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_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
LD4 : PA5
For more details please refer to STM32 Nucleo-64 board User Manual [3].
Programming and Debugging
Nucleo C031C6 board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the nucleo_c031c6 board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer [4] runner, so its installation is required.
Flashing an application to Nucleo C031C6
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_c031c6 samples/basic/blinky
west flash
You will see the LED blinking every second.
