STM32CubeL4 Firmware Examples for STM32L4 Series and STM32L4+ Series

Copyright 2017 STMicroelectronics

The STM32CubeL4 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 examples are classified depending on the STM32Cube level they apply to, and are named as follows:

The examples are located under STM32Cube_FW_STM32CubeL4_VX.Y.Z\Projects\, and all of them have the same structure:

To run the example, you have to do the following:

The provided examples can be tailored to run on any compatible hardware; user simply need to update the BSP drivers for his board, if it has the same hardware functions (LED, LCD display, pushbuttons...etc.). The BSP is based on a modular architecture that allows it to be ported easily to any hardware by just implementing the low level routines.

The table below contains the list of examples provided within STM32CubeL4 Firmware package.
