Copyright © 2015 STMicroelectronics

 

Update history

V1.3.3 / 20-April-2015

Main Changes

  • V1.3.3 official release, no changes vs. release candidate version (V1.3.3RC1)

V1.3.3RC1 / 15-July-2014

Main Changes

  • stm32l1xx.h
    • Add UID registers mapping
    • Add product categories information
    • Add FLASH WRPR4 register definition
      • IMPORTANT NOTE: In the StdLib, the naming of WRP registers is shifted vs. the Reference Manual:
        • WRPR correspond to WRPR1
        • WRPR1 correspond to WRPR2
        • WRPR2 correspond to WRPR3
        • WRPR3 correspond to WRPR4

V1.3.2 / 10-April-2014

Main Changes

  • Update startup files for EWARM toolchain to cope with compiler enhancement of the V7.10 version.

V1.3.1 / 06-March-2014

Main Changes

  • stm32l1xx.h: update RAM functions attribute definition for GNU compiler

V1.3.0 / 31-January-2014

Main Changes

  • Add support for STM32L1xx XL-density devices "Ultra Low Power XL-density devices: STM32L151xExx, STM32L152xExx and STM32L162xExx"
  • Add new startup file startup_stm32l1xx_xl.s for all toolchains
  • stm32l1xx.h
    • Add new macro STM32L1XX_XL for XL-density devices
    • Update IRQn enumeration for STM32L1XX_XL
    • GPIO BRR register is declared only for STM32L1XX_HD and STM32L1XX_XL devices
    • All devices definition (i.e. STM32L1XX_xx) are commented out, user need to define the right STM32L1xx device in the toolchain compiler preprocessor
    • Extend HSE_STARTUP_TIMEOUT and HSI_STARTUP_TIMEOUT values to 0x5000

V1.2.1 / 19-June-2013

Main Changes

  • stm32l1xx.h
    • Update RI_TypeDef structure by adding registers RI_ASMRx, RI_CMRx and RI_CICRx (x=1..5)
    • Add bits definition for registers RI_ASMRx, RI_CMRx and RI_CICRx (x=1..5)

V1.2.0 / 22-February-2013

Main Changes

  • stm32l1xx.h
    • List of supported devices: add reference to STM32L100xx Ultra Low Power Value Line devices
    • Add SPRMOD bit definition in FLASH_OBR register
    • Add RDERR bit definition in FLASH_SR register
    • Rename FLASH_OBR_nRST_BFB2 to FLASH_OBR_BFB2
    • Delete FLASH_OBR_USER define (useless)

V1.1.1 / 05-March-2012

Main Changes

    • Add new product define: "#define STM32L1XX_MDP"
    • Add new product define: "#define STM32L1XX_HD"
    • Change the library version to V1.1.0
    • Add new IRQ to support STM32L1XX_HD and STM32L1XX_MDP vector table
    • Add new and update some Typedef to support new peripherals (AES, SDIO, OPAMP, FSMC, I2S)
    • Add new peripherals address mapping
    • Update bits definition
  • Add new startup file "startup_stm32l1xx_mdp.s" for all toolchains
  • Add new startup file "startup_stm32l1xx_hd.s" for all toolchains
  • Change the RTC "CAL" register name to "CALR"
  • Update registers bits definitions.
