Advanced Features

By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.

STM32F401 Nucleo-64 Board Resources Introduction

The STM32 Nucleo-64 is a development board based on STM32F401RE, which contains a Cortex-M4 core. The maximum main frequency is 84 MHz, and it has a wealth of on-board resources that can take full advantage of the STM32F401RE's chip performance.

The mainly-used on-board resources are shown as follows:

MCU : STM32F401RET6
Main Frequency: 84MHz
Memory: 512KB FLASH , 96KB RAM
Common-used peripherals:
- 3 LEDs: USB communication (LD1), user LED (LD2), power LED (LD3)
- 2 Buttons: USER and RESET
Common-used interface: USB, Arduino Uno, and ST morpho
Debug interface: ST-LINK/V2-1

Execution Instruction

Quickly Get Started

This BSP provides MDK5 and IAR projects for developers. Also support GCC development environment Here's an example of the MDK5 development environment, to introduce how to run the system.

Hardware Connection

Use a Type-A to Mini-B cable to connect the development board to the PC and turn on the power switch. The red LED LD3 (PWR) and LD1 (COM) will lit.

Compile And Download

Double-click the project.uvprojx file, to open the MDK5 project, compile and download the program to the board.

By default, the project uses ST_LINK simulator to download the program, when the ST_LINK connects the board, clicking the download button can download the program to the board.

Running Results

After the program is successfully downloaded, the system runs automatically. Observe the running results of the LED on the development board, the red LD3 and LD1 will lit all the time, green LD2 will flash periodically.

The USB virtual COM port connects to serial port 2 by default, and when the corresponding serial port (115200-8-1-N) is opened in the terminal tool, the output information of RT-Thread can be seen when the device is reset:

Advanced Features

This BSP only enables GPIO and serial port 2 by default. If need more advanced features, you need to configure the BSP with RT-Thread Env tools, as follows:
