### 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 TP_PORT GPIOC
#define TP_IRQ 4
#define TP_CS 6
#define LCD_DATA_PORT GPIOE
#define LCD_CMD_PORT GPIOD
#define LCD_CS 12
#define LCD_RS 13
#define LCD_WR 14
#define LCD_RD 15
#define LCD_DATA_PORT_1 GPIOB
#define LCD_DATA_PORT_2 GPIOC
#define LCD_DATA_PORT_1_BASE 8
#define LCD_DATA_PORT_2_BASE 0
#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 GPIOC[0:7] for DB[0:7] and GPIOB[8:15] for DB[8:15]
### Edit Makefile:
include lcd.mk:
