USB Device HUB class on f103

Is it possible to implement device HUB?(i want my f103 to appear as usb HUB to host PC)Like a compound device. Cant find any example for some reason.

How to Configure LWIP + FreeRTOS in STM32CUBE 6.1 ( STM32H750 + LAN8720 ) ?

Hi,I tried to run lwip and freertos on stm32h750 with physical ic lan8720. Unfortunately, the program hangs inside the MX_LWIP_INIT() function and I don't have ping.Other threads do not work either and all codes inside the main function before the MX...

STM32 USB Audio Device (microphone) with 24-bit resolution

As far as I know, STM32Cube does not offer support for creating an USB microphone (only speaker, as stated in the specification). However, I have managed to use the X-CUBE-MEMSMIC1 package to create an audio device, only replacing the usbd_audio.c an...

What is needed to develop an IOT device using STM32 specifically utilising ethernet?

Hi,I'm hoping this is the correct forum to ask this question. I am developing an industrial product using STM32 devices and I need to add ethernet capability to the product. I have a moderate amount of embedded development experience but zero network...

Resolved! What's the best way to port CMSIS UART from F0 to G0

An existing project runs on STM32F091, it use CMSIS USART driver (ARM_DRIVER_USART Driver_USART1). Now I need to migrate this project to run on STM32G070. But in CubeMX for STM32G070, there aren't any USART driver under CMSIS driver, except a header ...

SPI DMA in slave mode , HAL_SPI_TxRxCpltCallback() callback not being called?

I am using STM32F446RET6 with STM32CubeMX and STM32CubeIDE to create an SPI slave device using SPI1 in DMA mode using the HAL SPI driver. I call HAL_SPI_Receive_DMA() in main to receive 1 byte from the attached SPI master device. It is successful, an...
