Overview
|
|
********
|
|
|
|
The STM32F0 Discovery development board uses an STM32F051R8T6 MCU and
|
|
integrates the ST-LINK/V2-1 debugger and programmer. It also comes with a
|
|
comprehensive STM32 software HAL library and various packaged software
|
|
examples.
|
|
|
|
More information about the board can be found at the `STM32F0DISCOVERY website`_.
|
|
|
|
Hardware
|
|
********
|
|
|
|
The STM32 Discovery board features:
|
|
|
|
- STM32F051R8T6 microcontroller featuring 64 KB Flash memory, 8 KB RAM in an
|
|
LQFP64 package
|
|
- On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone
|
|
ST-LINK/V2 (with SWD connector for programming and debugging)
|
|
- Board power supply: through USB bus or from an external 5 V supply voltage
|
|
- External application power supply: 3 V and 5 V
|
|
- Four LEDs:
|
|
|
|
- LD1 (red) for 3.3 V power on
|
|
- LD2 (red/green) for USB communication
|
|
- LD3 (green) for PC9 output
|
|
- LD4 (blue) for PC8 output
|
|
- Two push buttons (user and reset)
|
|
- Extension header for all LQFP64 I/Os for quick connection to prototyping board
|
|
and easy probing
|
|
- An additional board is provided which can be connected to the extension
|
|
connector for even easier prototyping and probing.
|
|
- Comprehensive free software including a variety of examples, part of
|
|
STM32CubeF0 package or STSW-STM32049 for legacy Standard Libraries usage
|
|
|
|
More information about STM32F051R8 can be found in the `STM32F0x8 reference manual`_.

==================
|
|
|
|
The Zephyr stm32f0_disco board configuration supports the following hardware features:
|
|
|
|
+-----------+------------+-------------------------------------+
|
|
| Interface | Controller | Driver/Component |
|
|
+===========+============+=====================================+
|
|
| NVIC | on-chip | nested vector interrupt controller |
|
|
+-----------+------------+-------------------------------------+
|
|
| UART | on-chip | serial port-polling; |
|
|
| | | serial port-interrupt |
|
|
+-----------+------------+-------------------------------------+
|
|
| PINMUX | on-chip | pinmux |
|
|
+-----------+------------+-------------------------------------+
|
|
| GPIO | on-chip | gpio |
|
|
+-----------+------------+-------------------------------------+
|
|
| CLOCK | on-chip | reset and clock control |
|
|
+-----------+------------+-------------------------------------+
|
|
| FLASH | on-chip | flash memory |
|
|
+-----------+------------+-------------------------------------+
|
|
| WATCHDOG | on-chip | independent watchdog |
|
|
+-----------+------------+-------------------------------------+
|
|
|
|
Other hardware features are not yet supported in this Zephyr port.
|
|
|
|
The default configuration can be found in
|
|
:zephyr_file:`boards/st/stm32f0_disco/stm32f0_disco_defconfig`
|
|
|
|
Connections and IOs
|
|
===================
|
|
|
|
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
|
|
input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the
|
|
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current
|
|
capable except for analog inputs.
|
|
|
|
Default Zephyr Peripheral Mapping:
|
|
----------------------------------
|
|
|
|
- UART_1_TX : PA9
|
|
- UART_1_RX : PA10
|
|
- UART_2_TX : PA2
|
|
- UART_2_RX : PA3

Programming and Debugging
|
|
*************************
|
|
|
|
STM32F0DISCOVERY board includes an ST-LINK/V2-1 embedded debug tool interface.
|
|
|
|
Applications for the ``stm32f0_disco`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
|
|
so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
|
|
|
|
Alternatively, OpenOCD or JLink can also be used to flash the board using
|
|
the ``--runner`` (or ``-r``) option:
|
|
|
|
.. code-block:: console
|
|
|
|
$ west flash --runner openocd
|
|
$ west flash --runner jlink
|
|
|
|
Flashing an application to Nucleo F030R8
|
|
----------------------------------------
|
|
|
|
Here is an example for the :zephyr:code-sample:`blinky` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: stm32f0_disco
|
|
:goals: build flash
|
|
|
|
You will see the LED blinking every second.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:zephyr:code-sample:`blinky` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: stm32f0_disco
|
|
:maybe-skip-config:
|
|
:goals: debug
|
