|
|
The default configuration can be found in the defconfig file:
|
|
``boards/arm/nucleo_g070rb/nucleo_g070rb_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_1 TX/RX : PC4/PC5
|
|
- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)

Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``nucleo_g070rb`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
Nucleo G070RB board includes an ST-LINK/V2-1 embedded debug tool interface.
|
|
|
|
Flashing an application to Nucleo G070RB
|
|
----------------------------------------
|
|
|
|
Here is an example for the :zephyr:code-sample:`blinky` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/basic/blinky
|
|
:board: nucleo_g070rb
|
|
: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
|
|
:ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: nucleo_g070rb
|
|
