Overview
4+
********
5+
The STM32 Nucleo-64 development board with STM32F072RB MCU, supports Arduino and ST morpho connectivity.
6+
7+
The STM32 Nucleo board provides an affordable, and flexible way for users to try out new concepts,
8+
and build prototypes with the STM32 microcontroller, choosing from the various
9+
combinations of performance, power consumption, and features.
10+
11+
The Arduino* Uno V3 connectivity support and the ST morpho headers allow easy functionality
12+
expansion of the STM32 Nucleo open development platform with a wide choice of
13+
specialized shields.
14+
15+
The STM32 Nucleo board integrates the ST-LINK/V2-1 debugger and programmer.
16+
17+
The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together
18+
with various packaged software examples.
19+
20+
More information about the board can be found at the `Nucleo F072RB website`_.
21+
22+

46+
- USB re-enumeration capability. Three different interfaces supported on USB:
47+
48+
- Virtual COM port
49+
- Mass storage
50+
- Debug port
51+
52+
More information about STM32F072RB can be found in
53+
the `STM32F072 reference manual`_ .
54+
55+
56+

57+
==================
58+
59+
The Zephyr ``nucleo_f072rb`` board supports the following hardware features:
60+
61+
+-----------+------------+-------------------------------------+
62+
| Interface | Controller | Driver/Component |
63+
+===========+============+=====================================+
64+
| NVIC | on-chip | nested vector interrupt controller |
65+
+-----------+------------+-------------------------------------+
66+
| UART | on-chip | serial port-polling; |
67+
| | | serial port-interrupt |
68+
+-----------+------------+-------------------------------------+
69+
| PINMUX | on-chip | pinmux |
70+
+-----------+------------+-------------------------------------+
71+
| GPIO | on-chip | gpio |
72+
+-----------+------------+-------------------------------------+
73+
| CLOCK | on-chip | reset and clock control |
74+
+-----------+------------+-------------------------------------+
75+
| FLASH | on-chip | flash memory |
76+
+-----------+------------+-------------------------------------+
77+
| WATCHDOG | on-chip | independent watchdog |
78+
+-----------+------------+-------------------------------------+
79+

81+
| SPI | on-chip | SPI controller |
82+
+-----------+------------+-------------------------------------+
83+
| RTC | on-chip | rtc |
84+
+-----------+------------+-------------------------------------+
85+
86+
Other hardware features are not yet supported in this Zephyr port.
87+
88+
The default configuration can be found in
89+
:zephyr_file:`boards/st/nucleo_f072rb/nucleo_f072rb_defconfig`
90+
91+
Connections and IOs
92+
===================
93+
94+
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
95+
input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the
96+
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current
97+
capable except for analog inputs.

Programming and Debugging
120+
*************************
121+
122+
Nucleo F072RB board includes an ST-LINK/V2-1 embedded debug tool interface.
123+
124+
Applications for the ``nucleo_f072rb`` board configuration can be built and
125+
flashed in the usual way (see :ref:`build_an_application` and
126+
:ref:`application_run` for more details).
127+
128+
Flashing
129+
========
130+
131+
The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
132+
so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
133+
134+
Alternatively, OpenOCD or JLink can also be used to flash the board using
135+
the ``--runner`` (or ``-r``) option:
136+
137+
.. code-block:: console
138+
139+
$ west flash --runner openocd
140+
$ west flash --runner jlink
141+
142+
Flashing an application to Nucleo F072RB
143+
----------------------------------------
144+
145+
Here is an example for the :zephyr:code-sample:`blinky` application.
146+
147+
.. zephyr-app-commands::
148+
:zephyr-app: samples/basic/blinky
149+
:board: nucleo_f072rb
150+
:goals: build flash
151+
152+
You will see the LED blinking every second.
153+
154+
Debugging
155+
=========
156+
157+
You can debug an application in the usual way. Here is an example for the
158+
:zephyr:code-sample:`hello_world` application.
159+
160+
.. zephyr-app-commands::
161+
:zephyr-app: samples/hello_world
162+
:board: nucleo_f072rb
163+
:maybe-skip-config:
164+
:goals: debug
165+
