特别推荐
Getting started with STM32L4+
- Order the 144-pin nucleo boards (NUCLEO-L4R5ZI, NUCLEO-L4R5ZI-P or NUCLEO-L4P5ZG) and the discovery kits (32L4R9IDISCOVERY or STM32L4P5G-DK) or the STM32L4R9I-EVAL evaluation kit for STM32L4+ MCUs.
- Download the STM32CubeL4 embedded software package containing the HAL, LL (Low-Layer) APIs, and middleware. Then install ST’s STM32CubeMX graphical software configuration tool that supports pinout configuration, code generation and a power-consumption calculator. Start with one of the many examples provided or build your own project from scratch.
- Watch the STM32L4+ Online Training
- Read the STM32L4+ blog article for further details.
