In line withthe STM32Cube initiative, this set of components is highly portable, not only within theSTM32F4 series but also to other STM32 series.STM32CubeF4 is fully compatible with STM32CubeMX code generator that allows the userto generate initialization code. The package includes a low level hardware abstraction layer(HAL) that covers the microcontroller hardware, together with an extensive set of examplesrunning on STMicroelectronics boards. The HAL is available in an open-source BSD licensefor user convenience.STM32CubeF4 package also contains a set of middleware components with thecorresponding examples. They come with very permissive license terms:Full USB Host and Device stack supporting many classes.–Host Classes: HID, MSC, CDC, Audio, MTP –Device Classes: HID, MSC, CDC, Audio, DFU ?STemWin, a professional graphical stack solution available in binary format and based on the emWin solution from ST's partner Segger ?CMSIS-RTOS implementation with FreeRTOS open source solution ?FAT File system based on open source FatFS solution ?TCP/IP stack based on open source LwIP solution ?SSL/TLS secure layer based on open source PolarSSLA demonstration implementing all these middleware components is also provided in theSTM32CubeF4 package.2 STM32CubeF4 architecture overviewThe STM32CubeF4 firmware solution is built around three independent levels that caneasily interact with each other as described in the Figure 1 below:Level 0: This level is divided into three sub-layers:Board Support Package (BSP): this layer offers a set of APIs related to the hardware components on the hardware boards (Audio codec, I/O expander, Touchscreen, SRAMdriver, LCD drivers. etc…) and composed of two parts:–Component: is the driver related to the external device on the board and notrelated to the STM32, the component driver provides specific APIs to the BSPdriver’s external components and can be ported to any board.–BSP driver: it enables the component driver to be linked to a specific board and provides a set of user-friendly APIs. The API naming rule isBSP_FUNCT_Action(): ex. BSP_LED_Init(),BSP_LED_On()It's based on a modular architecture that allows it to be ported easily to any hardwareby just implementing the low level routines.Hardware Abstraction Layer (HAL): this layer provides the low level drivers and theand stacks). It provides generic, multi instance and function-oriented APIs which allowto offload the user application implementation by providing ready-to-use processes. Forexample, for the communication peripherals (I2S, UART…) it provides APIs allowing to6/22DocID025922 Rev 1initialize and configure the peripheral, manage data transfer based on polling, interrupt or DMA process, and manage communication errors that may raise duringcommunication. The HAL Drivers APIs are split in two categories, generic APIs which provides common and generic functions to all the STM32 series and extension APIs which provides specific and customized functions for a specific family or a specific part number.Basic peripheral usage examples: this layer contains examples of basic operation of the STM32F4 peripherals using only the HAL and BSP resources.Level 1: This level is divided into two sub-layers:Middleware components: a set of Libraries covering USB Host and Device Libraries, STemWin, FreeRTOS, FatFS, LwIP, and PolarSSL. Horizontal interactions between the components of this layer are done directly by calling the feature APIs while the vertical interaction with the low level drivers is done through specific callbacks and staticmacros implemented in the library system call interface. For example, the FatFsimplements the disk I/O driver to access microSD drive or the USB Mass StorageClass.The main features of each Middleware component are as follows:USB Host and Device Libraries–Several USB classes supported (Mass-Storage, HID, CDC, DFU, AUDIO, MTP)–Supports multi packet transfer features: allows sending big amounts of data without splitting them into max packet size transfers.–Uses configuration files to change the core and the library configuration without changing the library code (Read Only).–Includes 32-bit aligned data structures to handle DMA-based transfer in High-speed modes.–Supports multi USB OTG core instances from user level through configuration file (allows operation with more than one USB host/device peripheral).–RTOS and Standalone operation–The link with low-level driver is done through an abstraction layer using the configuration file to avoid any dependency between the Library and the low-levelsolution–Optimized display drivers–Software tools for code generation and bitmap editing (STemWin Builder…)FreeRTOS–Open source standard–CMSIS compatibility layer–Tickless operation during low-power mode–Integration with all STM32Cube Middleware modulesDocID025922 Rev 17/22FAT File system–FATFS FAT open source library–Long file name support–Dynamic multi-drive support–RTOS and standalone operation–Examples with microSD and USB host Mass-storage classLwIP TCP/IP stack–Open source standard–RTOS and standalone operationExamples based on the Middleware components: each Middleware component comes with one or more examples (called also Applications) showing how to use it.Integration examples that use several Middleware components are provided as well.Level 2: This level is composed of a single layer which is a global real-time and graphicaldemonstration based on the Middleware service layer, the low level abstraction layer andthe applications that make basic use of the peripherals for board-based functions.8/22DocID025922 Rev 1DocID025922 Rev 19/223STM32CubeF4 firmware package overview 3.1 Supported STM32F4 devices and hardwareSTM32Cube offers a highly portable Hardware Abstraction Layer (HAL) built around ageneric and modular architecture allowing the upper layers, Middleware and Application, toimplement its functions without in-depth knowledge of the MCU being used. This improvesthe library code re-usability and guarantees an easy portability from one device to another.The STM32CubeF4 offers full support for all STM32F4 Series devices. You only have todefine the right macro in stm32f4xx.h.Table 1 below lists which macro to define depending on the STM32F4 device you are using(this macro can also be defined in the compiler preprocessor).STM32CubeF4 features a rich set of examples and demonstrations at all levels making iteasy to understand and use any HAL driver and/or Middleware components.

