### Edit boardfiles:
add the following to your board.h file, matching to your pinconfig:
#define TP_PORT GPIOC
#define TP_IRQ 4
#define TP_CS 6
#define LCD_DATA_PORT_1 GPIOB
#define LCD_DATA_PORT_2 GPIOB
#define LCD_DATA_PORT_3 GPIOC
#define LCD_DATA_PORT_4 GPIOE
#define LCD_DATA_PORT_1_BASE 0
#define LCD_DATA_PORT_2_BASE 4
#define LCD_DATA_PORT_3_BASE 8
#define LCD_DATA_PORT_4_BASE 12
#define LCD_CMD_PORT GPIOD
#define LCD_CS 12
#define LCD_RS 13
#define LCD_WR 14
#define LCD_RD 15
in this example we use the following pin config for 16-bit GPIO interfacing:
GPIOB 8-15
GPIOC 4-7
GPIOE 0-3
### Edit Makefile:
include lcd.mk:
include $(CHIBIOS)/ext/lcd/lcd.mk

### Use
1. include header files wherever you need it.
2. select the controller type you want to use in glcdconf.h
