Epe pic magnetometer

[Omerta 1312]

Good evening everyone, I made the EPE magnetometer but when I pass the hex file to pic16f877-20 then on my screen it shows a bar only on top with some lines. Why does not the file pass? If you have made it let me help, thank you

Sure no problem. Do you have my address?

Thank you very much... Yes, you sent me the address previously.

Hello Mr. Simons. It's been a long time, and I've tried a lot this long to find out the cause of the problem. But I didn't succeed, The reading is always changing. Can I send you please the sensors and the electronic card to find out the cause of the problem? Thank you.

hi

dear friends

In Iran, I do not have access to the FGM sensor

Can anyone help me make something like that?

regards

But can be a variation of 10 Hz is quite normal, compared to 50000Hz! no ?! even we can not notice this variation on an oscilloscope that displays one or two periods.

Hmmm that is very strange.
And yes first of all is power supply. But if you use LM78l05 this must be OK. You can use single LM78l05 for sensor and other for digital. Also mag-shield is made like this. So I really don't have idea. If I have board in my lab it is simple to find out.

Where is the problem ?!
The common thing between all these experiences is the power ... still same source of 5v ... I will then look at the power supply of 5v.

What power supply are you using??

For very sensitive circuits I always use a current limited Battery that is isolated completely from the AC Mains.

I have a note that I haven't mentioned before ... When I connect a single sensor, whether it is up or down, the lcd displays the same reading for T and B which is supposed to display a single reading next to T or B and the other must be 0

I'm going today to a technician who repairs the video camera, he has an oscilloscope. I then test one of these two sensors ... and the surprising thing that he has output a signal very stable and strictly square! it's really confusing !! So where's the problem ! I tested another project with arduino that uses the same sensors (mag-shield) and also the reading on the LCD is unsatble (still unstable reading from 1hz to 100hz). Where is the problem ?!

OK no problem. Send me only sensors. Address will be send under PM

Ok. I will send you the two sensors during this week. Thank you.

[amitech1982]

I can't send the device, I'm afraid that it will be reserved in the customs. And I'm sure that the device does not have problems.

Hi
Can you send me sensors back (address in on box), so I will check it and resend you back new one. You can also send me logger so I can check all.

Thank you. what is your address to send you the sensors.
