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...
Hi, I have a STM32F407 board that is running as a full duplex slave. it receives data from a Raspberry Pi configured as a SPI master. Is there a way to receive data from the RPi in a non-blocking mode? One way I could think of was to set the CSN line...

Hello, In my project I need to have MCU that can handle lot's of data and be power efficient when I need to. In first, i was running STM32L562, but it looks like I will need tones more performance to complete many tasks in time.I use DMA alot, for se...
Is there a way to make the RTC continue keeping time while the wakeup timer is enabled? On my end, time freezes whenever the `cr.wute` bit is set.The RTC is listed as frozen in init mode, but It's not in init mode. It could be a shadow register issue...
Hi following a reset by the IWDG, does the SRAM1 or SRAM2 keep their content?Thanks
I'm trying to set up SPI transfer via DMA which is triggered by LPTIM1 on STM32H745IIK6. Unfortunately for some reason, no SPI activity is present regardless of the config register values, which seem to be correct. Here's the LPTIM1 and DMA1 config:A...
The interrupt vector table lists TIM3-TIM7 as having the acronym TIM2.
Hello,I am designing an embedded system with these parts:A Low-Power STM32F091RCT6 microcontrollerEC25 LTE/GPRS moduleA 16 Mbit serial flash (W25Q128JV)After each reset, the microcontroller should check if a new version of firmware is available. If s...
Hi,I'm working with stm32H743zi (Nucleo-144) , I have a device that transmitting data via SPI to my stm32H7, the problem is that the device sending data with a variable length that I have no idea about it and there is no way to receive the length bef...
Hi all,I have a complex system with several STM32H743 processors, 1 Master, 6 Slave processors. The Master sequentially reads data from all Slaves via Interrupt handling. SPI clock speed is 16 MHz, access to data reads (108 Bytes each Read) every 10 ...
