I am just getting started with the Cortex (and C.)

I would like to access an entire GPIO port but cannot find a way to address the port(GPIOF.)  I see the HAL functions for addressing the bits but not the entire port.Here is the code and error message:  const uint16_t MotorDriveStateTable[8]={0x0040,0x0060,0x0020,0x00A0,0x0080,0x0090,0x0010,0x0050};    uint16_t MotorDriveStateCount;    /* Infinite loop */  while (1)  {    /*EXPERIMENTAL CODE  */          HAL_GPIO_TogglePin(GPIOF, GPIO_PIN_4);(error)      *GPIOF &= 0x0ff0f;(error)      *GPIOF |= MotorDriveStateTable[MotorDriveStateCount];      MotorDriveStateCount++;      }/*end while (1) */-Error[Pe031]: expression must have integral type Would any one  be willing to help?

GPIOF->ODR &= 0x0ff0f;

GPIOF->ODR |= MotorDriveStateTable[MotorDriveStateCount];

Thank you for the lesson Clive.

I, finally, found the port definitions in stm32f051x8.h./**  * @brief General Purpose I/O  */typedef struct{  __IO uint32_t MODER;        /*!< GPIO port mode register,                                  Address offset: 0x00 */  __IO uint16_t OTYPER;       /*!< GPIO port output type register,                           Address offset: 0x04 */  uint16_t RESERVED0;         /*!< Reserved,                                                                 0x06 */  __IO uint32_t OSPEEDR;      /*!< GPIO port output speed register,                          Address offset: 0x08 */  __IO uint32_t PUPDR;        /*!< GPIO port pull-up/pull-down register,                     Address offset: 0x0C */  __IO uint16_t IDR;          /*!< GPIO port input data register,                            Address offset: 0x10 */  uint16_t RESERVED1;         /*!< Reserved,                                                                 0x12 */  __IO uint16_t ODR;          /*!< GPIO port output data register,                           Address offset: 0x14 */  uint16_t RESERVED2;         /*!< Reserved,                                                                 0x16 */  __IO uint16_t BSRRL;        /*!< GPIO port bit set/reset low register,   Address offset: 0x18 */  __IO uint16_t BSRRH;        /*!< GPIO port bit set/reset high register, Address offset: 0x1A */  __IO uint32_t LCKR;         /*!< GPIO port configuration lock register,                    Address offset: 0x1C */  __IO uint32_t AFR[2];       /*!< GPIO alternate function low register,                Address offset: 0x20-0x24 */  __IO uint16_t BRR;          /*!< GPIO bit reset register,                                  Address offset: 0x28 */  uint16_t RESERVED3;         /*!< Reserved,                                                                 0x2A */}GPIO_TypeDef;and then:#define GPIOF               ((GPIO_TypeDef *) GPIOF_BASE)
