2.1
Level 0
This level is divided into three sub-layers:
•
•
Board Support Package (BSP)
Hardware Abstraction Layer (HAL)
•
Basic peripheral usage examples.
DocID027272 Rev 2
7/23
22
STM32CubeF1 architecture overview
2.1.1
UM1847
Board Support Package (BSP)
This layer offers a set of APIs relative to the hardware components in the hardware boards
(LCD drivers, MicroSD, …). It is composed of two parts:
•
Component
This is the driver relative to the external device on the board and not to the STM32. The
component driver provide specific APIs to the BSP driver external components and
could be portable on any other board.
•
BSP driver
It allows linking the component driver to a specific board and provides a set of userfriendly APIs. The API naming rule is BSP_FUNCT_Action().
Example: 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)
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 multiinstance feature-oriented APIs which simplify user application implementation by providing
ready to use process. As example, for the communication peripherals (I2S, UART…), it
provides APIs allowing initializing and configuring the peripheral, managing data transfer
based on polling, interrupt or DMA process, and handling communication errors that may
raise during communication. The HAL driver APIs are split in two categories:
2.1.3
•
Generic APIs which provides common and generic functions to all the STM32 series
•
Extension APIs which provides specific and customized functions for a specific family
or a specific part number.
Basic peripheral usage examples
This layer includes the examples build over the STM32 peripheral using only the HAL and
BSP resources.
2.2
Level 1
This level is divided into two sub-layers:
•
•
2.2.1
Middleware components
Examples based on the middleware components.
Middleware components
The middleware is a set of libraries covering USB Host and Device Libraries, STemWin,
FreeRTOS, FatFS and LwIP. Horizontal interactions between the components of this layer is
done 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. For example, the FatFs implements the disk I/O driver to access
microSD drive or the USB Mass Storage Class.

DocID027272 Rev 2
UM1847
STM32CubeF1 architecture overview
The main features of each middleware component are as follows:
•
•
•
•
•
2.2.2
USB Host and Device Libraries
–
Several USB classes supported (Mass-Storage, HID, CDC, DFU).
–
Support of multi-packet transfer features that allows sending big amounts of data
without splitting them into maximum 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. This allows to perform operations with more than one USB host/device
peripheral.
–
RTOS and Standalone operation.
–
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…).
FreeRTOS
–
Open source standard.
–
CMSIS compatibility layer.
–
Tickless operation during low-power mode.
–
Integration with all STM32Cube middleware modules.
FAT File system
–
FATFS FAT open source library.
–
Long file name support.
–
Dynamic multi-drive support.
–
RTOS and standalone operation.
–
Examples with microSD.
LwIP TCP/IP stack
–
Open source standard.
–
RTOS and standalone operation.
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 consist in 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 board based features.

STM32CubeF1 firmware package overview
3.1
Supported STM32F1 devices and hardware
STM32Cube offers highly portable Hardware Abstraction Layer (HAL) built around a generic
architecture. It allows the build-upon layers, such as the middleware layer, to implement
their functions without knowing, in-depth, the MCU used. This improves the library code reusability and guarantees an easy portability on other devices.
In addition, thanks to its layered architecture, the STM32CubeF1 offers full support of all
STM32F1 series. The user has only to define the right macro in stm32f1xx.h.
Table 1 gives the macro to be defined depending on the STM32F1 device used. This macro
must also be defined in the compiler preprocessor.

STM32CubeF1 firmware package overview
STM32CubeF1 features a rich set of examples and applications at all levels making it easy
to understand and use any HAL driver and/or middleware components. These examples are
running on STMicroelectronics boards as listed in Table 2.

STM32F103xB
As for all other STM32 Nucleo boards, the NUCLEO-F103RB feature a reduced set of
hardware components (one user key button and one user LED). To enrich the middleware
support offer for the STM32CubeF1 firmware package, an LCD display Adafruit Arduino™
shield is used. This shield embeds a microSD connector and a joystick in addition to the
LCD.
In the BSP component, the dedicated drivers for the Arduino shield are available. Their use
is illustrated through either the provided BSP example or in the demonstration firmware,
without forgetting the FatFS middleware application.
The STM32CubeF1 firmware is able to run on any compatible hardware. The user simply
updates the BSP drivers to port the provided examples on his own board, if this later has the
same hardware features (LED, LCD display, buttons...).

Running your first example
This section explains how simple is to run a first example within STM32CubeF1. It uses as
illustration the generation of a simple LED toggle running on STM32F103RB Nucleo board:
1.
Download the STM32CubeF1 firmware package. Unzip it into a directory of your
choice. Make sure not to modify the package structure shown in Figure 3. Note that it is
also recommended to copy the package at a location close to your root volume (e.g.
C\Eval or G:\Tests) because some IDEs encounter problems when the path length is
too long.