As an illustration let's consider to run a simple LED toggling example running on the STM32F4-Discovery board:1.After downloading the STM32CubeF4 firmware package, unzip it into a directory of your choice, you just need to ensure that the package structure is not modified (as shown in Figure 3 above).2. Browse to \Projects\STM32F4-Discovery\Examples.3. Open \GPIO, then the \GPIO_EXTI folder.4. Open the project with your preferred toolchain.5. Rebuild all files and load your image into target memory.6. Run the example: each time you press User button 4, the LEDs will toggle (for more details, refer to the example readme file).You will get a quick overview of how to open, build and run an example with the supported toolchains.EWARM–Under the example folder, open the \EWARM subfolder–Open the Project.eww workspace(a)–Rebuild all files: Project->Rebuild all–Load project image: Project->Debug–Run program: Debug->Go(F5)MDK-ARM–Under the example folder, open the \MDK-ARM subfolder–Open the Project.uvproj workspace(a)–Rebuild all files: Project->Rebuild all target files–Load project image: Debug->Start/Stop Debug Session–Run program: Debug->Run (F5)TrueSTUDIO–Open the TrueSTUDIO toolchain–Click on File->Switch Workspace->Other and browse to the TrueSTUDIOworkspace directory–Click on File->Import, select General->'Existing Projects into Workspace' and then click “Next”.–Browse to the TrueSTUDIO workspace directory, select the project–Rebuild all project files: Select the project in the “Project explorer” window then click on Project->build project menu.–Run program: Run->Debug (F11)a.The workspace name may change from one example to anotherDocID025922 Rev 115/22Getting started UM17304.2 How to develop your own applicationThis section describes the required steps needed to create your own application usingSTM32CubeF4.1.Create your project: to create a new project you can either start from the Templateproject provided for each board under \Projects\\Templates or fromany available project under \Projects\\Examples orSTM32F4-Discovery).The Template project provides an empty main loop function, this is a good starting pointto allow you to get familiar with the project settings for STM32CubeF4. It has thefollowing characteristics:a) It contains sources of the HAL, CMSIS and BSP drivers which are the minimumrequired components to develop code for a given boardb) It contains the include paths for all the firmware componentsc) It defines the STM32F4 device supported, allowing to have the right configurationfor the CMSIS and HAL driversd) It provides ready-to-use user files preconfigured as follows:- HAL is initialized- SysTick ISR implemented for HAL_Delay() purpose- System clock is configured with the maximum frequency of the deviceNote:If you copy an existing project to another location, then you need to update the include paths.2. Add the necessary Middleware to your project (optional): available Middlewarestacks are: USB Host and Device Libraries, STemWin, FreeRTOS, FatFS, LwIP, andPolarSSL. To find out which source files you need to add to the project files list, refer tothe documentation provided for each Middleware, you can also have a look at theapplications available under \Projects\STM32xx_xxx\Applications\( refers to the Middleware stack, for example USB_Device) to get a betteridea of the source files to be added and the include paths.3. Configure the firmware components: the HAL and Middleware components offer a set of build time configuration options using macros declared with “#define” in a header file. A template configuration file is provided within each component, which you have to copy to the project folder (usually the configuration file is named xxx_conf_template.h. The word “_template” needs to be removed when copying it to the project folder). The configuration file provides enough information to know the effect of each configuration option. More detailed information is available in the documentation provided for each component.4. Start the HAL Library: after jumping to the main program, the application code needsUM1730Getting started5. Configure the system clock: the system clock configuration is done by calling these two APIsa) HAL_RCC_OscConfig(): configures the internal and/or external oscillators, PLL source and