USER RECOMMENDATIONS • STM32L1 users: • If only STM32L1 MCUs are required, the Standard Peripheral Library ensures a good portability level between all STM32L1 devices. STM32Cube is still highly recommended for new designs (order code: STSW‑STM32077) • STM32 portability needs: • STM32Cube HAL is the best answer when a high level of portability is required (order codes: STM32CubeL0, STM32CubeL1 and STM32CubeL4) • STM32 optimization needs: www.st.com/stm32embeddedsoftware • STM32Cube LL APIs allow user control down to the register level, thus minimizing software overhead and allowing for power consumption optimization (order codes: STM32CubeL0, STM32CubeL1 and STM32CubeL4) • For STM32L0 users, STM32Snippets allow users to control the hardware with minimal software overhead therefore optimizing power consumption.
