How to create a software pack enhanced for STM32CubeMX using STM32 Pack Creator tool
Introduction
STM32CubeMX is part of the STM32Cube initiative designed to simplify and accelerate the development of applications for
STM32 microcontrollers.
STM32CubeMX offers the possibility to generate C projects using embedded software offers packages as CMSIS-Pack compliant software packs.
Starting with the 6.0.0 revision, STM32CubeMX is delivered with STM32PackCreator, an STM32 pack creation graphical companion tool, whose main purpose is the creation of software packs.
The generated software packs are:
• Arm ® CMSIS-Pack-compliant
• Optionally STM32Cube rules-compliant. Such compliance is mandatory for publishing a pack as an STM32Cube
Expansion Package.
• Optionally enhanced for STM32CubeMX. Such enhancements allow the pack to be configured in the STM32CubeMX user interface and for STM32CubeMX to generate custom code in line with the user's configuration.
This document describes what a software pack is, how to create a software pack from scratch using STM32PackCreator and how to verify the generated pack using STM32CubeMX.
It also provides the list of reference material and specifications that are useful when considering the creation of an STM32Cube
Expansion Package.

Software pack overview
Software pack overview
Definition and CMSIS-Pack standard
•
•
•
•
A software pack is a complete file collection shipped in ZIP-format (renamed to *.pack
).
It complies with Arm ® CMSIS-Pack specifications, which define a standardized way to deliver software components (see https://www.keil.com/pack/doc/CMSIS/Pack/html/index.html
)
It includes:
Source code, header files, and software libraries
Documentation and source code templates
Example projects
The pack .pdsc
file: this file is designed for software development environments. It is an XML-based package description (PDSC) file that describes the content of the software pack and the usage context for the files supplied within the pack (for example, on which conditions, they can be used, if any such condition exists)
For an introduction to CMSIS Packs structure and format of a pack description file (PDSC), check out:
• Keil ® website: https://www.keil.com/pack/doc/CMSIS/Pack/html/index.html
• Keil ® tutorial page: https://www.keil.com/pack/doc/CMSIS/Pack/html/cp_SWComponents.html
Figure 1. Keil ® tutorial cover page
UM2739 - Rev 3
The Arm ® CMSIS-Pack system solves several problems:
• It provides meta-data of files that relate to a software component. All files that belong to a software component can be identified and information about the original provider is preserved.
•
•
It enables consistent software component upgrade and identifies incompatible configuration files that may be part of the user application.
Software component providers can specify the interfaces and relationship to other software components.
•
•
•
The meta-data of a software component can include dependency information for toolchains, devices, and processors, which simplifies integration into application programs.
Thousands of software packs have been created by Arm ® and its partners: these can be easily downloaded, installed and used in software projects, using Arm ® development tools, STM32CubeMX, STM32CubeIDE and any other tool supporting the standard (some support in IAR-EWARM).

STM32Cube Expansion Packages
STM32Cube Expansion Packages
On top of the CMSIS-Pack standard, STMicroelectronics specifies some rules to create STM32Cube Expansion
Packages. Refer to the STM32Cube Expansion page on www.st.com
When the option to create an STM32Cube Expansion Package is enabled for the project, STM32PackCreator implements the relevant constraints, like fields that become mandatory, and specific file paths.
Software pack creation cycle
According to the CMSIS-Pack standard, pack owners are responsible for their pack hosting and maintenance.
Refer to
.
The Arm ® CMSIS-Pack standard is designed as a web-based distribution network. Each provider of a CMSIS-
Pack (also referred to as vendor) is responsible for hosting, maintaining, and publishing unique versions of a
CMSIS-Pack.
A CMSIS-Pack is uniquely identified by <vendor>.<pack name>.<version>.pack. All published versions of a pack and the PDSC file need to be available in the same web folder specified by <url>. Multiple different packs may be located in the same web folder.
Refer to https://www.keil.com/pack/doc/CMSIS/Pack/html/packIndexFile.html

