![]() ![]() Beneath the Nucleo board is the SD card socket. Overview of the breakout board with USB connector. You can also use the FATFS to access the SD card. the meaning of nucleo-txxxry codification is as follows: txxx describes the stm32 mcu product line (t for f or l) r describes the pin count (r for 64 pins) y describes the code size (8 for 64k, b for 128k, c for 256k, e for 512k, g for 1mb, z for 192k) the last six characters (e.g. ![]() That is, if you connect a USB flash drive, you can access its contents using the FATFS library. The code also works as a HOST for Mass Storage Devices. That is, in DEVICE mode, your Nucleo will become a generic USB storage device when connected to the USB port of your computer. So, this post is about of programming a Nucleo-F401RE board to use the STM32F401RE USB peripheral as a DEVICE Mass Storage Class with SDCARD (connected with 4bit SDIO interface) as the media. Most of the codes you will find spread in other examples and libraries. From the Hardware board list, select any other Nucleo board, and click OK. To configure these models for other supported Nucleo boards, browse to Simulation > Model Configuration Parameters > Hardware Implementation on the Simulink® model toolbar. interrupt support USB 12 Mbps Operating power USB OTG FS - Host/Save. These models are pre-configured for STMicroelectronics Nucleo F401RE board. I believe that (at least these days) you will not find another internet site with all the stuff I'm posting here in one place. 2.4 Introduction to Nucleo F401RE Board The reason for choosing the. This post is a result of several hours of hard work, thinking, planning, trial-and-error, debugging, and searching the internet for working code in order to make the USB peripheral of a STM32 act as an USB device (mass storage) and HOST (mass storage too). ![]() interfaces from the host PC, install the Nucleo USB driver available from the webpage. The demo code is hosted at my GitHub account: Arduino connectors on NUCLEO-F401RE and NUCLEO-F411RE Table 17. Serial used is USART2 that is connected in STLINK V2-1 and becomes a Virtual Serial Com port when STLINK is connected. Using a mutex to avoid conflicts with two tasks sharing the serial. NUCLEO-F401RE, ST, STM32 Nucleo-64 development board with STM32F401RE MCU. When the user press the button a string is printed in serial. USB 2.0 full-speed device/host/OTG controller with on-chip PHY USB 2.0. The second task is used to handle the user button switch press event. One of them flashes the LED and prints a string with a counter in serial every second. I creaded a small demo for testing the BRTOS (Brazilian Real-Time Operating System) in my Nucleo board with Coocox COIDE and ARM GCC.īRTOS is a lightweight preemptive real time operating system designed for low end microcontrollers.Ĭheck more info about clock config for NucleoF401 in this post.įlash Prefetch enabled and 2 wait states (minimum for 84MHz and 3.3V). ![]()
