Resolved! USBX Device MSC in Standalone mode
I'm trying to get USBX Device MSC to work in Standalone mode (without RTOS). I loosely followed @B.Montanari 's example in https://community.st.com/t5/stm32-mcus/how-to-implement-usbx-in-standalone-mode/ta-p/614435, and also referred to a CubeMX exa...
Possible to combine two SPI flash chips into "one" larger memory?
Hi,I would like to implement a USB -> SPI flash storage solution. There are several guides and examples already available to do so (also the tinyUSB ones), so I think that should not be an issue.However, due to physical constraints of my project, I d...
Aborting an HAL_I2C_Mem_Read_IT or HAL_I2C_Mem_Write_IT
Hello, I am looking at how to abort the MemX_IT functions. Looking through HAL_I2C_Master_Abort_IT, it seems like that only works for the Master API functions and not the mem functions. Are there any HAL functions for Mem Abort?
STM32F4: Continuous DMA won't iterate, stuck on first SPI command
I'm working on a DMA routine for my SPI DAC, and I've loaded up a buffer with the commands to make a sine wave. But when I check it with the oscilloscope, it's just stuck at 2.05V, which is actually the very first command in my sequence.I've spent ho...
Ethernet problem on STM32H747I-DISCO board
Hi everyone,I have a problem with the Ethernet connection that I can't solve on the STM32H747I-DISCO board.I followed Adam Berlinger's guide step by step (https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lw...
STM32N6570-DK Ux_Host_VIDEO example not working with UVC cameras (e.g. Logitech C270)
Hello,I'm trying to run the Ux_Host_VIDEO example from STM32CubeN6 on the STM32N6570-DK board, but UVC camera streaming does not work. The USB device is detected, but no video stream starts. Test Environment:Board: STM32N6570-DKExample: Ux_Host_VIDEO...
STM32F7 problem with ETH on high UDP load
Hello everyone. I'm developing Ethernet on NuceloF746ZG board. I'm listening to the UDP on port 1001,where there is datagram incoming every 2ms, but my callback function gets called 96 times, before it stops, and resumes for next 96 times, and so on....
Bidirectional Communication Between CM4 and CM7 Not Working on STM32H747I-DISCO (FreeRTOS Stream Buffer / Core Message Buffer)
Working on bidirectional communication between CM4 and CM7 on the STM32H747I-DISCO using FreeRTOS stream buffers (CoreMessageBuffer). One-way communication works fine (either CM4 → CM7 or CM7 → CM4), but both directions at the same time do not work...
STM32N6570-DK USB UVC Not Detected – Possible USBPD/UCPD Dependency?
Hello,I'm working on implementing USB UVC on the STM32N6570-DK board. I generated a project using STM32CubeMX only for FSBL and added the following files manually from the ST USBX example project1 . ux_device_video.c and .h2 . ux_device_descriptors ....
