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 am trying to add two virtual COM ports on STM32WB5MMHGx device. The initial code is based out of STM32Cube example: Ux_Device_CDC_ACM. I initially added this piece of code to register the class. cdc_acm_parameter2.ux_slave_clas...

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 ...

@Tesla DeLorean Thank you for the reply! @Tesla DeLorean wrote:That does seem excessively long, the fixtures I've built are at least half that length, and wire-wrapped, not sketchy dupont wiring. For push fit connections perhaps look at Schmart jumpe...

Another strange thing that I have observed when using Quad (1-1-4) addressing is that, when I write the same byte, the contents are perfectly read back.stm32wb>qspi.flash.validate 0x00 256 | CONSOLE | QSPI flash sector erased at address 0x00000000 ...

Hi @Tesla DeLorean,Thank you for the reply!This external flash also has a 3-byte addressing mode too. With which the upper or lower 128Mb can be used based on the configuration in volatile registers. I have interfaced this flash in SPI mode, it works...