Principles
•
•
Historically, pack developers must perform manual updates of XML files, run several scripts and launch different toolsets to ensure things worked out as expected.
Today pack developers can rely on a single tool, STM32PackCreator, to get guidance, avoid errors and generate the pack in one click.
With STM32PackCreator, pack developer may:
Describe and package their software offers as packs,
Enhance the pack to accelerate the process of application creation by end-users,
– Introduce configuration parameters for users to automatically generate the configuration relevant for their application using STM32CubeMX. From the STM32CubeMX user interface, the user can set the values of configurable software component parameters and retrieve them as C-code statements in the generated C projects, meaning as #define statements.
– Introduce platform settings when one or more pack components needs to interface with peripherals and GPIOs: users are able, from STM32CubeMX User Interface, to select among a choice of possible peripherals or GPIOs to interface the pack components with and retrieve the corresponding initialization C-code.
•
•
– Introduce custom templates when specific code must be generated according to the user’s configuration: users retrieve advanced C-code aligned with the configuration they required for their application.
Check how the pack appears in the STM32CubeMX user interface using the STM32CubeMX preview feature,
Generate new pack revisions by adding a new release entry in the CMSIS-Pack view and clicking Save &
Generate pack from the File menu.
Pack developers use STM32CubeMX to:
• Verify that the project is generated successfully when the pack is enabled,
• Create pack example projects based on STM32CubeMX generated code.
•
•
•
•
•
•
Key features
STM32PackCreator allows to:
• Create, save, and open previously saved projects.
Create new projects from scratch or existing packs.
Create and update the pack description.
Create and update the pack configuration parameters and platform settings. The users configure them from
STM32CubeMX configuration panel when using the pack in their project.
Select custom code templates. Such templates are used to generate pack related code corresponding to the user’s configuration.
Generate Arm ® CMSIS-Pack compliant packs.
Generate STM32Cube Expansion compliant packs.
Rules and limitations
Compatibility with STM32CubeMX
STM32PackCreator implementation is linked to the STM32CubeMX version embedding it. Also, it is strongly advised to use the same STM32CubeMX version or higher to install packs generated with STM32PackCreator in
STM32CubeMX.
UM2739 - Rev 3 page 6/112
UM2739
Rules and limitations
Compatibility with CMSIS-pack standard
STM32PackCreator generates packs that are compliant with the 1.6.3 standard. Refer to
.
Figure 3. CMSIS-Pack standard compatibility
Note:
Compliance with STM32Cube Expansion rules
STM32PackCreator implements constraints to generate packs that are compliant with STM32Cube Expansion rules. Refer to STM32Cube Expansion Packages in
STM32PackCreator cannot convert an existing pack to become an STM32Cube Expansion Package. The workaround is to create a new pack from scratch using STM32PackCreator and with the STM32Cube compliant option turned on. Refer to

Mandatory for a pack to be configurable with STM32CubeMX.
Creates parameters (name, possible values, location in the user interface, assignment to one or more Pack modes.
Note: Pack modes match the Pack top components and bundle entries defined in the CMSIS pack view.
It is possible to create parameters with conditions on other parameters or mathematical expressions.
For example, enter MOD(32) if the parameter must be a multiple of 32.
Note: An expression builder is available to guide the user.
By choosing expression as a parameter type, it is possible to define parameter values that are based on an expression. For, example a parameter can be derived from another parameter, called Param1 , by using an expression such as expression = Param1/4 .
After applying the changes, the parameter is converted to the String type. Changing back to expression type allows to edit the expression previously defined.

Creating a pack from scratch (step by step procedure)
This section shows the creation of a demonstration pack.
Tips and limitations are provided along the way.
Prepare for pack creation
General approach
In the following, elements highlighted with (*) indicate that they relate to an advanced pack feature and are optional.
The first question to answer is whether or not the pack is an STM32Cube Expansion Package. Going for an
STM32Cube Expansion Package eases the next steps as guidelines are available on how the software offer may be packaged and described.
•
•
•
•
•
The first step is to assess the pack architecture and requirements:
• How must the software offer be organized: which components, which bundle of components, for which categories (Class, Group, etc...)?
• Are there dependencies between components? Are they conditions on components?
Is there any API that must be advertised for other packs to use (*)?
Which components are configurable? What are the configuration parameters?
Are the parameters available on specific conditions only (*)?
Are some components board-dependent (*)? Which GPIOs or peripheral modes are required?
Is there any custom code that must be generated (*)?
•
•
Then, it is strongly recommended to keep one folder holding all the files to be delivered with the pack:
• Source, Header, Documentation files
– Which components/bundles they must belong to.
Freemarker template files (*) used for custom code generation by STM32CubeMX.
Additional files (*)
– Files that are present in the pack but not referenced in the .pdsc
file, such as STM32 HAL driver files necessary for example projects but not required when generating C-projects with STM32CubeMX.
See
for details.

CMSIS-Pack conditions overview and STM32CubeMX restrictions
The CMSIS-Pack standard allows defining conditions and assigning them to components and component files, which then become available only when the condition criteria are met.
Conditions are optional.

Condition rules
Conditions are made of accept, require, and deny rules.
Caution:
Caution:
5.3.8
Accept
Require
Deny
Table 6. Condition rules
At least one accept must be true to signal a true for the complete condition (OR-Rule)
All require must be true to signal a true for the complete condition (AND-Rule).
If one denial is true the complete condition becomes false.
This element overrules require and accept (AND-NOT-Rule)
STM32CubeMX limitation: a rule must not mix conditions of different types ((Device (D), Compiler (T),
Component (C)).
STM32CubeMX limitation: conditions using Dcore may be assigned only on component files at a component or bundle level.
List of pack constraints
PackA components and component files have the following constraints that can be managed using the CMSIS-
Pack condition element.
Constraints for Bundle1
Bundle1 components are only accessible for STM32MCUs embedding Arm ® Cortex ® -M4 or Cortex ® -M7 cores: a
Dcore condition is necessary.
Constraints for TopComponent files
The files are compiled library files. They are copied according to the compiler and the core selected for the user’s project: conditions on Tcompiler and Dcore are necessary.
Constraints for Application components
One Application requires at least one component from Bundle1.
One Application requires at least one component from Bundle1 and the TopComponent component: conditions on components are necessary.

