good morning everyone!

How to connect a 16 x 2 direct LCD to the Arduino Mega.

In the diagram shown the connection is made to an expansion card and the pin "D" that goes on the RS of the LCD, I do not know

thank you very much

Connect it exactly as on diagrams - directly to the address bus lines (4 wires) and to signal (pin) and data (D pin).
Why do you think this is some "expansion"?

Just getting started!

My only project is the button panel of c172!

I also had problems getting the LCD panel working.  I tried several different pins and would never get anything to display.  I finally tried one of the 'analog' pins (A8) and it started working for me.  Make sure you have everything wired up correctly and it SHOULD work.

Good Luck!

Thanks for the tip!

I'll try that pine! Are you connecting directly to mega 2560 or using multiplex?

thank you

It's absolutely no difference what pin number to use for signal wire ("LCD control pin") !

And, you cannot use multiplexer for LCD! http://simvim.com/svc_lcd.html

Take care about correct power supply  and reliable wiring.

finally worked!

I also only managed using the pin (A8).

thank you very much!
