Use LCD data pins for other things

Greetings,

I'm new to C++, but I'm quite familiar with BASIC, so my question is this... With BASIC, and with a parallel LCD, I could use the data lines that feed data to the LCD for other things, when the LCD is not selected, which is most of the time.

Does this: #include LiquidCrystal.h make the data pins that feed data to the LCD unavailable for other uses?

Thanks,
Rich

Yes.

I don't believe that you could use those pins for other purposes just because you were programming in Basic.

Sure, if the LCD has a strobe input. But what about the traffic that the other devices see when the LCD is active?

I 'guess' one can disable those other devices as well :wink:
