## Update History ### V1.9.0 / 25-August-2017 Main Changes Maintenance release. Remove support of Atollic TrueSTUDIO STM32 (TrueSTUDIO) toolchain. Align stm32f0xx_hal_conf.h with latest template defined in HAL. Change assert_failed() prototype to be compliant with MISRA C rule 11.4 ### V1.8.0 / 07-April-2017 Main Changes Maintenance release Update stm32f0xx_hal_conf.h files : Compliancy with MISRA C 2004 rule 10.6 ('U' suffix applied to all constants of 'unsigned' type). Add definition of USE_SPI_CRC Update HAL_TimeBase_RTC_xxx examples to correct RTC_ASYNCH_PREDIV and RTC_SYNCH_PREDIV definition when LSI configured as RTC clock source. Update TIM_DMA, TIM_PWMOutput, SPI_FullDuplex_ComDMA, SPI_FullDuplex_ComIT, UART_TwoBoards_ComIT examples to be aligned with latest reference code. ### V1.7.0 / 04-November-2016 Main Changes Maintenance release. Change of HAL API for TIM : add AutoReloadPreload capability in TIM handler. Impacts in ADC, DAC, IWDG and TIM examples. Updated DMA_FLASHToRAM example to call HAL_DMA_RegisterCallback() function Updated WWDG examples to be in line with latest updates done on HAL WWDG drivers Remove the HAL_WWDG_Start and update the HAL_WWDG_Refresh functions in the main.c file Remove HAL_WWDG_MspDeInit function from stm32f4xx_hal_msp.c file Change of HAL API for IWDG : Removal of HAL_IWDG_Start function in the main.c of IWDG example. Update of HAL_TimeBase_TIM example to use TIM HW as time base source instead of Systick Add 2 new examples HAL_TimeBase_RTC_ALARM and HAL_TimeBase_RTC_WKUP Updated I2C examples to manage error case during data transfer (I2C_TwoBoards_AdvComIT, I2C_TwoBoards_ComDMA, I2C_TwoBoards_ComIT, I2C_TwoBoards_ComPolling) ### V1.6.0 / 27-May-2016 Main Changes Maintenance release. Updated system_stm32f0xx.c files: Added APBPrescTable definition. Updated I2C examples after I2C driver rework: I2C_TwoBoards_AdvComIT I2C_TwoBoards_ComDMA I2C_TwoBoards_ComIT I2C_TwoBoards_ComPolling I2C_WakeUpFromStop ### V1.5.0 / 29-January-2016 Main Changes Maintenance release. Add support of System Workbench for STM32 (SW4STM32) toolchain. Updated GPIO Output Speed literals naming to ensure HAL full compatibility. Updated FLASH_WriteProtection examples with new FLASH APIs. Updated TIM examples: Corrected calculation of uint32_t in TIM_InputCapture example. Update SystemClockConfig() for STM32F0xx-Nucleo examples. Updated/aligned UART_TwoBoards_ComDMA examples (UART IRQ needs now to be enabled). Updated ADC/ADC_AnalogWatchdog example. Added CRC/CRC_Data_Reversing_16bit_CRC example to illustrate input/output data reversal features. Added CRC/CRC_Bytes_Stream_7bit_CRC example to illustrate the usage Input/Output options CRC calculation. Updated system_stm32f0xx.c files: Removed __IO or __I on constant table declaration. Added HSI48_VALUE definition. Updated stm32f0xx_hal_conf.h files: Set HSE_STARTUP_TIMEOUT value to 100ms instead of 5000ms Updated “Liberty” License with the new license “Ultimate Liberty”. ### V1.3.0 / 26-June-2015 Main Changes Update ADC/DMA/PWR examples projects. Fix known defects and several enhancements implementation. Complete HAL API alignment (renaming). ### V1.2.0 / 05-Dec-2014 Main Changes minor correction (compilation warning with HAL_SPI) ### V1.1.0 / 03-Oct-2014 Main Changes official release. minor correction (compilation warnings) Example porting on IAR, KEIL, TRUE STUDIO ### V1.1.0RC2 / 01-Aug-2014 Main Changes First release. ## License Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.
