Hi, I am working on STM32WB55RG MCU and I wanted to enable one pin for Wakeup from Shutdown mode. That works fine. But, when another EXTI pin is initialized, I am not able to disable it. The MCU wakes up when this pin (connector) state is changed, ev...

Hello all, I have a very strange issue with QSPI peripheral. I am using it to store logs in external memory. The flash that is used is MT25QL256ABA with a custom STM32WB55 board. I have connected PModSF3 using jumper wires that are at least 15cm long...

Hello all, Following up on https://community.st.com/t5/stm32cubeide-mcus/usbx-dual-composite-cdc-acm-not-working/td-p/708277, I tried to implement the same Dual CDC-ACM on STM32H723 Nucleo. I have run into the same issues.With just one CDC_ACM class ...

Hello all, I have not been able to get the DFSDM_AudioRecord example to work on STM32H735G-DK.I am using CubeFW v1.11.2 and Cube MX 6.11.1. Furthermore, I tried debugging and noticed that the DMA Callbacks for Half and Full complete are called. Then ...

Hello @TDK, I can confirm that the button is pulled down. The issue that we are facing is being unable to disable the ACOK pin as wake-up source.

Hello @TDK,Thank you for the response. > What is keeping the pin at a known state to prevent noise from triggering it? Has to be a pullup or pulldown somewhere.For the pin we want the device to wake-up, it is connected to a button. For, the pin that ...

@Tesla DeLorean,I can confirm that it was the long jumpers that were causing the issue. The same code works perfectly fine on the custom PCB.