factors. You can choose to configure one oscillator or all oscillators.You can also skip the PLL configuration if there is no need to run the system athigh frequencyb) HAL_RCC_ClockConfig(): configures the system clock source, Flash latency and AHB and APB prescalers6. Develop your application process: at this stage, your system is ready and you can start developing your application code.a) The HAL provides intuitive and ready-to-use APIs for configuring the peripheral, and supports polling, interrupt and DMA programming models, to accommodateany application requirements. For more details on how to use each peripheral,refer to the rich examples set provided.b) If your application has some real-time constraints, you can find a large set of examples showing how to use FreeRTOS and integrate it with all Middlewarestacks provided in STM32CubeF4, it can be a good starting point for yourdevelopment.c) IMPORTANT NOTE: care must be taken when using HAL_Delay(). This functionprovides an accurate delay (in milliseconds) based on a variable incremented inSysTick ISR. This implies that if HAL_Dely() is called from a peripheral ISRprocess, then the SysTick interrupt must have the highest priority (numericallylower) than the peripheral interrupt. Otherwise the caller ISR process will beblocked. To change the SysTick interrupt priority, you have to use theHAL_NVIC_SetPriority() function.4.3 Using STM32CubeMX for generating the initialization C codeAnother alternative to Steps 1 to 5 described in Section 4.2 consists in using theSTM32CubeMX tool to easily generate code for the initialization of the system, theperipherals and middleware (Steps 1 to 5 above) through a step-by-step process:Selection of the STMicroelectronics STM32 microcontroller that matches the required set of peripherals. Configuration of each required embedded software thanks to a pinout-conflict solver, a clock-tree setting helper, a power consumption calculator, and an utility performingMCU peripheral configuration (GPIO, USART...) and middleware stacks (USB,TCP/IP...).Generation of the initialization C code based on the configuration selected. This code is ready to be used within several development environments.

The Middleware stacks made by ST (USB Host and Device Libraries, STemWin) come with a licensing model allowing easy reuse, provided it runs on an ST device.The Middleware based on well-known open-source solutions (FreeRTOS, FatFs, LwIP and PolarSSL) have user-friendly license terms. For more details, refer to the license agreement of each Middleware.What boards are supported by the STM32CubeF4 firmware package?The STM32CubeF4 firmware package provides BSP drivers and ready-to-use examples for the following STM32F4 boards: STM324x9I_EVAL, STM324xG_EVAL, STM32F4-Discovery, STM32F401-Discovery, STM32F429I-Discovery, STM32F4xx-Nucleo.Is there any link with Standard Peripheral Libraries?The STM32Cube HAL Layer is the replacement of the Standard Peripheral Library.The HAL APIs offer a higher abstraction level compared to the standard peripheral APIs. HAL focuses on peripheral common functionalities rather than hardware. The higher abstraction level allows to define a set of user friendly APIs that can be easily ported from one product to another.Customers currently using Standard Peripheral Libraries will be helped through Migration guides. Existing Standard Peripheral Libraries will be supported, but not recommended for new designs.Does the HAL take benefit from interrupts or DMA? How can this becontrolled?without interrupt generation).Are any examples provided with the ready-to-use toolset projects?Yes. STM32CubeF4 provides a rich set of examples and applications (140 forSTM324x9I_EVAL). They come with the preconfigured project of several toolsets: IAR, Keil and GCC.How are the product/peripheral specific features managed?The HAL offers extended APIs, i.e. specific functions as add-ons to the common API to support features available on some products/lines only.How can STM32CubeMX generate code based on embedded software?STM32CubeMX has a built-in knowledge of STM32 microcontrollers, including theirperipherals and software. This enables the tool to provide a graphical representation to the user and generate *.h/*.c files based on user configuration.DocID025922 Rev 119/22。
