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.
Board connectors:
Default Zephyr Peripheral Mapping:
UART_1 TX/RX : PA2/PA15 (ST-Link Virtual COM Port)
I2C1 SCL/SDA : PB6/PB7 (Arduino I2C)
SPI1 NSS/SCK/MISO/MOSI : PA4/PA5/PA6/PA7 (Arduino SPI)
LD2 : PB3
For more details please refer to STM32 Nucleo-32 board User Manual [4].
Programming and Debugging
Nucleo F031K6 board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the nucleo_f031k6 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 [5] runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to Nucleo F030R8
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b nucleo_f031k6 samples/basic/blinky
west 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 Blinky application.
# From the root of the zephyr repository
west build -b nucleo_f031k6 samples/basic/blinky
west debug
