Detailed Description

Writes data to the LCD on the 3pi+ 32U4.

This library is similar to the Arduino LiquidCrystal library, but it has some extra features needed on the 3pi+ 32U4:

• This class disables USB interrupts temporarily while writing to the LCD so that the USB interrupts will not change the RXLED and TXLED pins, which double as LCD data lines.
• This class restores the RS, DB4, DB5, DB6, and DB7 pins to their previous states when it is done using them so that those pins can also be used for other purposes such as controlling LEDs.

This class inherits from the Arduino Print class, so you can call the print() function on it with a variety of arguments. See the Arduino print() documentation for more information.

For detailed information about HD44780 LCD interface, including what characters can be displayed, see the HD44780 datasheet.

Member Function Documentation

noAutoDisplay()

void Pololu3piPlus32U4::LCD::noAutoDisplay ( )

inline

This does nothing, but it is here for compatibility with the OLED class. It lets us write examples that work with either class.