Enhance the pack with platform settings
Platform settings introduction
STM32PackCreator allows pack developers to specify platform requirements for the pack components by clicking
.
Platform settings are optional and may be used to add BSP constraints to the usage of a software component.
• Example: to work, a software component requires an SPI configured in full-duplex master mode or a GPIO in
EXTI mode.
STM32Cube specifications define a set of Board Support Package APIs among which the BSP Bus and BSP
Common driver APIs.
• The BSP bus driver API, which exports the transport functions used by the components IO operations. They can be shared by several IO operations of several external components.
• The BSP common driver API, which provides a set of friendly used APIs for HMI devices, like LEDs, buttons, and joystick, and the board COM ports. The BSP common services are defined only if the corresponding hardware is available on the board.
•
•
STM32CubeMX embeds some default templates to generate the BSP Bus I/O and BSP Common drivers files,
, and can generate accordingly:
BSP bus driver code for I2C, USART, UART, LPUART, and SPI peripherals.
BSP common driver code for LED (GPIO_OUT), Button (GPIO_EXTI), USART/UART/LPUART
Figure 78. STM32CubeMX Freemarker templates for platform settings
UM2739 - Rev 3
The names for the generated files and BSP folder uses STM32 board names when the project is started from
STM32CubeMX board selector. Refer to
Figure 79 and Figure 80 . Otherwise, the
custom convention is used, like custom_bus.h
file.

The BSP common driver code is found under the Drivers/BSP folder. Other BSP code is generated in the user’s folder.
Figure 79. STM32CubeMX generated BSP common driver files
Figure 80. STM32CubeMX generated Bus I/O driver files
Pack developers can write custom Freemarker templates for CubeMX to generate specific code for BSP bus I/O drivers and other custom BSP APIs. Such templates can be added to the pack by clicking
then assigned to the relevant platform setting entry.

Enhance the pack with custom templates
Custom templates introduction
By default, STM32PackCreator generates packs with a default template inside. This allows STM32CubeMX to generate a header file with all pack parameter defines: <Vendor name>.<Pack name>_conf.h
.
STM32PackCreator allows as well pack developers to specify their templates for a given mode of the pack and for a selection of parameters: these custom templates are optional and necessary only when custom C code must be generated using STM32CubeMX.
Freemarker is the language used to write Freemarker templates. For details check out: https:// freemarker.apache.org/ . The pack developers can write custom templates, add them to their packs using
STM32PackCreator and check the generated code using STM32CubeMX.

Enhance the pack with custom templates
STM32CubeMX adds some design constraints for custom code to be generated. Parameters are accessible as
SWIPdatas, as shown in
Figure 91 , and platform settings as BSPName, as shown in

About generating code snippets
The generated file destination can be set to generate code to be included in other generated files. This option is available only to template files with the extension .tmp
. This generates a code snippet that is included in a file generated through another template, which must have an included statement to ensure the code snippet is imported at code generation.
Enhance the pack with application templates
Application components and application templates introduction
Application components are optional
• A pack may come with one or more Application components.
UM2739 - Rev 3 page 97/112
UM2739
Enhance the pack with application templates
•
•
•
Application components can be top components or be part of a bundle.
Application components come with a module name specified in the CMSIS-Pack view.
Only one application can be enabled per project.
The main purpose of application components is for STM32CubeMX to generate application-ready code
• app_<modulename>_Init/Process functions are called by default in main.c
. This generation can be disabled through STM32CubeMX Project Manager > Advanced settings .
• app_<modulename>_Init/Process functions are defined in app_packname.c/.h
files.
There are several options in STM32PackCreator to specify application templates:
• Specify application templates common to all application components of the pack. From the STM32CubeMX landing page, select app_<pack name>_h.ftl
and app_<pack name>_c.ftl
files, as shown in
•
•
Specify a common app_<pack name>_h.ftl
from the STM32CubeMX landing page and for .c
file generation, add a custom template to each application component in the pack.
Do not specify any common pack application template. Add custom templates to each application component in the pack.
Figure 96. Pack application templates
UM2739 - Rev 3
• STM32CubeMX generates the corresponding app_<modulename>.h/.c
files.
They are generated as empty files if the templates are not available in the pack.
Applications RTE Components or Module names
The application custom templates can be designed so that code is generated differently according to the RTE component defines or module names.

Save the project and generate the pack
•
•
Use RTE Components defines:
– RTE Components are specified in the components section of the CMSIS-Pack view.
– Most useful when all applications share the same module name, which is recommended to support multi-pack configurations. Use the following Freemarker statement: #if define?contains(“<RTE component>") .
Use Module names:
– Module names are specified in the components section of the CMSIS-Pack view.
– When applications use different module names and a common template, use the following Freemarker statement: #if ModuleName?contains(“<module name>")
Refer to the X-Cube-BLE2 pack for examples of application templates app_x-cube-ble2_c/_h.ftl
.
Save the project and generate the pack
1.
Go back to the CMSIS-Pack view and create a new 0.0.2 release.
