This is a good question but unfortunately due to people who believe they know better, the answer is no. Too many people have come along, changed the program and made it impossible to tell which program works with any particular device.

The best thing for you to do is study the various methods for the operation of a PI unit and then design one yourself from the ground up.

thanks golddiger

the problem is i cant design pi detector,i can just build it.in this forum is a lot of circuit Smiley..can you suggest me  the  best one detector that can works with micro?? original hex file Tongue
i like to build a pi detector that it has Manuel and auto balance....can detect for example a coin in 30-40 cm in soil!!!!
so can you suggest me any circuit with this explain that write above??

again a lot appreciate

A good VLF could do that. Why do you want a PI with a micro?

i want pi because of it can detect object in depth..but a good vlf can detect max in 2 meter.
can you suggest any circuit...

No not one that can detect at 2m. The question was why do you want a PI with a pic micro processor?

1-see power of pulse in lcd
2-Stability can see better
3-if the circuit have Separation can ثeasy too see
4-work with micro is easier than analog
5-several menu is in micro for setting and filter
and the end..with manual balance and auto
sorry for my poor grammar  Smiley

Your grammar is not a problem. Here is what I think

1-see power of pulse in lcd (useless)

2-Stability can see better (Not true)

3-if the circuit have Separation can ثeasy too see (I don't understand)

4-work with micro is easier than analog (True there are less components)

5-several menu is in micro for setting and filter
and the end..with manual balance and auto (useless in my experience)

What size coil are you planing to use? I think that you want to find coins from what I understand from your previous post.  What I think you should do is build a simple PI detector and if you can build that with out any problems you should venture in a more advanced detector. I also think that with a simple PI detector you will find as much as with a more complex one but that's just my two cents worth to you. There are a lot of micro detectors out there to be build but like GD has already told you to many people did mods to them and no one really knows what schematic to use anymore.

All the best
Xavier

Xavier is giving you good advice. Build one machine first. A simple one. Then worry about a better machine later.

thanks zavier for reply
num 3, i mean separation from ferrous and non ferrous object can see better in lcd.. Wink
num2 , i like a circuit that after i build it when i work with it dont beep every time...stability a pi detector is important.

no,i like a pi detector that can detect objects in 4-5 meter depth...size of coil is 35 cm and 1*1 or 2*2...a circuit can work with these size coil... i am working with my friends to build a pro pi detector and simple circuit is not good for us..until now we build BRN , PIM2 , DELTA PULS... but we are not really satisfied from these pi...i hope now you understand that what i have to build???
again thanks
