ST STM3210C Evaluation
######################

Overview
********
The STM3210C-EVAL evaluation board is a complete development platform for STMicroelectronic's
ARM Cortex-M3 core-based STM32F107VCT microcontroller.

The range of hardware features on the board help you to evaluate all peripherals
(USB-OTG FS, ethernet, motor control, CAN, microSD CardTM, smartcard, USART,
audio DAC, MEMS, EEPROM and more) and develop your own applications.

Extension headers make it easy to connect a daughterboard or wrapping board for your specific
application.

Supported Features
==================

The Zephyr stm3210c_eval 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/stm3210c_eval/stm3210c_eval_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.

- UART_2_RX : PD6
- USER_PB   : PB9
- LED2      : PD13

Programming and Debugging
*************************

Flashing
========

STM3210C-EVAL board includes an ST-LINK/V2-1 embedded debug tool interface.
At power-on, the board is in firmware-upgrade mode (also called DFU for
"Device Firmware Upgrade"), allowing the firmware to be updated through the USB.
This interface is supported by the openocd version included in Zephyr SDK.

Applications for the ``stm3210c_eval`` 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 STM3210C-EVAL
----------------------------------------

Connect the STM3210C-EVAL to your host computer using the USB port, then build
and flash 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: stm3210c_eval
   :goals: build flash

You will see the LED blinking every second.

Debugging
=========

You can run a serial host program to connect with your STM3210C-EVAL board. For
example, on Linux:

.. code-block:: console

   $ minicom -D /dev/ttyACM0

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: stm3210c_eval
   :maybe-skip-config:
   :goals: debug
