Epe pic magnetometer

The problem is both in the programming of the PICs but also on the board (tracks and components).

The problems I described in my original post occured with a couple of pics programmed with Microchip Pickit3

However, when I reprogrammed the same couple of PIC's with Velleman K8076 programmer the results were better:
* with one of the pics, all installed eeproms are seen, and all functions are ok, but no data transfer is possible
* with the other pic, all functions plus data transfer are ok, but the resulting data files are "empty" (no data)

Regarding the board, I made only one modification: I put a 10K resistor between IC6 output and IC4 pin#1 (following shansov's tip after a post back in 2012)

Generally, I see that much of the instability of the kit was due to programming and the bahaviour of the kit depends on the programming device and software.

I will continue testing the kit and let everyone know about any other findings

Sorry for late replays. I'm not often on my computer....
Look very strange ALL programmators must do same job! There is something wrong on your side. Do you sure, that you have right fuses?

two software !
same sensor 200yt!
exactly the same targets 2 row and 5 impulse !

I have better resolution

Hello

have one Question about EPE pic magnetometer. In the partslist of EPE Mag is the Ic PIC16F877-20 as component listed. Can i also use PIC16F877-20P. What does the "P" stands for???

[SimonS]

P mean PDIP package. So this is what you need.

[Prospekteur]

Ok thanks a lot. It can be so easy..........;-)

scheme то fgm 3 simple magnetometer,Can you it publishes?
thank you

I want to make the scheme on Mr. ivconic

Hi, is there's a new version HEX file?

HiI have made this magnetometer. Can any one give a hint about " how to use Geosurveior software"?Is it possible to transfer the data from logger to this software directly?All the bestAli

[Orbit]

Of course you can !

[wtrk]

Of course you can !

How ?
Could you please explain it ?
