Release Notes for STM32L0xx CMSIS

Copyright 2016 STMicroelectronics

 

Update History

V1.7.2 / 25-August-2017

Main Changes
  • Removed DATE and VERSION fields from header files.

V1.7.1 / 25-November-2016

Main Changes
  • Updated IS_COMP_COMMON_INSTANCE() macro.
  • Corrected ADC_CFGR2_TOVS bit and mask definitions.

V1.7.0 / 31-May-2016

Main Changes
  • Added Pos and Msk macros missing within the CMSIS stm32l083xx.h file.
  • Added LCD_CR_BUFEN bit definition in LCD CR register for stm32l053xx, stm32l063xx, stm32l073xx, stm32l083xx devices.

V1.6.0 / 15-April-2016

Main Changes
  • Add Pos and Msk macros within the CMSIS files. 
    • For example, on the previous CMSIS version (V1.5.0), the constant ADC_IER_EOCALIE was defined as follow :
      #define ADC_IER_EOCALIE                     ((uint32_t)0x00000800U)
    •  On this new CMSIS version (V1.6.0), the constant ADC_IER_EOCALIE is now defined as follow :
      #define ADC_IER_EOCALIE_Pos               (11U)
      #define ADC_IER_EOCALIE_Msk              (0x1U << ADC_IER_EOCALIE_Pos) 
      #define ADC_IER_EOCALIE                      ADC_IER_EOCALIE_Msk
    • The same rule applies on all the other constants present inside the CMSIS files.
         

  • MISRA C 2004 rule 10.6 compliancy. (A 'U' suffix shall be applied to all constants of unisgned type).

  • Several SYSCFG definition changes :
    - SYSCFG_CFGR3_EN_VREFINT enable bit suppressed. (no more needed and must not be used). 
    - SYSCFG_CFGR3_EN_BGAP define suppressed.
    - SYSCFG_CFGR3_REF_HSI48_RDYF, SYSCFG_CFGR3_SENSOR_ADC_RDYF, SYSCFG_CFGR3_VREFINT_ADC_RDYF, SYSCFG_CFGR3_VREFINT_COMP_RDYF flags suppressed, SYSCFG_CFGR3_VREFINT_RDYF must be used instead (this flag is a combination of the 4 suppressed flags).
    - Added SYSCFG_CFGR3_REF_RC48MHz_RDYF, SYSCFG_CFGR3_REF_HSI48_RDYF, SYSCFG_VREFINT_ADC_RDYF, SYSCFG_CFGR3_SENSOR_ADC_RDYF, SYSCFG_CFGR3_VREFINT_ADC_RDYF and SYSCFG_CFGR3_VREFINT_COMP_RDYF defines.
  • Aligned register namings with the different L0 Reference Manual (For STM32L0x1 : RM0377 Rev5, for STM32L0x2 : RM0367 Rev2, for STM32L0x3 : RM0367 Rev4).
    The list of the modification is listed hereafter :

    • Introduced new masks in EXTI bit definitions in order to simplify LL source code. 
    • Renamed RCC_CFGR_MCO_x into RCC_CFGR_MCOSEL_x
    • Added FLASHSIZE_BASE, UID_BASE and SRAM_SIZE_MAX defines.
    • Renamed macro IS_DMA_ALL_INSTANCE() to IS_DMA_STREAM_ALL_INSTANCE().
