Pinbelegung des LCD Displays OPTREX DMC-40457

18 PIN INTERFACE
Used on the L40x4 (4x40)
Optrex - DMC-40457

On DMC-40457, signals on pins 17 & 18 are reversed.
E1 is the enable signal for the first HD44780 controller.
E2 is the enable signal for the second HD44780 controller.
VA is the LED backlight Anode.
VC is the LED backlight Cathode.
