Slowly I begin to understand programming language in purebasic.
But I'm far from that I could modify programs tyk code written.
I think that this second project was to easier to adapt to my needs amateur.

Regards.
