Field Documentation
uint32_t LL_GPIO_InitTypeDef::Pin
Specifies the GPIO pins to be configured. This parameter can be any value of
GPIO_LL_EC_PIN
uint32_t LL_GPIO_InitTypeDef::Mode
Specifies the operating mode for the selected pins. This parameter can be a value of
GPIO_LL_EC_MODE.GPIO HW configuration can be modified afterwards using
unitary function LL_GPIO_SetPinMode().
uint32_t LL_GPIO_InitTypeDef::Speed
Specifies the speed for the selected pins. This parameter can be a value of
GPIO_LL_EC_SPEED.GPIO HW configuration can be modified afterwards using
unitary function LL_GPIO_SetPinSpeed().
uint32_t LL_GPIO_InitTypeDef::OutputType
Specifies the operating output type for the selected pins. This parameter can be a
value of GPIO_LL_EC_OUTPUT.GPIO HW configuration can be modified afterwards
using unitary function LL_GPIO_SetPinOutputType().
uint32_t LL_GPIO_InitTypeDef::Pull
Specifies the operating Pull-up/Pull down for the selected pins. This parameter can be
a value of GPIO_LL_EC_PULL.GPIO HW configuration can be modified afterwards
using unitary function LL_GPIO_SetPinPull().
uint32_t LL_GPIO_InitTypeDef::Alternate
Specifies the Peripheral to be connected to the selected pins. This parameter can be a
value of GPIO_LL_EC_AF.GPIO HW configuration can be modified afterwards using
unitary function LL_GPIO_SetAFPin_0_7() and LL_GPIO_SetAFPin_8_15().
