Hello,
I bought a 4x40 LCD at Ebay,i think it is new.
I only know that is a M4024 Display with 2 KS0066(F00) controllers.(eventually manufactured by Seiko?)
My Ebay-Partner sent me a wiring schematic and the specifications,it looks like it is a part of this PDF-document:
http://www.glyn.de/New_home/Produkt...heets/Seiko_Instruments/SI_Manual Italien.PDF
I think i have done it correctly,but the display shows nothing.
Afraid from the feeling i have it broken i searched at google for websites about it.
I found a data sheet for a display like my one,but with other pinouts.
In the datasheet i got from Ebay are lcd-pin 1-8 D0-D7,in the other they are D7-D0.
The other connections are the same.
What´s the right pinout?
I wired it on the 1 th and by the 2nd way,but it still shows nothing.
The only effect i have watched is that the first of the 2 KS0066 controllers becomes a little bit warm.(not hot)
Why i can´t see anything?
It is a possible matter that i not connect a potentiometer between the +5V and the VLC-pin at the display?
Please help me!
(...sorry for my very bad english!)
