Matrix user forums

Hi All!

I think someone, once made ​​an example with a millivolt meter and think it was Enaul. I have searched the forum but can not find it. Is there anyone here who can remember it and possibly know where it is. Or do I remember wrong.

Thank´s in advance

Hi Rene!

Yes, yes. Thank´s

If you need better accuracy or lower mV reading have a look at this circuit:

It is easy to get it to work in Flowcode,I have some code if you are interested.

But if you choose this hardware it is important to have a vert clean 5V supply since any ripple or spikes will show in your measurements. I have added some extra filtering of the 5V supply to further increasethis. There are app notes from Microchip describing how to do this.
