Connecting a repurposed LCD with 1 data pin

[MichalW]

I just unsoldered an LCD from an old broken drone controller.

I've got the following pins, and no idea how to connect them:
LED+
LED-
CS
WR
DATA
GRND
VDD

I managed to make the backlight light up by wiring the LED+ to a 5v battery through a resistor and then to ground - about as much electrical skills as I have .

I understand that GRND connects to ground and VDD to the power. I'm confused with the CS (Chip Select) pin, WR (Write) pin, and especially the 1 DATA pin, and how to send data to it.

I'm not sure if I need to further desolder something to access each data pin, or if there is even more than 1 data pin.

Please see the pictures attached of the LCD!

Is this a fixed character display like a calculator or a dot addressable type?
What were you hoping to display on the screen?

Unless you can find a datasheet for the display, (if one exists), then there is no hope of making it work.
The datasheet will tell what each pin is for and how to program the display.

Do not attempt to connect this to the RPi unless you know for sure what you are doing.
The RPi uses 3V3 logic level only...... 5V levels will destroy your RPi.

Your best bet is to look at the markings on the display (you've partially hidden one in the first picture, it ends in "H-8801") and try googling for that name. You may find a datasheet or someone who has wired it]]one up to a project. If you can find that and are still stuck then reply here with the information that you have found and people will see if they can help you.

Frankly I just want to see characters on screen !

I've looked for the datasheet - and I've taken the picture to show the full markings in the hopes someone can identify it Sadly - no luck yet...

might be a good idea to post the picture then !

Once upon a time you could get hold of LCD displays salvaged from old Nokia phones. This link http://binerry.de/post/25787954149/pcd8 ... spberry-pi describes making one work with the Raspberry Pi.

I have, though - it's the picture above! That's the full code "H-8801"!
