I have a standard 4 line 40 character LCD unit which has a two-inch ribbon cable that ends in a 16 pin socket of 2 rows of 8.
The data sheet has pinout charts showing that pin 1 is D7, pin 2 is D6, pin 13 is ground, 14 is +5, etc.
But looking at the end of the socket, which is pin 1? There are 4 possibilities, but I don't have a clue which is right.
There are no markings on the socket; it's just a generic ribbon cable with press-on connectors.
I've searched dozens of data sheets, and they all tell how to do everything you could ever want with this display, except how to identify the pins on the connector.
Can anyone help?
