Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I have an issue where a HAL_I2C_Mem_Read_IT transaction just seems to hang. It is plausible that this peripheral is temporarily unavailable and I already have working retry logic for the case where this call returns the "AF" error. The hang may or ...
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...
The STM32H750B-dk Based Custom Board isn't entering debugging mode when using STM32CubeIDE . But QSPI Example Code is working perfectly.
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...
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?
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...
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...
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...
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....
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...
