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...
Hello,We are using the STM32H745 dual-core MCU for a mostly-analog sensor project. The M4 core is running at 240 MHz and generating a signal on the fly that is passed to the DAC via a DMA stream in circular buffer mode. This part works great.The si...
Is there any part from STM which able to operates as bluetooth HID keyboard as well as bluetooth touchpad?
Hi :) So I keep reading everywhere that leaving a CMOS input pin floating is bad because it is high impedance, can oscillate, etc. I understand and agree.But while a MCU is starting up (or when you're programming it) all its pin are in input state un...
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.
