A-Star -- using the R/W pin on the LCD


#1

I have an A-Star 32U4 Prime SV (Pololu item #: 3115). I would like to use an LCD library by Peter Fleury. I see on the schematic that the R/W line is connected to ground through a resistor.

Peter Fleury’s library uses the busy flag on the LCD controller so R/W line needs to be connected. Can I just jumper the line to an input on the board for it to work (see picture below)? Or do I somehow need to remove the R/W line connection to ground as well?

Hello.

We do not expect any issues connecting R/W to an input on the A-Star like that.
