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 All, We are using STM32F746 MCU with external Memory. We use internal flash for bootloader image and our main image is on QSPI memory. We read something about STM32F7 HW issues for example to access QSPI using DMA, Cache's need to be disabled. On ...
I've got a problem with stm32f407zet . I use also LL drivers and 3 ADCs with dma .No problem when run separately , e.g. only ADC 1 - results are corrects , only ADC3 - results are corrects .Problem is when I turn on two ADC by ://adc1 LL_ADC_C...

Hello! I try to make SDIO 4 wide bus and USB Host MSC class works together. I want to write data to microSD card and copy that files to USB stick. It works separately. When i configure SDIO but not configure USB in CubeMX, data writes to SD-card. Whe...
Posted on June 07, 2018 at 17:51I'm using an STM32F723 with a customised USB driver to capture Isochronous data.I can capture the data in 4KiB chunks. The data is DMA'd into internal SRAM then modified and copied to internal SRAM then DMA'd to an SD...
try to run the example USB_DEVICE\MSC_Standalone in FW_L4_V1.12.0. it seems to have a conflict with the MSC in st-link. changed to j-link without msc, the example runs but it last serveral minutes until the drive letter apperas on PC after plugt in t...
Posted on April 04, 2017 at 17:15 Dear ST support team, I found minor bug on CubeF7 v1.6.0. Bug found at ./STM32Cube_FW_F7_V1.6.0/Projects/STM32746G-Discovery/Applications/USB_Device/MSC_Standalone/Src/usbd_storage.c diff -urN b/usbd_stor...
We have a STM32F091 MCU board, it works, but we require to add bootloader function in for field update firmware.The BOOT0(PF11) is connect to GND via 10K resistor, so it will go to Flash Memory after power up, it does that (LED flash).I connect BOOT0...
Hi I am designing an application where the STM32L4 is connected to a PCs USB port. The board is always powered up by an external supply input, and not the PCs USB. Can anyone tell me if I have to use the VDDUSB pin on the STM32? I dont have to power ...
Hi. I'm not sure is it a right place - my problem is more like an issue. I've downloaded STM32CubeF1 from here: https://my.st.com/content/my_st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-mcu-packages/st...
