Function Documentation

lcd_clicked()

uint8_t lcd_clicked

(

void

)

Consume click event, following call would return 0. See #LCD_CLICKED macro for version not consuming the event.

Generally is used in modal dialogs.

Return values

0	not clicked
nonzero	clicked

lcd_print_pad_P()

uint8_t lcd_print_pad_P	(	const char *	s,
		uint8_t	len
	)

Parameters

s	string from PROGMEM.
len	maximum number of characters to print, including padding. Ranges from 0 to LCD_WIDTH.

Returns

number of padded bytes. 0 means there was no padding.

lcd_set_cursor_column()

void lcd_set_cursor_column

(

uint8_t

col

)

Parameters

col	column number, ranges from 0 to LCD_WIDTH - 1
