Detailed Description

In the Arduino environment, the LCD_I2C class constructor is different, as well as the setCursor function parameters. Here are the differences.

Function Documentation

◆ begin()

void LCD_I2C::begin ( )

inlinenoexcept

For Arduino, initialize the I2C bus and the display.

The I2C bus is initialized by calling Wire.begin(). Then the LCD display is placed in the correct initial state. begin() must be called before anything else is done.

◆ LCD_I2C()

LCD_I2C::LCD_I2C	(	uint8_t	lcd_addr,
		uint8_t	lcd_cols,
		uint8_t	lcd_rows,
		uint8_t	charsize = `LCD_5x8DOTS`
	)

noexcept

The ARDUINO Constructor.

Remember that constructor usage for ARDUINO and Pi Pico is quite different.

For ARDUINO: Create the object with the constructor and then call the begin() method. If you wish to change the bus speed, do it before calling begin().

Parameters

lcd_addr	I2C slave address of the LCD display. Most likely printed on the LCD circuit board, or look in the supplied LCD documentation.
lcd_cols	Number of columns your LCD display has.
lcd_rows	Number of rows (lines) your LCD display has.
charsize	The size in dots that the display has, use LCD_5x10DOTS or LCD_5x8DOTS. (5x8 is the default if charsize is omitted.)

◆ setCursor()

void LCD_I2C::setCursor	(	byte	position,
		byte	line,
		bool	Enable_Buffering = `false`
	)

noexcept

For Arduino, move the input cursor to a location on the screen.

All output to the screen is placed at the current cursor position. In the default mode, the cursor then advances one position to the right. The cursor does not scroll to the next line.
