LiquidCrystal_I2C_ByVac::LiquidCrystal_I2C_ByVac |
( |
uint8_t |
lcd_Addr | ) |
|
Class constructor. Initializes class variables and defines the I2C address of the LCD. The constructor does not initialize the LCD.
- Parameters
-
lcd_Addr[in] | I2C address of the IO expansion module. For BV4218, the address can be configured using the address commands (to be implemented). |
void LiquidCrystal_I2C_ByVac::begin |
( |
uint8_t |
cols, |
|

uint8_t |
rows, |
|
|
uint8_t |
charsize = LCD_5x8DOTS |
|
) |
| |
|
virtual |
LCD initialization and associated HW. Initializes the LCD to a given size (col, row). This methods initializes the LCD, therefore, it MUST be called prior to using any other method from this class or parent class.
The begin method can be overloaded if necessary to initialize any HW that is implemented by a library and can't be done during construction, here we use the Wire class.
- Parameters
-
cols[in] | the number of columns that the display has |
rows[in] | the number of rows that the display has |
charsize[in] | size of the characters of the LCD: LCD_5x8DOTS or LCD_5x10DOTS. |
Reimplemented from LCD.
void LiquidCrystal_I2C_ByVac::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_I2C_ByVac::setBacklight |
( |
uint8_t |
value | ) |
|
|
virtual |
Switch-on/off the LCD backlight. Switch-on/off the LCD backlight.
- Parameters
-
value | backlight mode (HIGH|LOW) |
Reimplemented from LCD.
void LiquidCrystal_I2C_ByVac::setContrast |
( |
uint8_t |
value | ) |
|
Switch-on/off the LCD contrast. Switch-on/off the LCD contrast.
- Parameters
-
value | contrast mode (HIGH|LOW) |
