Hello,

Is it possible to read from HD44780 LCD? Can someone please give me an example, if it is possible with Arduino UNO?

Best regards.

What does reading from a Keypad have to do with a LCD Controller?

@James C4S, this is an ordinary and cheap Sony tv remote controller. As it has 0 to 9 keys and some other keys, I am thinking to use this instead of regular keypad. With a sensor individual key press can be detected. So, if key 0 (to 9) is pressed can be detected and printed on LCD. After entering (if needed editing - like a key on remote can be used as backspace) the complete number, a 'Finish' key would be pressed and the final number would be read from the LCD. Perhaps, now I have to think about using an array and keep track on it, then print the array on the LCD.

@kowalski, it seems the project/library was not completed successfully. But this would help for understanding or writing library for LCD. Meanwhile, I shall try the array way.

Thank you all.

Best regards.
