If you want to change pinout, do this in your defines.h file with lines below and set your own settings:

//RS - Register select pin
#define HD44780_RS_PORT     GPIOB
#define HD44780_RS_PIN      GPIO_PIN_2
//E - Enable pin
#define HD44780_E_PORT      GPIOB
#define HD44780_E_PIN       GPIO_PIN_7
//D4 - Data 4 pin
#define HD44780_D4_PORT     GPIOC
#define HD44780_D4_PIN      GPIO_PIN_12
//D5 - Data 5 pin
