Something went wrong when I tried to order the NUCLEO-H563ZI in connection with the " STM32H5: Ultimate combination of performance, integration and affordability" workshop. Now the system has not accepted my order but also says that I have used the c...
I have a STEVAL-STWINBX1 (released a few weeks ago). It sports a STM32U585AI MCU.The Android app fails to connect to the device. An iPhone app connected but was never able to upgrade its firmware or turn on/off data logging.I found is repository that...
Hello,We are using STM32F765BI series MCU. We are using SD Card using the SDIO interface. It seems that when the SDIO module is Active (CLK signal is generated at 24MHz), higher emissions are observed in the spectrum. When we disable the SDIO module ...

Hi Everyone. My EV Board use 24 MHz HSE but I used PLL to get with 170 MHz, I also set this frequency for the clock of timer module. I could get 2us periodic signal normal from timer setting however I cannot get 1us periodic signal normally (you can...
Hello,I would like to receive the UL(E480533) condition of acceptability what is the failures in the internal watchdog? is external watchdog is needed ?Do you have risk assessment for STM32F ? can you share it?can you recommend a consulting company t...
I have a very odd problem. I am using the STM32G473 and have configured the clock to 170MHz. When the code runs it drops to default_handler every time after setting up the clock. Not unusual if there is no ISR or call back set up. However if i set th...
EDIT: Hello, everyone. My code issue seems to have resolved itself after much changing, but I never did find out what was happening. My real question was answered: There are no likely circumstances that a higher-priority interrupt should not pre-e...
Hi, All. I have come across an odd situation in I2C communication between F405 and sensors1) F405 is master. address is 7 Bit2) with 3 slave I2C sensors , address, 22h,35h,78h3) There is no issue to read data from sensors of 22h and 35hbut when comm...
