    • Refer to release notes for further details
  • HAL / LL Drivers updates
    • Maintenance release to fix known defects.
    • Low Layer drivers APIs provide register level programming: they require deep knowledge of peripherals described in STM32L1xx Reference Manual.
    • Low Layer drivers are available for: ADC, COMP, CORTEX, CRC, DAC, DMA, EXTI, GPIO, I2C, IWDG, OPAMP, PWR, RCC, RTC, SPI, TIM, USART, WWDG peripherals and additional Low Level Bus, System and Utilities APIs.
    • Low Layer drivers APIs are implemented as static inline function in new Inc/stm32l1xx_ll_ppp.h files for PPP peripherals, there is no configuration file and each stm32l1xx_ll_ppp.h file must be included in user code.
    • Refer to release notes for further details
  • Projects updates

    • The STM32CubeL1 Firmware package comes with a rich set of examples running on STMicroelectronics boards, organized by board and provided with preconfigured projects for the main supported toolchains. The exhaustive list of projects is provided in this table (STM32CubeProjectsList.html).
