## STM32F4xx Standard Peripherals Library Drivers update History

### V1.0.2 / 05-March-2012

Main Changes

- All source files: license disclaimer text update and add link to the License file on ST Internet.
- stm32f4xx_dcmi.c

- DCMI_GetFlagStatus() function: fix test condition on RISR register, use if (dcmireg == 0x00) instead of if (dcmireg == 0x01)

- stm32f4xx_pwr.c

- PWR_PVDLevelConfig() function: remove value of the voltage threshold corresponding to each PVD detection level, user should refer to the electrical characteristics of the STM32 device datasheet to have the correct value

### V1.0.1 / 28-December-2011

Main Changes

- All source files: update disclaimer to add reference to the new license agreement
- stm32f4xx_rtc.c:

- In “RTC_FLAGS_MASK” define: add RTC_FLAG_RECALPF and RTC_FLAG_SHPF
- RTC_DeInit() function: add reset of the following registers: SHIFTR, CALR, ALRMASSR and ALRMBSSR
- RTC_SetTime() and RTC_SetDate() functions: add test condition on BYPSHAD flag before to test RSF flag (when Bypass mode is enabled, the RSF bit is never set).

### V1.0.0 / 30-September-2011

Main Changes

- First official release for STM32F40x/41x devices
- stm32f4xx_rtc.c: remove useless code from RTC_GetDate() function
- stm32f4xx_rcc.c, stm32f4xx_spi.c, stm32f4xx_wwdg.c and stm32f4xx_syscfg.c: driver's comments update

### V1.0.0RC2 / 26-September-2011

Main Changes

- Official version (V1.0.0) Release Candidate1 for STM32F40x/STM32F41x devices
- stm32f4xx_usart.h/.c

- Update procedure to check on overrun error interrupt pending bit, defines for the following flag are added:

- USART_IT_ORE_RX: this flag is set if overrun error interrupt occurs and RXNEIE bit is set
- USART_IT_ORE_ER: this flag is set if overrun error interrupt occurs and EIE bit is set

- stm32f4xx_tim.c

- TIM_UpdateRequestConfig(): correct function header's comment
- TIM_ICInit(): add assert macros to test if the passed TIM parameter has channel 2, 3 or 4

- stm32f4xx_pwr.h/.c

- Rename PWR_FLAG_REGRDY constant to PWR_CSR_REGRDY
- Rename PWR_FLAG_VOSRDY constant to PWR_CSR_VOSRDY
- Rename PWR_HighPerformanceModeCmd(FunctionalState NewState) function to PWR_MainRegulatorModeConfig(uint32_t PWR_Regulator_Voltage)

- stm32f4xx_rcc.h/.c

- RCC_AHB1PeriphClockCmd(): add new constant RCC_AHB1Periph_CCMDATARAMEN as value for RCC_AHB1Periph parameter

- stm32f4xx_spi.h

- IS_I2S_EXT_PERIPH(): add check on I2S3ext peripheral

### V1.0.0RC1 / 25-August-2011

Main Changes

- Official version (V1.0.0) Release Candidate1 for STM32F4xx devices
