Purpose

STM32WL series will serve all applications requiring Sub-GHz (LoRaWAN, Sigfox) capabilities in a low-power context with an open dual core architecture offer.

STM32Cube is an STMicroelectronics original initiative to ease developers life by reducing development efforts, time and cost.

STM32Cube covers STM32 portfolio.

STM32Cube Version 1.x includes:

• The STM32CubeMX, a graphical software configuration tool that allows to generate C initialization code using graphical wizards.
• A comprehensive embedded software platform, delivered per series (such as STM32CubeWL for STM32WL series)
  • The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio
  • A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics, LoRaWAN, Sigfox

All embedded software utilities come with a full set of examples.

The STM32Cube firmware solution offers a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements.

The HAL (Hardware Abstraction Layer) & LL (Low Layers) drivers provided within this package supports the following STM32WLxx product:

• STM32WL55xx
• STM32WL54xx
• STM32WLE5xx
• STM32WLE4xx

The HAL and LL drivers provided within this package are compliant with MISRA-C®:2012 guidelines, and have been reviewed with a static analysis tool to eliminate possible run-time errors. Reports are available on demand.
