#define TP_CS 6

#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]
in this example we use the following pin config for 16-bit GPIO interfacing:
GPIOB 8-15
GPIOC 4-7
GPIOE 0-3
