Arduino based VDI!

[useus]

I don't understand, on idx pro, x and y must be connected to pins 1-14 or 7-8 of lf347?
I follow the scheme with mcp602 to build the vdi?


thanks!

Dear all
Im mad this vdi and connect to admiral metal detector put when i run device writ on the screen 93 dollar it musr nor writ any thing when start , i connect x,r to the ic 339 oin 2, 14
And try ic 347 pin 7,8 the same problems

Which admiral schematic? post the schematic.

This one i used

I attached the schematic in the last post

[dbanner]

Ok, I'll have a look to see where the VDI is attached

On the admiral schematic, it looks like pin 1 and pin 7 of U4 (TL062).

There is no LF347 so I assume this chip if from the idx schematic.

Thank you , i connect to pin 1and7of tl 062 and when i conect groun of arduino to the ground of admiral always give id 93 when any thing goes in the coil the id chang and return back to 93 fastly and whith out connect groun of arduino to ground of admiral give 0 value whithout any chang of id

I think problem is power supply. Look at page 9, post #212, where it is mentioned to use separate batteries for the Arduino.

These MD circuits use analog ground or "virtual ground".
So maybe do not connect the grounds of Arduino to MD circuit.

I give arduino power from laptob usb

Here is my new Arduino vdi project with small 128x64 display. Implemented bargraph and custom font's. Machine on the photo is IDX with 12.5 inch coil. Soon i will upload short video...

My friend is giving the library error while loading this code. Can you give the link to the library

[sdowman]

So it gives an error when uploading to arduino

All needed library's should be downloaded from GitHub site, i can only imagine which one code is giving error without the image. Post your error code or give picture about compile error...
