Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi,The project was created in stm32mx from the example project cortexm_sysk.It was generated as a CMake project and developed using VS Code.The "USB Device Middleware Library MCU Software Component" library, version "V2.11.4 / 11-April-2025", was man...
Hello All,On the STM32U575 is there any guidance regarding use of external resistors? I don't see any on the reference design so I didn't put it on my board either. USB data rates are fairly slow, is impedance matching even required?We are using Ti...
I am experiencing an issue with ADC3 multi-channel scan mode on a custom STM32H745 board (LDO power supply). The same code works perfectly on the Nucleo-H745ZI reference board (SMPS power supply), but fails on my custom design. Problem Summary: ADC3 ...
Hi everyone,I'm working on a project based on the following STM32H7 LwIP example:https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H747_Disco_M7_ETHIn addition to the Ethernet functionality, I’ve enabled the SAI peripheral with DM...
There is a bug in the FW package V1.6.3 where the UART and DMA doesn't work correctly.I've been using FW package V1.6.2 for awhile with UART in DMA circular mode and it has never had an issue. I've recently made a copy of the project to make an A and...
I was wondering what is that. I created a custom bootloader firmware and application firmware. But once I successfully uploaded. When I send application firmware resquest I do not receive application firmware responses. Why is that? what is that? do ...
Hi everyone,I am working on a project using the STM32H753ZI Nucleo-144 board. My goal is to save data to an external USB thumb drive via the CN13 (USB OTG FS) port.My Environment:RTOS Stack: ThreadX, NetXDuo (Ethernet is working), USBX (Host/Storage...
Hi Everyone,We are developing a Sub-GHz/LoRa device based on STM32WLE5CCU6 and have encountered an issue relatedto the Sub-GHz Radio BUSY state. We would like to ask for possible root causes and the recommendedrecovery procedure.The observed behavior...
