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...

Hello,I've designed a board based on an STM32F091CBU.I needed CAN bus support, one SPI and one I2C and a timer interrupt.When I tested my program, it hanged during the initialization of the IMU (an LSM6DSM) due to HAL_delays I ordinary set between SP...
Hi,1.Wanted to know does the execution time reduces(speed increases). If text segment is brought to SRAM from flash at start up and executed in STM32H743 MCU2.Wanted to know are there any optimization techniques to improve speed like using I cache ...
Hi guys,My code is acting strange, when it seems to intermittently get stuck during the HAL_Init() function at the start of the code. The issue never throws an error ( but the debugger constantly pauses at HAL_TIM_PeriodElapsedCallback() despite ther...
I'm thinking in particular about defines to influence the HAL library code e.g. USE_HAL_TIM_REGISTER_CALLBACKS.Adding user defines in MX just puts them in main.h and they are not seen by the library code.
Is there any projection when STM32F723VxT gets available? Is it projected at all?
Hello Guys,I am using a STM32H755ZI and I learned a lot about this MCU the past last months. However I am struggling with DMA. I got DMA working on one core, but I would like to use DMA on the same peripheral on both cores. I got it kinda working, bu...
Dear all,I'm trying to perform a simple blocking SPI communication with a slave (TFT driver) on my STM32F769NI-disco board.I can transmit commands without any problem but I can't receiveHere is my init code called from main(): static void MX_SPI2_Ini...
