I have opened the PCB of an old device in order to use its LCD screen, the problem is that the pcb indicates no model ID or whatsoever. I was wondering if someone could give me a hint here of whether it is possible to control what the screen displays. What I do know about the LCD screen is that it has 28 pins, And I googled the LCD controller model number, it gave me a datasheet of "16-Bit Ultra-Low-Power Microcontroller, 8kB Flash, 256B RAM, Comparator, 96 segment LCD", but that does not help me with the pinout of the screen if I want to connect it to the arduino.
I'd be grateful if anyone could help me with this, thanks :)
