This will use about 400 KB of extra space. - -## Configuration - -You will need to configure the pins used by your display and its number of lines and collumn in your keyboards `config.h`. - -Uncomment the section labled HD44780 and change the parameters as needed. -```` -/* - * HD44780 LCD Display Configuration - */ - -#define LCD_LINES 2 //< number of visible lines of the display -#define LCD_DISP_LENGTH 16 //< visibles characters per line of the display -#define LCD_IO_MODE 1 //< 0: memory mapped mode, 1: IO port mode -#if LCD_IO_MODE -#define LCD_PORT PORTB //< port for the LCD lines -#define LCD_DATA0_PORT LCD_PORT //< port for 4bit data bit 0 -#define LCD_DATA1_PORT LCD_PORT //< port for 4bit data bit 1 -#define LCD_DATA2_PORT LCD_PORT //< port for 4bit data bit 2 -#define LCD_DATA3_PORT LCD_PORT //< port for 4bit data bit 3 -#define LCD_DATA0_PIN 4 //< pin for 4bit data bit 0 -#define LCD_DATA1_PIN 5 //< pin for 4bit data bit 1 -#define LCD_DATA2_PIN 6 //< pin for 4bit data bit 2 -#define LCD_DATA3_PIN 7 //< pin for 4bit data bit 3 -#define LCD_RS_PORT LCD_PORT //< port for RS line -#define LCD_RS_PIN 3 //< pin for RS line -#define LCD_RW_PORT LCD_PORT //< port for RW line -#define LCD_RW_PIN 2 //< pin for RW line -#define LCD_E_PORT LCD_PORT //< port for Enable line -#define LCD_E_PIN 1 //< pin for Enable line -#endif -```` - -Should you need to configure other properties you can copy them from `quantum/hd44780.h` and set them in your `config.h` - -## Usage - -To initialize your display call lcd_init() with one of these parameters: -```` -LCD_DISP_OFF : display off -LCD_DISP_ON : display on, cursor off -LCD_DISP_ON_CURSOR : display on, cursor on -LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing -```` -This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`. -It is advised to clear the display before use. -To do so call `lcd_clrsrc()`. - -To now print something to your Display you first call `lcd_gotoxy(column, line)`. To go to the start of the first line you would call `lcd_gotoxy(0, 0)` and then print a string with `lcd_puts("example string")`. - -There are more posible methods to control the display.
