Section 1 STM32CubeH7 main features describes the main features of the STM32CubeH7 MCU Package. Section 2 STM32CubeH7 architecture overview and Section 3 STM32CubeH7 MCU Package overview provide an overview of the STM32CubeH7 architecture and MCU Package structure. UM2204 - Rev 7 - April 2020 For further information contact your local STMicroelectronics sales office. www.st.com UM2204 STM32CubeH7 main features 1 STM32CubeH7 main features STM32CubeH7 MCU Package runs on STM32H7 32-bit microcontrollers based on Arm® Cortex®-M processors. The STM32H7 products come with different lines mainly single core lines based on Cortex®-M7 and dual core lines based on a Cortex®-M7 + Cortex®-M4 architecture. STM32CubeH7 gathers together, in a single package, all the generic embedded software components required to develop an application on STM32H7 microcontrollers. This set of components is highly portable, not only within the STM32H7 Series but also to other STM32 Series. STM32CubeH7 is fully compatible with STM32CubeMX code generator that allows the user to generate initialization code. The package includes low-layer (LL) and hardware abstraction layer (HAL) APIs that cover the microcontroller hardware, together with an extensive set of examples running on STMicroelectronics boards. The HAL and LL APIs are available in an open-source BSD license for user convenience. They 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. The STM32CubeH7 MCU Package also contains a set of middleware components with the corresponding 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 • Graphics: – STemWin, a professional graphical stack solution available in binary format and based on the emWin solution from ST's partner SEGGER – LibJPEG, an open source implementation on STM32 for JPEG images encoding and decoding – TouchGFX, a professional graphical stack solution from STMicroelectronics to create revolutionizing embedded graphical user interfaces (GUIs) with high-end graphics and maximum performance on energy efficient STM32 microcontrollers. • Audio: – PDM2PCM library, offering a solution to decimate and filter out a pulse density modulated (PDM) stream from a digital microphone, in order to convert it to a pulse code modulated (PCM) signal output stream. • • • • • • CMSIS-RTOS implementation with FreeRTOS™ open source solution. This RTOS solution comes with dedicated communications primitives (Stream Buffers and Message Buffers), allowing to pass data from an interrupt service routine to a task, or from one core to another in STM32H7 dual core lines. OpenAMP , an AMP framework providing software components that enable development of software applications for asymmetric multiprocessing (Cortex®-M7 and Cortex®-M4 in STM32H7 dual lines). 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 mbedTLS Network Interface: – STM32_Network_Library provides APIs to access network services on STM32 devices. It supports several network adapters and protocols required by STM32Cube application using network services. Several demonstrations implementing these middleware components are also provided in the STM32CubeH7 MCU Package.

UM2204 - Rev 7 page 3/28 UM2204 STM32CubeH7 architecture overview 2 STM32CubeH7 architecture overview The STM32CubeH7 firmware solution is built around three independent levels that can easily interact with each other as described in Figure 3. STM32CubeH7 firmware architecture . Figure 2. STM32CubeH7 firmware architecture Level 2 Evaluation, Discovery and Nucleo boards demonstration Applications Level 1 Library and protocol based components (for example FatFS, FreeRTOS, OpenAmp, USB Device) Examples BSP drivers Level 0 Hardware abstraction layer (HAL) Core drivers (optional) Low layer (LL) HAL 2.1 Level 0 This level is divided into three sub-layers: • Board support package (BSP) • Hardware abstraction layer (HAL) • Low layer drivers • Basic peripheral usage examples 2.1.1 Board support package (BSP) This layer offers a set of APIs relative to the hardware components in the hardware boards (such as Audio codec, I/O expander, Touchscreen, SRAM driver or LCD drivers). It is composed of two parts: • Component This is the driver related to the external device on the board and not related to the STM32, the component driver provides specific APIs to the BSP driver external components and can be ported to any board. UM2204 - Rev 7 page 4/28 UM2204 Level 0 • BSP driver It allows linking the component driver to a specific board and provides a set of user-friendly APIs. The API naming rule is BSP_FUNCT_Action(): ex. BSP_LED_Init(),BSP_LED_On() The BSP is based on a modular architecture allowing an easy porting on any hardware by just implementing the low level routines. 2.1.2 Hardware abstraction layer (HAL) and low-layer (LL) The HAL layer provides the low level drivers and the hardware interfacing methods to interact with the upper layers (application, libraries and stacks). It provides generic, multi instance and function-oriented APIs which simplify the user application implementation by providing ready-to-use processes. As example, for the communication peripherals (I2S, UART…), it includes APIs allowing to initialize and configure the peripheral, manage data transfer based on polling, interrupt or DMA process, and handle communication errors that may raise during communication. The HAL Drivers APIs are split in two categories: • Generic APIs which provide common and generic functions to all the STM32 Series • Extension APIs which provide specific and customized functions for a specific family or a specific part number • The low-layer APIs provide low-level APIs at register level, with better optimization but less portability. They require a deep knowledge of MCU and peripheral specifications. The LL drivers are designed to offer a fast light-weight expert-oriented layer which is closer to the hardware than the HAL. Contrary to the HAL, LL APIs are not provided for peripherals where optimized access is not a key feature, or for those requiring heavy software configuration and/or complex upper-level stack. The LL drivers feature: – A set of functions to initialize peripheral main features according to the parameters specified in data structures – A set of functions used to fill initialization data structures with the reset values corresponding to each field – Function for peripheral de-initialization (peripheral registers restored to their default values) – A set of inline functions for direct and atomic register access – Full independence from HAL and capability to be used in standalone mode (without HAL drivers) – Full coverage of the supported peripheral features. • Dual Core implementation: – The same HAL/LL drivers support both the single and dual core STM32H7 lines ◦ In the STM32H7 dual core devices all peripherals can be accessed in the same way by the two cores (Cortex®-M7 and Cortex®-M4). It means there is no peripherals split or default allocation between Cortex®-M7 and Cortex®-M4. For this reason the same peripheral HAL and LL drivers are shared between the two cores. ◦ Furthermore, some peripherals ( mainly: RCC, GPIO, FLASH, PWR, HSEM..) have additional dual core specific features: • “DUAL_CORE” define is used to delimit code (defines , functions, macros.. ) available only in dual core line. • “CORE_CM4” define is used to delimit code where we a specific configuration/code portion for Cortex®-M4 core • “CORE_CM7” define is used to delimit code where we a specific configuration/code portion for Cortex®-M7 core on a dual core line. 2.1.3 Basic peripheral usage examples This layer contains the examples of the basic operation of the STM32H7 peripherals using either the HAL APIs as well as the BSP resources. UM2204 - Rev 7 page 5/28 UM2204 Level 1 2.2 Level 1 This level is divided into two sub-layers: 2.2.1 Middleware components Middleware components are a set of libraries covering USB Host and Device Libraries, STemWin, TouchGFX, LibJPEG, FreeRTOS™, OpenAMP, FatFS, LwIP, mbedTLS, and PDM2PCM audio library. Horizontal interactions between the components of this layer are performed directly by calling the feature APIs while the vertical interaction with the low level drivers is done through specific callbacks and static macros implemented in the library system call interface. As example, the FatFs implements the disk I/O driver to access microSD drive or the USB Mass Storage Class. 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) – Support of multipacket transfer features: allows sending big amounts of data without splitting them into max packet size transfers. – Use of configuration files to change the core and the library configuration without changing the library code (read-only). – 32-bit aligned data structures to handle DMA-based transfer in High-speed modes. – Support of multi USB OTG core instances from user level through configuration file (that allows an operation with more than one USB host/device peripheral). – RTOS and Standalone operation – The link with low-level driver through an abstraction layer using the configuration file to avoid any dependency between the Library and the low-level drivers. • STemWin Graphical stack – Professional grade solution for GUI development based on Segger’s emWin solution – Optimized display drivers – Software tools for code generation and bitmap editing (STemWin Builder…) • LibJPEG – Open source standard – C implementation for JPEG image encoding and decoding. • TouchGFX Graphical stack – Professional graphical stack solution from STMicroelectronics – Allotting to create revolutionizing embedded graphical user interfaces (GUIs) with high-end graphics and maximum performance on energy efficient STM32 microcontrollers • FreeRTOS – Open source standard – CMSIS compatibility layer – Tickless operation during low-power mode – Integration with all STM32Cube middleware modules • OpenAmp AMP framework providing for asymmetric multiprocessing (Cortex®-M7 and Cortex®-M4 in STM32H7 dual lines) FAT 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 class LwIP TCP/IP stack – Open source standard – RTOS and standalone operation – • • UM2204 - Rev 7 page 6/28 UM2204 Level 2 • • 2.2.2 PDM2PCM audio library – Sampling rate of 16 kHz with a 16-bit resolution – Various decimation factors to adapt to various PDM clocks – Configurable digital microphone gain with 1 dB step in the range of -12 dB to +51 dB STM32_Network_Library – APIs for accessing network services on STM32 devices – Several network adapters and protocols Examples 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. 2.3 Level 2 This level is composed of a single layer which is a global real-time and graphical demonstration based on the middleware service layer, the low level abstraction layer and the basic peripheral usage applications for boardbased features. Dual core examples and applications follow a dedicated architecture: • In dual core lines, only one project (one workspace) per example/application is provided. This is to be compatible with legacy (single core lines) offer. • Two target projects configuration per workspace (one per core) named STM32YYxx_CM7 and STM32YYxx_CM4. • Each target configuration has its own option settings: target device, linker options, RO, RW zones, preprocessor symbols (CORE_CMx , CORE_CMy) so that user code can be compiled, linked and programmed separately for each core. The compilation results in 2 binaries: CM7 binary and CM4 binary. Figure 3. Dual core project architecture UM2204 - Rev 7 page 7/28 UM2204 Level 2 Figure 4. Dual core project linker file UM2204 - Rev 7 page 8/28 UM2204 STM32CubeH7 MCU Package overview 3 STM32CubeH7 MCU Package overview 3.1 Supported STM32H7 devices and hardware STM32Cube offers a highly portable Hardware Abstraction Layer (HAL) built around a generic and modular architecture. It allows the upper layers, the middleware and application, to implement its functions without knowing, in-depth, the MCU used. This improves the library code re-usability and guarantees an easy portability from one device to another. The STM32CubeH7 offers a full support for all the STM32H7 devices. The user only needs to define the right macro in the stm32h7xx.h file. Table 1. Macros for STM32H7 Series lists which macro to define depending on the used STM32H7 Series device. This macro can also be defined in the compiler preprocessor. Table 1.

Create your project: to create a new project you can either start from the Template project provided for each board under \Projects\\Templates or from any available project under \Projects \\Examples or \Projects\\Applications ( refers to the board name, ex. STM32H743I_EVAL). The Template project provides an empty main loop function, it is a good starting point to get familiar with the project settings for STM32CubeH7. The template has the following characteristics: a. It contains sources of the HAL, CMSIS and BSP drivers which are the minimum required components to develop code for a given board b. It contains the include paths for all the firmware components c. It defines the STM32H7 device supported, allowing to have the right configuration for the CMSIS and HAL drivers d. 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 device Note: UM2204 - Rev 7 When copying an existing project to another location, make sure to update the include paths. 2. Add the necessary middleware to your project (optional): the available middleware stacks are: USB Host and Device Libraries, STemWin, LibJPEG, FreeRTOS™, FatFS, LwIP, and mbedTLS. To find out which source files you need to add to the project files list, refer to the documentation provided for each middleware, you may also have a look at the applications available under \Projects\STM32xx_xxx\Applications \ ( refers to the Middleware stack, for example USB_Device) to get a better idea 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, it has to be copied 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 needs to call HAL_Init() API to initialize the HAL Library, which does the following: a. Configure the SysTick to generate an interrupt every 1ms. The SysTick is clocked by the HSI (default configuration after reset). b. Sets NVIC Group Priority to 4. c. Calls the HAL_MspInit() callback function defined in user file stm32h7xx_hal_msp.c to do the global low level hardware initialization. 5. Configure the system clock: the system clock configuration is done by calling the following APIs: a. HAL_RCC_OscConfig(): configures the internal and/or external oscillators, PLL source and factors. The user may select to configure one oscillator or all oscillators. The PLL configuration can be skipped if there is no need to run the system at high frequency. b. HAL_RCC_ClockConfig(): configures the system clock source, Flash latency and AHB and APB prescalers. page 19/28 UM2204 Developing your own application 6. 7. Peripheral initialization a. Start by writing the peripheral HAL_PPP_MspInit function. For this function, proceed as follows: ◦ Enable the peripheral clock. ◦ Configure the peripheral GPIOs. ◦ Configure DMA channel and enable DMA interrupt (if needed). ◦ Enable peripheral interrupt (if needed). b. Edit the stm32h7xx_it.c to call the required interrupt handlers (peripheral and DMA), if needed. c. Write process complete callback functions if you plan to use peripheral interrupt or DMA. d. In your main.c file, initialize the peripheral handle structure, then call the function HAL_PPP_Init() to initialize your peripheral. 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 accommodate any 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 middleware stacks provided within STM32CubeH7, it can be a good starting point for your development. Note: In the default HAL implementation, the SysTick timer is the timebase source. It is used to generate interrupts at regular time intervals. If HAL_Delay() is called from peripheral ISR process, the SysTick interrupt must have higher priority (numerically lower) than the peripheral interrupt. Otherwise, the caller ISR process is blocked. Functions affecting timebase configurations are declared as __Weak to make override possible in case of other implementations in user file (using a general purpose timer for example or other time source). For more details please refer to HAL_TimeBase example. 4.2.2 LL application This section describes the steps needed to create your own LL application using STM32CubeH7. 1. Create your project To create a new project you either start from the Templates_LL project provided for each board under \Projects\\Templates_LL or from any available project under \Projects\\Examples_LL ( refer to the board name, such as NUCLEO-H743ZI). The Template project provides an empty main loop function, however it is a good starting point to get familiar with project settings for STM32CubeH7. The Template main characteristics are the following: – It contains the source codes of the LL and CMSIS drivers which are the minimal components needed to develop code on a given board. – It contains the include paths for all the required firmware components. – It selects the supported STM32H7 device and allows to configure the CMSIS and LL drivers accordingly. – It provides ready-to-use user files, that are pre-configured as follows: main.c: system clock configuration for maximum frequency. UM2204 - Rev 7 page 20/28 UM2204 Using STM32CubeMX to generate the initialization C code 2. Port an existing project to another board To port an existing project to another target board, start from the Templates_LL project provided for