Nucleo F411RE

Overview

The Nucleo F411RE board features an ARM Cortex-M4 based STM32F411RE MCU with a wide range of connectivity support and configurations. Here are some highlights of the Nucleo F411RE board:

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
On-board ST-LINK/V2-1 debugger/programmer with SWD connector
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

Connections and IOs

Nucleo F411RE Board has 8 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.

Available pins:

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

Default Zephyr Peripheral Mapping:

UART_1 TX/RX : PB6/PB7
UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
I2C2 SCL/SDA : PB10/PB3
I2C1 SCL/SDA : PA8/B4
SPI1 CS/SCK/MISO/MOSI : PA4/PA5/PA6/PA7 (Arduino SPI)
I2S1 SCK/SD : PA5/PA7 (Arduino I2S)
USER_PB : PC13
LD2 : PA5

Note

Please note that SPI1 and I2S1 are connected to the same mcu pins, as the h/w controller is the same one.

System Clock

Nucleo F411RE System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 84MHz, driven by 8MHz high speed external clock.

Serial Port

Nucleo F411RE board has 3 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1.

Programming and Debugging

The nucleo_f411re board supports the runners and associated west commands listed below.

	flash	debug

Nucleo F411RE board includes an ST-LINK/V2-1 embedded debug tool interface.

Applications for the nucleo_f411re 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 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 F411RE

Here is an example for the Hello World application.

Run a serial host program to connect with your Nucleo board.

$ minicom -D /dev/ttyACM0

Build and flash the application:

# From the root of the zephyr repository
west build -b nucleo_f411re samples/hello_world
west flash

You should see the following message on the console:

$ Hello World! arm

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b nucleo_f411re samples/hello_world
west debug
