### V1.0.1 / 18-June-2014 Main Changes HAL generic update Fix flag clear procedure: use atomic write operation "=" instead of ready-modify-write operation "|=" or "&=" Fix on Timeout management, Timeout value set to 0 passed to API automatically exits the function after checking the flag without any wait. Add new macro __HAL_RESET_HANDLE_STATE to reset a given handle state. HAL CEC update Process no more locked during the transmission in interrupt mode. HAL COMP update Add NonInvertingInput field in the COMP_InitTypeDef structure. Add new defines COMP_NONINVERTINGINPUT_IO1 and COMP_NONINVERTINGINPUT_DAC1SWITCHCLOSED HAL DMA update Fix in HAL_DMA_PollForTransfer() to set error code HAL_DMA_ERROR_TE in case of HAL_ERROR status HAL I2C update Add management of NACK event in Master transmitter mode and Slave transmitter/receiver modes (only in polling mode), in that case the current transfer is stopped. HAL I2S update I2S clock source change: new define I2S_CLOCK_SYSCLK, remove I2S_CLOCK_PLL Improvement done in I2S transfer/receive processes HAL IRDA update Add new enum typedef IRDA_ClockSourceTypeDef Add new macro __HAL_IRDA_GETCLOCKSOURCE Change in HAL_IRDA_Transmit_IT() to enable IRDA_IT_TXE instead of IRDA_IT_TC. Process no more locked during the transmission in interrupt mode. HAL PCD update Add new macro __HAL_USB_EXTI_GENERATE_SWIT HAL PWR update Fix in HAL_PWR_EnterSTANDBYMode() to not clear Wakeup flag (WUF), which need to be cleared at application level before to call this function HAL RCC update Add USB peripheral and clocking macros for STM32F078xx device. Fix HSI Calibration issue when selected as SYSCLK HAL SMARTCARD update Change in HAL_SMARTCARD_Transmit_IT() to enable SMARTCARD_IT_TXE instead of SMARTCARD_IT_TC. Process no more locked during the transmission in interrupt mode. HAL SMBUS update Fix Slave acknowledge issue: Slave should ack each bit and so stretch the line till the bit is not ack HAL TIM update Fix macro __HAL_TIM_PRESCALER HAL TSC update Fix define TSC_ACQ_MODE_SYNCHRO HAL UART update Change in HAL_LIN_Init() parameter BreakDetectLength to uint32_t Change in HAL_UART_Transmit_IT() to enable UART_IT_TXE instead of UART_IT_TC. Process no more locked during the transmission in interrupt mode. HAL USART update Change USART_InitTypeDef fields to uint32_t type Rename __USART_ENABLE and __USART_DISABLE macros to respectively __HAL_USART_ENABLE and __HAL_USART_DISABLE Change in HAL_USART_Transmit_IT() to enable USART_IT_TXE instead of USART_IT_TC. Process no more locked during the transmission in interrupt mode. Change in HAL_USART_TransmitReceive_DMA() to manage DMA half transfer mode ### V1.0.0 / 20-May-2014 Main Changes First official release of STM32F0xx HAL drivers for STM32F030x4/x6, STM32F030x8, STM32F031x4/x6, STM32F051x4/x6/x8, STM32F071x8/xB, STM32F042x4/x6, STM32F072x8/xB, STM32F038xx, STM32F048xx, STM32F058xx and STM32F078xx devices. ## 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.
