Update History

V1.0.4 / 29-April-2016

Main Changes

  • General updates to fix known defects and enhancements implementation.
  • HAL RCC
    • Add suffix U for defines equals to 0xFFFFFFFF (fix MISRA error 10.6)
    • Optimization of HAL_RCC_ClockConfig().
    • Replace aAPBAHBPrescTable by APBPrescTable and AHBPrescTable defined inside system_stm32f1xx.c.

    • EIE bit is reset at the end of the reception.
  • HAL DMA
    • Add macro __HAL_DMA_GET_COUNTER to get the number of remaining data units in the current channel.

      • GPIO_SPEED_HIGH to GPIO_SPEED_FREQ_HIGH
      • aliases are created to keep backward compatibility
    • Reduce the default timeout value for the startup of the HSE form 5s to 100ms.

    • HAL_ADC_PollForEvent returns HAL_TIMEOUT if a timeout occurs instead of HAL_ERROR.
    • Trigger the assert_param of  the number of discontinuous conversion only if the discontinuous mode is enabled.
    • Enhance the check for ScanConvMode in HAL_ADC_Init.
  • HAL CAN
    • Clear the ERRI bit in HAL_CAN_IRQHandler.
  • HAL CORTEX
    • Remove the macro __HAL_CORTEX_SYSTICKCLK_CONFIG as duplicated by HAL_SYSTICK_CLKSourceConfig.
      • Create an alias to HAL_SYSTICK_CLKSourceConfig for backward compatibility.
  • HAL FLASH
    • The parameter ReturnValue of HAL_FLASH_EndOfOperationCallback, in the case of Pages Erase, now take the value of 0xFFFFFFFF if all the selected pages have been erased.
    • Add a new interface HAL_FLASHEx_OBGetUserData to get the option byte user data.
  • HAL GPIO
    • Remove a useless assert_param on the pull mode in HAL_GPIO_Init.
  • HAL I2C
    • Correct issue at reception of 2 bytes using memory polling and IT interface.
    • Correct a wrong management of the AF flag.
  • HAL RCC
    • Reduce the timeout of HSI, LSI and PLL to be closer to HW specifications:
      • HSI_TIMEOUT_VALUE reduced from 100ms to 2ms
      • LSI_TIMEOUT_VALUE reduced from 100ms to 2ms
      • PLL_TIMEOUT_VALUE reduced from 100ms to 2ms
  • HAL SD
    • Correct wrong calculation of the capacity for High Capacity cards.
  • HAL SPI
    • Remove incorrect reset of DMA parameter in HAL_SPI_Receive_DMA and HAL_SPI_Transmit_DMA.
  • HAL TIM
    • Remove useless assert_param.
    • Rewrite the assert_param when setting clock source.
  • HAL UART
    • Manage the case of reception of a character while the driver is not expecting one. This was causing a crash of the driver.
  • LL USB
    • Remove the NoVbusSensing feature from driver. (feature not present on STM32F1xx)

V1.0.1 / 31-July-2015

Main Changes

  • General updates to fix known defects and enhancements implementation.
  • HAL generic
    • stm32f1xx_hal_def.h
      • Update NULL definition to fix C++ compilation issue.
  • HAL ADC
    • Optimization of macro __HAL_ADC_CLEAR_FLAG.
    • ADC poll for conversion now return error status in case of ADC-DMA mode.
    • ADC polling functions now return HAL_TIMEOUT (or HAL_ERROR in case of configuration error).

    • Improving the ADC state machine.
  • HAL CAN
    • Field Data of CanRxMsgTypeDef and CanTxMsgTypeDef is changed from uint32_t to uint8_t.

    • Correct an issue making impossible to set Flash read protection level1 and  level2.
    • The activation of backup domain in RCC is systematic.
  • HAL I2C
    • Correct an issue depending of APB/I2C frequency which was preventing the STOP bit to be cleared.
      • The POS bit is now cleared at the beginning of each I2C API.
      • The POS bit is no more cleared near STOP generation.
  • HAL I2S
    • HAL_I2S_Transmit() API is updated to keep the check on busy flag only for the slave.

    • Update of HAL_RCC_OscConfig functionto correctly check LSEState.
    • Rework __HAL_RCC_LSE_CONFIG macro to manage correctly LSE_Bypass.
    • New HAL RCC macro to configure the SYSCLK clock source: __HAL_RCC_SYSCLK_CONFIG(__RCC_SYSCLKSOURCE__).

    • For some RPN, the prediv source management in HAL_RCC_OscConfig function was not used.
  • HAL RTC
    • CMSIS mask definition used instead of hardcoded values.
  • HAL SMARTCARD
    • Improve documentation
  • HAL TIM
    • All STM32F101xx and STM32F102xx defines were missing in the file stm32f1xx_hal_tim_ex.h.

  • HAL USB
    • Correct issue preventing USB Device double-buffering mode for IN endpoints to correctly behave.
    • Correct a bad configuration of Turnaround Time.
    • Correct USB_FlushTxFifo function which was leading to a GRSTCTL register corruption.
