I ask for help, does anyone have the eagle scematic format in eagle version, please help,

[liekwang]

IDX Pro is in a schematic eagle version

IDX PRO LED VDI

Hello friends
I ran P12F683 led vdi for testing.
led gives late information.
Is it possible to edit?

Not really.
The PIC is not a fast processor and there is a bit of math going on to determine metal type.
Same with the other VDI PIC displays (I run the Graphics version).
In field use it is the audio beep that one listens for to know there is a target. Then wave the coil back and forth across the target to get a VDI. The beep is used to 'pin point' target location not the VDI.

thank you WaltR,

VDI doesn't matter.
I need explanatory diagram and information to add C-scope 1220 audio vco.
i need your support in this regard.
Is there a PCB floor file with potentiometer for the front panel in the picture?
Best regards

Hello
Please please tell me how to set the coils.

version 1.x is not very usable, you could try version 2.0 instead: https://www.geotech1.com/forums/show...449#post269449, the pcb can be updated easily with the schematics, but you would need an additional led to indicate that MCP602 is in saturation and a MCP1525 that gives a precise adc offset of 2.5V, otherwise you might need to edit and recompile the source code to manually adjust your offset e.g. 2.49V that could trigger more noise if if has a different value and/or to tune other parameters that are hard-coded and cannot be changed in the running firmware...

I ask God why the threshold is not like a metal detector whites the sound treshold. Sound tresh on IDX has a lot of functions

[liekwang]

like the sound of idx is more interesting if you use the voice of cscope 1220B. has anyone tried it please share it

Hello friends. I am looking for the .hex for the Geotech VDI that has the contrast control included. Does anyone know where I can find it?

Hi
cscope 1220B robust scheme?

Hi
cscope 1220B robust scheme?

I'm also waiting for someone to do good to design a 1220B audio scope scheme to be installed on IDX

Hi
If there is an audio circuit diagram.
i test
Printed circuit drawing.
I do.
