System Clock
|
|
============
|
|
|
|
STM32F3DISCOVERY System Clock could be driven by internal or external
|
|
oscillator, as well as main PLL clock. By default System clock is driven
|
|
by PLL clock at 72 MHz, driven by 8 MHz MCO from the ST Link.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
STM32F3DISCOVERY Discovery kit has up to 5 UARTs. The Zephyr console output
|
|
is assigned to UART1. Default settings are 115200 8N1.
|
|
|
|
I2C
|
|
===
|
|
|
|
STM32F3DISCOVERY has up to 2 I2Cs. I2C1 is connected to the LSM303DLHC and is
|
|
an ultra-compact low-power system-in-package featuring a 3D digital linear
|
|
acceleration sensor and a 3D digital magnetic sensor.
|
|
|
|
USB
|
|
===
|
|
STM32F3DISCOVERY has a USB 2.0 full-speed device interface available through
|
|
its mini USB connector (USB USER).
|
|
|
|
CAN
|
|
===
|
|
The STM32F3DISCOVERY does not have an onboard CAN transceiver. In
|
|
order to use the CAN bus on the this board, an external CAN bus
|
|
transceiver must be connected to ``PD0`` (``CAN1_RX``) and ``PD1``
|
|
(``CAN1_TX``).
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Flashing
|
|
========
|
|
|
|
STM32F3DISCOVERY Discovery kit includes a ST-LINK/V2 or ST-LINK/V2-B embedded
|
|
debug tool interface.
|
|
|
|
Applications for the ``stm32f3_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 an application to STM32F3DISCOVERY
|
|
-------------------------------------------
|
|
|
|
First, connect the STM32F3DISCOVERY Discovery kit to your host computer using
|
|
the USB port to prepare it for flashing. Then build and flash your application.
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32f3_disco
|
|
:goals: build flash
|
|
|
|
|
|
In case you are using a recent PCB revision (E or newer), you have to use an
|
|
adapted board definition:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32f3_disco@E
|
|
:goals: build flash
|
|
|
|
Run a serial host program to connect with your board. For PCB version A or B a
|
|
TTL(3.3V) serial adapter is required. For PCB version C and newer a Virtual Com
|
|
Port (VCP) is available on the USB ST-LINK port.
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/<tty device>
|
|
|
|
Replace <tty_device> with the port where the STM32F3DISCOVERY board can be
|
|
found. For example, under Linux, /dev/ttyUSB0.
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
Hello World! arm
|
|
|
|
|
|
Debugging
|
|
=========
|
|
|
|
You can debug an application in the usual way. Here is an example for the
|
|
:ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32f3_disco
|
|
:goals: debug
|
|
|
|
Again you have to use the adapted command for newer PCB revisions (E and newer):
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32f3_disco@E
|
|
:goals: debug
