STM32 MCUs Embedded software

how many uarts in STM32H7B3I-DK is it disponible to use? And if i use the wifi module, can i use the usb as a host?

Can I write to 2 different ports using two pcbs? (LWIP, raw API) It seems to only write to 1 twice?

I'm trying to provide a server connection to 2 clients on ports 1024 and 1025 using LWIP raw API. I have created two separate pcbs and can listen on both ports successfully, but writing to either pcb results in data being sent to the first pcb only;/...

stm32f439 ethernet reference design with LAN8742A

Do we have any reference firmware and hardware design for stm32f439 and LAN8742A possibly using FreeRTOS in the design example.

Hi i have an Nucleo-L073RZ eval board need to implement sd card +spi + fatfs on it, i have attached a microsd card slot to the eval board , using Sd card 16GB SDHC . I have referred many projects from online for STM32F0 board .

It does not work on my eval board not even able to mount the sd card. Is their any restriction or limit wrt to clock for implementing this since stm32f0 can have max 0f 72MHz wheras stm32l0 only 32Mhz. if so how can this limitation be overcome . ...

AUDIO RECORD - MEMS > DFSDM > I2S > FATFS > Ethernet

Hello everyone,I'm trying to implement an audio acquisition system based on some demos from ST's CubeHAL libs. I'm using the STM32F413-Discovery board as a target for this project. It has most of the peripherals needed to complete the job, LCD, MEMS,...

Guide to use USB device mode in NUCLEO STM32H745ZI-Q

Hello everyone !I'm starting with this h7 family but I wasn't able to get any usb example for the nucleo stm32h745. So I've been using the discovery board ones.But It didn't work , the usb state got suspended and the pc is warning a unknown device .I...

X-CUBE-USB-PD problem, stopped responding to anything after I unplugged the cable.

The X-CUBE-USB-PD is running on my custom PCB with the STM32F072CB and FUSB307B. That project is based on the sample project, EVAL_FUSB307B_DRP, which works as a DRP.When I have traces functioning at build time and the system is acting as a source, i...

Hi, I'am trying to connect two STM32H7 boards with ethernet protocol, I want to exchange some UDP messages, I implemented code for udp protocol but it still not working. Is there any example of two boards connection through ETH lwip .Thanks for help

FATFS + FreeRTOS memory corruption, need confirmation

Hi,I created a project using the STM32CubeIDE for a STM32F2xx. This project include USB in host mode with a mass storage class, FATFS and FreeRTOS.With freeRTOS, FATFS is put in REETRANT mode. I also put the MAX_SS to 4096 because I need the sector s...
