Other hardware features are not yet supported in this Zephyr port.
The default configuration can be found in the defconfig file:
``boards/arm/nucleo_g071rb/nucleo_g071rb_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/RX : PC4/PC5
- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
- I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
- I2C2 SCL/SDA : PA11/PA12
- SPI1 NSS/SCK/MISO/MOSI : PB0/PA5/PA6/PA7 (Arduino SPI)
- SPI2 NSS/SCK/MISO/MOSI : PB12/PB13/PB14/PB15
- USER_PB : PC13
- LD4 : PA5
- PWM : PA6
- ADC1 IN0 : PA0
- ADC1 IN1 : PA1
- DAC1_OUT1 : PA4
For mode details please refer to `STM32 Nucleo-64 board User Manual`_.
Programming and Debugging
*************************
Applications for the ``nucleo_g071rb`` 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 G071RB board includes an ST-LINK/V3 embedded debug tool interface.
Flashing an application to Nucleo G071RB
----------------------------------------
Here is an example for the :ref:`blinky-sample` application.
.. zephyr-app-commands::
:zephyr-app: samples/basic/blinky
:board: nucleo_g071rb
: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_g071rb
:maybe-skip-config:
:goals: debug
