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, I'm using Cube and Makefile.I'd like a clearer run through of how to make use of the sqrt f32 function in arm_math.h.. The header doco says to copy the header to Include, done.. Then link the Lib for big/little endian. Here's where I'm stuck, how...

Hello everyone, im currently studying DMA on STM boards, and im trying to send I2C messages from a mcu SLAVE (arduino) to STM32F407VET6 master, but both SCL and SDA lines is held low, it doesn´t happen when im using I2C in polling or interrupt mode, ...
Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...
Trying to receive data on MCU (L432KC) configured as SPI slave. I have tried using interrupt and DMA, but no luck. I have set up the circuit like this : 1 MCU acts as master sending 1,2,3 every 500ms interval (I hooked up master lines to scope and th...
I'm using an STM32F407 MCU with a 600 PPR incremental optical encoder. The encoder is coupled to a stepper motor that drives a 5mm pitch ballscrew. I'm trying to keep track of the encoder count to determine the absolute position of the spindle attach...
In STM32F7 dual/single bank configuration is available. It can be done using nDBANK bit of FLASH_OPTCR register. Ref link: https://www.st.com/resource/en/application_note/dm00266999-stm32f7-series-flash-memory-dual-bank-mode-stmicroelectronics.pdfFor...
Hello guys.Eventually I have to learn how to use CMSIS my self to create my own code instead of using CUBE.There was alot of examples for everything in CUBE,but I cant find examples written in CMSIS.Can someone help me finding them?The other question...
Hi, Im a newbie to ZEPHR and would like to test the ADC feature, I just want to be able to read the voltage level on an I/O pin. I have been unable to find sample code. Any help would be appreciated.
