USBH_AUDIO_InputStream() missing — how to stream USB microphone data on STM32?
Hello,I'm working on a project using the STM32F401RE board to perform real-time fault diagnosis on machinery.The board receives vibration data in real-time via a USB-type accelerometer (Digiducer 333D01), and a lightweight deep learning model running...
Keil "INTERNAL PARAMETER ERROR" Programming STM32H7 CM4 Core
I am working on programming a custom-designed board featuring the STM32H747IGT6 MCU using the Keil MDK-ARM environment. While I can successfully program and debug the Cortex-M7 (CM7) core, I encounter an "INTERNAL PARAMETER ERROR" when attempting to ...
STM32H743 ETH Problem with RT Thread and LWIP
Hi,I created the STM32H743 project based on RT Thread and LWIP, only open ICache, if I modify the content of a function, it will lead to the Ethernet transmission success, but there is no data on the MII interface, debugging compared the ETH register...

Classic USB printer
Hi everyone,I'm currently working on a project to turn an STM32 microcontroller into a USB printerdevice. I have spent a considerable amount of time searching for a comprehensive guideor a complete implementation for the classic USB printer device cl...
Resolved! Driving DAC too fast
I've got an STM32G491RE on a NUCLEO-G491RE board and I'm driving the DAC using TIM4's TRGO and pulling values out of a memory buffer using DMA. It was a bit of a challenge getting set up, but now that it's running it's beautiful.What's weird is that...
STM32N6 VENC_RTSP_SERVER at lower resolutions
Hi everyone,I am currently working on the VENC_RTSP_SERVER example. I have successfully run it and captured video using ffplay. However, it is recording at 960x720 @ 20fps. I am trying to reduce the resolution to 480x480.To do this, I modified the MX...
Resolved! SPI Communication with Peripherals in Different Modes (Mode 0 & Mode 1)
Good afternoon Team,I am working on a project where I need to interface two SPI peripherals with an ST microcontroller (STM32G070RBT6).One peripheral (ADS124S06) operates in SPI Mode 1 (CPOL=0, CPHA=1), and the other (64128L FC BW-RGB Display) in SPI...
