STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I'm using an STM32H725 to communicate with an i2c sensor. I'm using the I2C4 bus with the HAL DMA functions. I also enabled the BDMA channels for the rx and tx and respective interrupts. The problem is that the complete rx/tx callbacks are not trigge...
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...
I attended the online STM32H5 workshop on Tuesday last week. We were told that the slides and a code for a free STM32H5 Nucleo board would be emailed to us after the workshop. Almost a week later I have still not received either and email to the ad...
