ST Nucleo F030R8¶
The STM32 Nucleo-64 development board with STM32F030R8 MCU, supports Arduino and ST morpho connectivity.
The STM32 Nucleo board provides an affordable, and flexible way for users to try out new concepts, and build prototypes with the STM32 microcontroller, choosing from the various combinations of performance, power consumption and features.
The Arduino* Uno V3 connectivity support and the ST morpho headers allow easy functionality expansion of the STM32 Nucleo open development platform with a wide choice of specialized shields.
The STM32 Nucleo board integrates the ST-LINK/V2-1 debugger and programmer.
The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples.
Nucleo F030R8 provides the following hardware components:
- STM32 microcontroller in QFP64 package
- Two types of extension resources:
- Arduino* Uno V3 connectivity
- ST morpho extension pin headers for full access to all STM32 I/Os
- ARM* mbed*
- On-board ST-LINK/V2-1 debugger/programmer with SWD connector:
- Selection-mode switch to use the kit as a standalone ST-LINK/V2-1
- Flexible board power supply:
- USB VBUS or external source (3.3V, 5V, 7 - 12V)
- Power management access point
- Three LEDs:
- USB communication (LD1), user LED (LD2), power LED (LD3)
- Two push-buttons: USER and RESET
- USB re-enumeration capability. Three different interfaces supported on USB:
- Virtual COM port
- Mass storage
- Debug port
- Support of wide choice of Integrated Development Environments (IDEs) including:
- ARM Keil
- GCC-based IDEs
The Zephyr nucleo_f030r8 board configuration supports the following hardware features:
|NVIC||on-chip||nested vector interrupt controller|
|UART||on-chip||serial port-polling; serial port-interrupt|
|CLOCK||on-chip||reset and clock control|
Other hardware features are not yet supported in this Zephyr port.
The default configuration can be found in the defconfig file:
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 : PA9/PA10
- UART_2 TX/RX : PA2/PA3 (ST-Link Virtual COM Port)
- I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
- I2C2 SCL/SDA : PA11/PA12
- SPI1 NSS/SCK/MISO/MOSI : PA4/PA5/PA6/PA7 (Arduino SPI)
- SPI2 NSS/SCK/MISO/MOSI : PB12/PB13/PB14/PB15
- USER_PB : PC13
- LD1 : PA5
Programming and Debugging¶
Nucleo F030R8 board includes an ST-LINK/V2-1 embedded debug tool interface. This interface is supported by the openocd version included in the Zephyr SDK.
Flashing an application to Nucleo F030R8¶
Here is an example for the Blinky Application application.
# On Linux/macOS cd $ZEPHYR_BASE/samples/basic/blinky mkdir build && cd build # On Windows cd %ZEPHYR_BASE%\samples\basic\blinky mkdir build & cd build # Use cmake to configure a Ninja-based build system: cmake -GNinja -DBOARD=nucleo_f030r8 .. # Now run ninja on the generated build system: ninja ninja flash
You will see the LED blinking every second.
You can debug an application in the usual way. Here is an example for the Blinky Application application.
# On Linux/macOS cd $ZEPHYR_BASE/samples/basic/blinky # If you already made a build directory (build) and ran cmake, just 'cd build' instead. mkdir build && cd build # On Windows cd %ZEPHYR_BASE%\samples\basic\blinky # If you already made a build directory (build) and ran cmake, just 'cd build' instead. mkdir build & cd build # Use cmake to configure a Ninja-based build system: cmake -GNinja -DBOARD=nucleo_f030r8 .. # Now run ninja on the generated build system: ninja debug
