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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

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...
Hello,My aim is to send (from my nucleo board_F103+FTDI) somes ADC value from DMA.Easy...But i would like a frame like that (Windows Software need it):<STX>ADC1;ADC2;ADC3<ETX><CR><LF>I'm able to send data, no more...uint16_t sensor_B =1234; char str[...
Dear eveyone,I' little confuse..I'm trying to send dat over uart from a nucleo board (F103 + FDTI). If a use "normal"method, it's work great.I mean, i receive "1234567890" WITH a new line.uint8_t start [20]= "1234567890 \n\r"; HAL_UART_Transmit(&huar...
