Re: [oopic] Re: NC2004A LCD Screen with Modtronix LCD2S daughter board

I'm going to ask about that! But even if .String had been left in I
know that the oI2C object in all of its wrappers always sent a single
byte, never a string of bytes with a single break. This has
traditionally created issues for I2C connected display devices.
