.. zephyr:board:: nucleo_c092rc

Overview

The STM32 Nucleo-64 development board, featuring the STM32C092RC MCU, supports both Arduino and ST morpho connectivity, and includes a CAN FD interface with an onboard transceiver.

More information about the board can be found at the Nucleo C092RC website_.

Hardware

Nucleo C092RC provides the following hardware components:

STM32 microcontroller in 64-pin package featuring 256 Kbytes of Flash memory and 30 Kbytes of SRAM.
Flexible board power supply:
- USB VBUS or external source (3.3V, 5V, 7 - 12V)
- Current consumption measurement (IDD)
Five LEDs:
- Two user LEDs (LD1, LD2), one power LED (LD3), one STLINK LED (LD4), and one USB power fault LED (LD5)
Three push-buttons: USER, RESET, BOOT
On-board ST-LINK/V2-1 debugger/programmer with SWD connector
Board connectors:
- Arduino* Uno V3 expansion connector
- ST morpho extension pin header
- CAN FD interface with on-board transceiver

Supported Features

.. zephyr:board-supported-hw::

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:

CAN RX/TX/STBY: PD0/PD1/PD2
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
LD1 : PA5
LD2 : PC9
SPI1 NSS/SCK/MISO/MOSI : PA15/PA5/PA6/PA7 (Arduino SPI)
UART_1 TX/RX : PB6/PB7 (Arduino Serial)
UART_2 TX/RX : PA2/PA3 (ST-Link Virtual COM Port)
USER_PB : PC13

For more details please refer to STM32 Nucleo-64 board User Manual_.

Programming and Debugging

.. zephyr:board-supported-runners::

Nucleo C092RC board includes an ST-LINK/V2-1 embedded debug tool interface.

Applications for the nucleo_c092rc board can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details).

Flashing

The board is configured to be flashed using west STM32CubeProgrammer_ runner, so its :ref:installation <stm32cubeprog-flash-host-tools> is required.

Alternatively, an external JLink (Software and Documentation Package Version >= v8.12e) can also be used to flash the board using the --runner option:

.. code-block:: console

$ west flash --runner jlink

Flashing an application to Nucleo C092RC

Here is an example for the :zephyr:code-sample:blinky application.

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: nucleo_c092rc :goals: build flash

You will see the LED blinking every second.
