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 ???

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 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:

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