Getting started with STM32CubeF1
under \Projects\<STM32xxy_yyy>\Examples or \Projects\<STM32xx_yyy>\Applications
(where <STM32xxx_yyy> refers to the board name, e.g. STM3210E_EVAL).
The Template project is providing empty main loop function, however it’s a good
starting point to get familiar with project settings for STM32CubeF1. The template has
the following characteristics:
–
It contains the source code of HAL, CMSIS and BSP drivers which are the minimal
components required to develop a code on a given board.
–
It contains the include paths for all the firmware components.
–
It defines the STM32F1 device supported, thus allowing to configure the CMSIS
and HAL drivers accordingly.
–
It provides read-to-use user files pre-configured as shown below:
HAL initialized with default time base with ARM Core SysTick.
SysTick ISR implemented for HAL_Delay() purpose.
System clock configured with the minimum frequency of the device (HSI) for an
optimum power consumption.
Note:
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 library, LwIP, STemWin,
FreeRTOS and FatFS. To know which source files you need to add in the project files
list, refer to the documentation provided for each middleware. You can also look at the
Applications available under \Projects\STM32xxx_yyy\Applications\<MW_Stack>
(where <MW_Stack> refers to the middleware stack, e.g. USB_Device) to know which
sources files and which include paths have to be added.
3.
Configure the firmware components
The HAL and middleware components offer a set of build time configuration options
using macros # define declared 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 impact 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 must call HAL_Init() API to
initialize the HAL Library, which do the following tasks:
a)
Configuration of the Flash prefetch and SysTick interrupt priority (through macros
defined in stm32f1xx_hal_conf.h).
b)
Configuration of the SysTick to generate an interrupt each 1 ms at the SysTick
TICK_INT_PRIO interrupt priority defined in stm32f1xx_hal_conf.h, which is

clocked by the HSI (at this stage, the clock is not yet configured and thus the
system is running from the internal HSI at 8 MHz).
5.
c)
Setting of NVIC Group Priority to 4.
d)
Call of HAL_MspInit() callback function defined in stm32f1xx_hal_msp.c user file
to perform global low-level hardware initializations.
Configure the system clock
The system clock configuration is done by calling the two APIs described below:
6.
7.
a)
HAL_RCC_OscConfig(): this API configures the internal and/or external
oscillators, as well as the PLL source and factors. The user can choose 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(): this API configures the system clock source, the Flash
memory latency and AHB and APB prescalers.
Initialize the peripheral
a)
First write the peripheral HAL_PPP_MspInit 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 stm32xxx_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
At this stage, your system is ready and you can start developing your application code.
Caution:
18/23
–
The HAL provides intuitive and ready-to-use APIs to configure the peripheral. It
supports polling, interrupts and DMA programming model, to accommodate any
application requirements. For more details on how to use each peripheral, refer to
the rich examples set provided in the STM32CubeF1 package.
–
If your application has some real-time constraints, you can found a large set of
examples showing how to use FreeRTOS and integrate it with all middleware
stacks provided within STM32CubeF1. This can be a good starting point to
develop your application.
In the default HAL implementation, SysTick timer is used as timebase: it generates
interrupts at regular time intervals. If HAL_Delay() is called from peripheral ISR process,
make sure that the SysTick interrupt has higher priority (numerically lower) than the
peripheral interrupt. Otherwise, the caller ISR process will be 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, refer to HAL_TimeBase example.

Getting started with STM32CubeF1
Using STM32CubeMX to generate initialization C code
An alternative to steps 1 to 6 described in Section 4.2 consists in using the STM32CubeMX
tool to generate code to initialize the system, 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 clocktree setting helper, a power consumption calculator, and the utility performing MCU
peripheral configuration (e.g. GPIO or USART) and middleware stacks (e.g. USB).
3.
Generate the initialization C code based on the configuration selected. This code is
ready-to-use within several development environments. The user code is kept at the
next code generation.
For more information, please refer to STM32CubeMX user manual (UM1718).
4.4

FAQ
5.1
What is the license scheme for the STM32CubeF1 firmware?
The HAL is distributed under a non-restrictive BSD (Berkeley Software Distribution) license.
The middleware stacks made by STMicroelectronics (USB Host and Device Libraries,
STemWin) come with a licensing model allowing easy reuse, provided it runs on an
STMicroelectronics device.
The middleware based on well-known open-source solutions (FreeRTOS and FatFs) have
user-friendly license terms. For more details, refer to the license agreement of each
middleware.
5.2
What boards are supported by the STM32CubeF1 firmware
package?
The STM32CubeF1 firmware package provides BSP drivers and ready-to-use examples for
the following STM32F1 boards: STM3210E-EVAL, STM3210C-EVAL,
STM32VLDISCOVERY and NUCLEO-F103RB.
5.3
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.
The HAL focuses on peripheral common features rather than hardware. Its higher
abstraction level allows defining a set of user-friendly APIs that can be easily ported from
one product to another.
Customers currently using Standard Peripheral Libraries have access to migration guides.
Although existing Standard Peripheral Libraries are supported, they are not recommended
for new designs.
5.4
Does the HAL drivers take benefit from interrupts or DMA?
How can this be controlled?
Yes, they do. The HAL layer supports three API programming models: polling, interrupt and
DMA (with or without interrupt generation).
5.5
Are any examples provided with the ready-to-use toolset
projects?
Yes. STM32CubeF1 provides a rich set of examples and applications (around 90). They
come with the pre-configured projects for IAR, Keil and GCC toolchains.

FAQ
How are the product/peripheral specific features managed?
The HAL drivers offer extended APIs, i.e. specific functions as add-ons to the common API
to support features available on some products/lines only.
5.7
How can STM32CubeMX generate code based on embedded
software?
STM32CubeMX has a built-in knowledge of STM32 microcontrollers, including their
peripherals and software, that allows to provide a graphical representation to the user and
generate *.h/*.c files based on user configuration.
5.8
How can I get regular updates on the latest STM32CubeF1
firmware releases?
The STM32CubeF1 firmware package comes with an updater utility, STM32CubeUpdater,
that can be configured for automatic or on-demand checks for new firmware package
updates (new releases or/and patches).
STM32CubeUpdater is integrated as well within the STM32CubeMX tool. When using this
tool for STM32F1 configuration and initialization C code generation, the user can benefit
from STM32CubeMX self-updates as well as STM32CubeF1 firmware package updates.
