Stm32f446 spdif rx wait for activity - no effect.
HiI configured spdif rx with dma in circular mode and it works fine except that the signal should persist when mcu starts. The "wait for activity before synchronization" has no effect. The code for spdif mostly generated by cubeIDE.Am i missing somet...
Resolved! Unable to use SMPS on STM32U375CGUxQ
I'm currently trying to configure a project based on an STM32U375CGUxQ, but I can only "choose" the LDO, even though the package clearly shows the SMPS pins:I'm using the STM32U3 package version 1.2.0, STM32CubeIDE 1.19.0, build 25607_20250703_0907. ...
Check SWV ITM trace from code
Hello,I am using the STM32F767ZI MCU and was wondering if it is possible to check if a debugger is connected or not and if SWV is enabled, to avoid the UN-necessary looping when a printf is encountered.These are my requirements:Check if the user has ...
ST67W611M and STM32H7A3ZIT6 schematic + PCB review
We are designing a benchtop device with an LCD, battery, and wireless capabilities and have chosen the STM32H7A3ZIT6 MCU and ST67W611M WiFi/BT SoC. It's intended to use TouchGFX for the graphics. The board is complete and ready to order but I'd like ...

Dear all,I'm currently trying to work with USART1 on my Nucleo-N6 board.Here's how I attempted to initialize the board:CPU Frequency: 600 MHzPeripheral Bus (PB1, PB2, PB4, PB5): 50 MHzGPIO Configuration:PE5: Alternate function, push-pull — USART1_TX ...
Resolved! STM32H7 NUCLEO-H723ZG SPI Master RXONLY mode - how to remove 10us SCK delay?
Hello,I am using an STM32H7 MCU with STM32CubeIDE to communicate with a BiSS-C encoder in SPI RXONLY Master mode.My goal is to generate 64 SCK clocks every 10ms without delay.However, I am observing the following issue: Each time I call HAL_SPI_Recei...
2 BLE devices but showing one in BLE mobile apps
Hello everyone,I’m using two STM32 MCU on baord with (BlueNRG-MS) stacked within, each running the same firmware that have BD_ADDR . When I power both boards on, I expect to see two separate entries in scanner apps like LightBlue or nRF Connect—but ...
STM32N657 (Nucleo-N657X0) Core is locked up.
I followed the steps in this demo workshop to upload a simple program to toggle LEDs to the Nucleo-N657X0 board. The project is in FSBL. I can run the code in debug mode and upload the signed program to the external flash on the Nucleo-N657X0 board w...
