) |
| |
|
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.

) |
| |
|
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. |