each board and available under \Projects\\Templates_LL: a. Select a LL example To find the board on which LL examples are deployed, refer to the list of LL examples STM32CubeProjectsList.html, to Table 3: Number of examples for each board or to application note “STM32Cube firmware examples for STM32H7 Series” (AN5033) b. Port the LL example i. Copy/paste the Templates_LL folder (to keep the initial source, or directly update existing Templates_LL project). ii. Then porting consists principally in replacing Templates_LL files by the Examples_LL targeted project. Keep all board specific parts. For reasons of clarity, board specific parts have been flagged with specific tags: /* ======== BOARD SPECIFIC CONFIGURATION CODE BEGIN ============== */ ... /* ============== BOARD SPECIFIC CONFIGURATION CODE END ========== */ Thus the main porting steps are the following: 1. Replace the stm32h7xx_it.h file 2. Replace the stm32h7xx_it.c file 3. Replace the main.h file and update it. 4. Replace the main.c file and update it Thanks to these adaptations, the example should be functional on the targeted board. 4.3 Using STM32CubeMX to generate the initialization C code An alternative to steps 1 to 6 described in Section 4.2 Developing your own application consists in using the STM32CubeMX tool to easily generate code for the initialization of the system, the peripherals and middleware (steps 1 to 6 above) through a step-by-step process: 1. Select the STMicroelectronics STM32 microcontroller that matches the required set of peripherals. 2. Configure each required embedded software thanks to a pinout-conflict solver, a clock-tree setting helper, a power consumption calculator, and an utility performing MCU peripheral configuration (GPIO, USART...) and middleware stacks (USB, TCP/IP...). 3. Generate the initialization C code based on the configuration selected. This code is ready to be used within several development environments. The user code is kept at the next code generation. For more information, please refer to “STM32CubeMX for STM32 configuration and initialization C code generation” user manual (UM1718). 4.4 Getting STM32CubeH7 release updates STM32CubeH7 MCU Package releases and patches are available from http://www.st.com/stm32h7. They can be retrieved by clicking the CHECK FOR UPDATE menu within STM32CubeMX. For more details, refer to Section 3 of "STM32CubeMX for STM32 configuration and initialization C code generation" user manual (UM1718). UM2204 - Rev 7 page 21/28 UM2204 FAQs 5 FAQs What is the license scheme for the STM32CubeH7 MCU Package? The HAL is distributed under a non-restrictive BSD (Berkeley Software Distribution) license. 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 mbedTLS) have user-friendly license terms. For more details, refer to the license agreement of each middleware. What boards are supported by the STM32CubeH7 MCU Package? The STM32CubeH7 MCU Package provides BSP drivers and ready-to-use examples for the following STM32H7 boards: NUCLEO-H723ZG, NUCLEO-H743ZI, NUCLEO-H745ZI-Q, NUCLEO-H7A3ZI-Q, STM32H743I-EVAL, STM32H735G-DK, STM32H745I-DISCO, STM32H747I-DISCO, STM32H750B-DK, STM32H7B3I-DK, STM32H747I-EVAL, and STM32H7B3I-EVAL. Does the HAL take benefit from interrupts or DMA? How can this be controlled? Yes. The HAL supports three API programming models: polling, interrupt and DMA (with or without interrupt generation). Are any examples provided with the ready-to-use toolset projects? Yes. STM32CubeH7 provides a rich set of examples and applications (around 192 for STM32H743I-EVAL, 97 for STM32H747I-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 their peripherals and software. This enables the tool to provide a graphical representation to the user and generate *.h/*.c files based on user configuration. How to get regular updates on the latest STM32CubeH7 firmware releases? Refer to Section 4.4 Getting STM32CubeH7 release updates. Does the HAL/LL drivers support all STM32H7 lines single core, dual core and value line ? Yes the HAL/LL drivers support all the STM32H7 lines: • “DUAL_CORE” define is used to delimit code (defines , functions, macros.. ) available only in dual core line. This define is automatically available when user defines the right macro in stm32h7xx.h (see Table 1. Macros for STM32H7 Series). • “CORE_CM4” or “CORE_CM7” defines are respectively used to delimit configuration/code specific to Cortex®‑M4/Cortex®-M7 core. It shall be added by user into compiler preprocessor symbols for each target configuration (see Section 2.3 section "2.3 Level 2"). • Value line devices (STM32H750xx) are treated like single core devices. What are the considerations to run a dual core example: Make sure to compile and build both Cortex®-M7 and Cortex®-M4 targets, then load the corresponding images into the the STM32H7 dual core device. Please refer to the readme.txt for each example. UM2204 - Rev 7 page 22/28 UM2204 FAQs What are the considerations to run a Value line example (STM32H750xx on STM32H750B-DK board, STM32H7B0xx on STM32H7B3I-DK/STM32H7B3I-EVAL board, and STM32H730xx on STM32H735G-DK): Make sure to compile, build and load the ExtMem_Boot into the internal Flash memory.
