Overview of the breakout board with USB connector. You can also use the FATFS to access the SD card. That is, if you connect a USB flash drive, you can access its contents using the FATFS library. Itrsquo s the next member of the X-NUCLEO ARM® Cortex®-M4 32b MCU+FPU, 105 DMIPS, 512KB Flash/96KB RAM, 11 TIMs, 1 ADC, 11 comm. It is designed for easy evaluation and proof of concept.

The code also works as a HOST for Mass Storage Devices. NUCLEO-F401RE STMicroelectronics X-NUCLEO-IHM15A1 dual brush DC motor driver expansion board is based on the STSPIN840. 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. OLED General Multi Color LCD Raspberry Pi LCD Arduino LCD Mono Color LCD Cameras. USB to UART / FIFO Ethernet Ethernet to UART RS232 / RS485 / CAN OLEDs / LCDs. Most of the codes you will find spread in other examples and libraries. NUCLEO-F401RE, Development board for STM32 F4 series - with STM32F401RE MCU, supports Arduino. 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. USB CDC/ACM device the host computer will delay a little bit to enumerate. 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). I flashed nuttx nuttx on nucleo f401re board but nuttshell is not connecting. The demo code is hosted at my GitHub account:

Serial used is USART2 that is connected in STLINK V2-1 and becomes a Virtual Serial Com port when STLINK is connected. In this case the USB peripheral behaves as as USB HOST.

Using a mutex to avoid conflicts with two tasks sharing the serial. You can also use it to read contents of a flash drive (thumb drive) connected to USB interface of the STM32F401RE. When the user press the button a string is printed in serial. Microcontroller: STM32F401RET6 ARM®32-bit Cortex®-M4 CPU Operating Voltage: 3. 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). selected (NUCLEO STM32F401RE), the compiler must be opened and the selected MBED enabled device will appear as one of the devices belonging to the user.
