## Constructor & Destructor Documentation

LiquidCrystal_SR3W::LiquidCrystal_SR3W | ( | uint8_t | data,
|  | uint8_t | clk,
|  | uint8_t | strobe
| ) |  |

Class constructor. Initializes class variables and defines the IO driving the shift register. The constructor does not initialize the LCD. Default configuration: Shift register LCD QA - 0 DB4 QB - 1 DB5 QC - 2 DB6 QD - 3 DB7 QE - 4 E QF - 5 QG - 6 Rs GND Rw

Parameters

  strobe[in] | digital IO connected to shiftregister strobe pin.
  data[in] | digital IO connected to the shiftregister data pin.
  clk[in] | digital IO connected to the shiftregister clock pin.

## Member Function Documentation

void LiquidCrystal_SR3W::send | ( | uint8_t | value,
|  | uint8_t | mode
| ) |  |

virtual

Send a particular value to the LCD. Sends a particular value to the LCD for writing to the LCD or as an LCD command.

Users should never call this method.

Parameters

  value[in] | Value to send to the LCD.
  mode[in] | DATA - write to the LCD CGRAM, COMMAND - write a command to the LCD.

Reimplemented from LCD.

void LiquidCrystal_SR3W::setBacklight | ( | uint8_t | value | ) |

virtual

Switch-on/off the LCD backlight. Switch-on/off the LCD backlight. The setBacklightPin has to be called before setting the backlight for this method to work.

See also
  setBacklightPin.

Parameters

  value | backlight mode (HIGH|LOW)

Reimplemented from LCD.

void LiquidCrystal_SR3W::setBacklightPin | ( | uint8_t | value,
|  | t_backlightPol | pol = `POSITIVE`
| ) |  |

virtual

Sets the pin to control the backlight. Sets the pin in the device to control the backlight. This device doesn't support dimming backlight capability.

Parameters

  value | pin mapped on the 74HC595N (0, .., 7) for (Qa0, .., Qh7) respectively.
  pol | polarity POSITIVE|NEGATIVE.
