Decoding LCD pins Data

Postby Rahul147 » February 11th, 2016, 6:24 am

Hi,
i have Digital orque adaptor.i just opened it i found their is Black-dot,their is LCD display which is having 16 pins.
now i want to transfer this LCd displayed data to 8051 microcontroller.
i want to know how can i do that?
i dont have detailed description of LCD which is mounted on that.
i am thinking to use cables and decode each signal from LCD pins and process it to microcontroller.
but i dont have oscilloscope inorder to read at each pins of LCD .
i dont know which pins of lCd signifies what..?
please help me out.
Can anyone help me out any alternate way by which i can decode the data from 16 pins of lCD and send to microcontroller?

It would be helpful to have a picture of the rear of the LCD display, showing any model number information.

Is this a text display? If so, how many lines of how many characters?

Driving an LCD directly w/only SW is difficult. You can easily destroy the LCD. It would be best to purchase an embedded processor with a HW LCD driver built in. There are plenty of these. Driving an LCD w/an Hitachi (like) interface is easy. The internet is flooded w/projects detailing how to use such a display. But it is impossible to tell which you have. That's why kww wanted a picture.
