OLD LCD
Hello I would like to exchange my printer's display.
It was a Displaytech 204 installed
Now I heard a Stm7920 obstruct.
I do not know the pin assignment exactly can someone control how it has to be connected and the pins from the firmware
can someone help me, i would like to connect it like picture 3 does that work at all?
Do I need extra resistance? Three Risistors on my LCD
What I find strange that on the lcd board with 3 resistors on the left side? are not there
see Picture stm7920
