[erdin]

Iv given up on mine cant get it to work

Jap,
I dont know the Ohms or Uh. I will take the coil to an electronics shop and have them tell me.
Then I will post here and let you know.


Thank you

Hi volcano
-OK ,,,
to get -E,+E,,,
--RE, IN PHOTO in reply#281 ,there Open its cotroll ON it come from the PIC -----> FOLLOW pdf to test +E=12v.

Hi DianaBlu
-U say,, all seem to work correctly. But the display works bad...HOW..???????

Hi jap
I changed the IRF9540 and IRF740, VD12, VD13,VD15
But I have already the same problem ( +E=2.1v)

please Help me

Hi all. I have just finished my hardware, waiting for the full hex. I have tried the demo, and all seem to work correctly. But the display works bad.


I have a GDM12864H, and i have read here that the H series doesn't work with the DP3.


I found two LCD:
12864A -> https://www.distrelec.it/ishop/Datas...-n_eng_tds.pdf
12864B -> https://www.distrelec.it/ishop/Datas...-n_eng_tds.pdf


Are they OK? What's the difference between the A/B and the H series?
Thank you
Max

Hi eaglewings35
-is inner coil ohm, uh ok?
-DP3 has the sensitivity to coil ohm, uh----if not---> u gite (error connect the coil) on lcd!!!
-for Whites TDI (PI) coil see link:

PI Coil question

Hi eaglewings35
because two coil must The match in the specifications ohm , uh.
-So you are using 2 coil do not match so it must control every time when you change the coil.

HI JAP, The coil I have is a Whites TDI (PI) coil. It is a double coil, which I understand will not work.
My question is this.....

If I cut (disconnect and take out) the inner coil, making it a mono coil, would it then work?
The coil would then only have 1 coil, not 2.

Make sense?

Hi Jap
I test +E, I find it =2.1V
I think that the IRF9540 is damaged

[volcano]

thank you Jap

We have the wedding of my brother in these days
I see you next week..... ok

thanks

Hi volcano
-VD13=1N4007....OK

Hi Jap
I adj TR1 Many times but no result ( the line always remains horizontal ).
I inform you that I used (VD13=1N4007) because I did not find 1N4001
What is your opinion ???

[jap]

I got a best result, I had a single problem ( the pic can not detect the coil).



I mesure the +12,-12,+5, and +E =+2.1v
But I did not mesured the -E ( because I do not know the value of +E and -E)

thanks

Hi volcano
+E=+12V , -E=-10.6V
- can not detect the coil , u need to adj TR1.

Hi Jap
when I finished the project
I got a best result, I had a single problem ( the pic can not detect the coil).

but now I have this big problem

I had changed the 3 diodes.
before I change the 3 diodes , i test it , all are well.

I mesure the +12,-12,+5, and +E =+2.1v
But I did not mesured the -E ( because I do not know the value of +E and -E)

thanks

Hi volcano
-changed the 3 diodes to will have -E,TEST+E,,,
-Follow from start pdf to test step by step to find the error,,,
- is the LCD light---> if OK---> GO TO PIC +( different JDM programmer to be sure from), test each pic in read only--->its a sign its true .
-LCD light--->its a sign the pcb good.
-Delta is Delta, is considered deeper as he accepts the development ,It is development to improve the performance of that every developer has the direction of the development.So each and every one of them will be better if you get a good coil and good components and followed the instructions carefully you will get good results and be better Delta --- As ( PIM-2 , DP3 ).
-I do two , two as the same.
- take your time to do.
