## Member Function Documentation

void LiquidCrystal::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 | Value to send to the LCD.

Returns
  mode LOW - write to the LCD CGRAM, HIGH - write a command to the LCD.

Reimplemented from LCD.

void LiquidCrystal::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. For dimming control of the backlight, the configuration pin must be a PWM output pin. Dim control is achieved by passing a value from 1 to 255 as a parameter. If the pin configured when calling the setBacklightPin does not support PWM, then: (0) backlight off, (1..255) backlight on.

Parameters

  value | backlight value. 0: off, 1..255: dim control of the backlight. For negative logic 255: off, 254..0: dim control.

Reimplemented from LCD.

void LiquidCrystal::setBacklightPin | ( | uint8_t | pin,
|  | t_backlightPol | pol
| ) |  |

virtual

Sets the pin to control the backlight. Sets the pin in the device to control the backlight.

Parameters

  pin | pin assigned to the backlight
  pol | backlight pin control polarity (POSITIVE, NEGATIVE).
