STM32F4 StdPeriph GPIO_MODE

[Beescloud]

i use nucleo-f446ze learning how to use STM32F4 stdperiph，but in STM32F4XX_GPIO.h，GPIO_MODE only have 4 mode，

GPIO_Mode_IN = 0x00, /*!< GPIO Input Mode */
GPIO_Mode_OUT = 0x01, /*!< GPIO Output Mode */
GPIO_Mode_AF = 0x02, /*!< GPIO Alternate function Mode */
GPIO_Mode_AN = 0x03 /*!< GPIO Analog Mode */

in STM32F10_GPIO.h，have 8 mode

GPIO_Mode_AIN = 0x0,

GPIO_Mode_IN_FLOATING = 0x04,

GPIO_Mode_IPD = 0x28,

GPIO_Mode_IPU = 0x48,

GPIO_Mode_Out_OD = 0x14,

GPIO_Mode_Out_PP = 0x10,

GPIO_Mode_AF_OD = 0x1C,

GPIO_Mode_AF_PP = 0x18

if i want to use PP in the STM32F4，i should use gpio_pupd？can explain why different design？ 

Best regards！

push-pull vs open-drain is specified in a different field. Use GPIO_OType_PP in the GPIO_OType field to specify push-pull.

}GPIO_InitTypeDef;

Unless you have a convincing argument, it would be more beneficial to use the HAL libraries rather than the old standard peripheral libraries, which will not be updated and do not support newer hardware.
