TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI;

TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;

TIM_ICInitStructure.TIM_ICFilter = 0x0;

TIM_ICInit(TIM3, &TIM_ICInitStructure);

TIM_SelectInputTrigger(TIM3, TIM_TS_TI1FP1);

TIM_SelectSlaveMode(TIM3, TIM_SlaveMode_Reset);

/* TIM enable counter */

TIM_Cmd(TIM3, ENABLE);

In FWLib V2.0, the TIM_ICMode member of the TIM_ICInitTypeDef structure was removed:

TIM_ICInitStructure.TIM_Channel = TIM_Channel_1;

TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising;

TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI;

TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;

TIM_ICInitStructure.TIM_ICFilter = 0x0;

TIM_ICInit(TIM3, &TIM_ICInitStructure);

TIM_SelectInputTrigger(TIM3, TIM_TS_TI1FP1);

TIM_SelectSlaveMode(TIM3, TIM_SlaveMode_Reset);

/* TIM enable counter */

TIM_Cmd(TIM3, ENABLE);

PWM input capture configuration

Typical code for TIM PWM input capture configuration based on FWLib V1.0:

TIM_ICInitStructure.TIM_ICMode = TIM_ICMode_PWMI;

TIM_ICInitStructure.TIM_Channel = TIM_Channel_1;

TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising;

TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI;

TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;

TIM_ICInitStructure.TIM_ICFilter = 0x0;

TIM_ICInit(TIM2, &TIM_ICInitStructure);

TIM_SelectInputTrigger(TIM2, TIM_TS_TI1FP1);

TIM_SelectSlaveMode(TIM2, TIM_SlaveMode_Reset);

In FWLib V2.0, the TIM_ICMode member of the TIM_ICInitTypeDef structure was removed

and a new function, TIM_PWMIConfig, was added:

TIM_ICInitStructure.TIM_Channel = TIM_Channel_1;

TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising;

TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI;

TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1;

TIM_ICInitStructure.TIM_ICFilter = 0x0;

TIM_PWMIConfig(TIM2, &TIM_ICInitStructure);

TIM_SelectInputTrigger(TIM2, TIM_TS_TI1FP1);

TIM_SelectSlaveMode(TIM2, TIM_SlaveMode_Reset);

SPI

In FWLib V1.0, the stm32f10x_spi.c/stm32f10x_spi.h driver is used to cover the

functionality of the SPI1 and SPI2 peripherals. The function format in this driver is as

follows:

SPI_FunctionName(SPIx, param1, param2,...)

e.g.: SPI_ITConfig(SPI_TypeDef* SPIx, u8 SPI_IT, FunctionalState NewState)

protocol.

In high-density devices, the SPI2 and SPI3 interfaces give the flexibility to use either the SPI

dedicated bit for each protocol.

The following sections describes the update made on this driver.
