New possibilities for the ultra-low power segment!

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...


Resolved! How does the STM32 knows where should the .BSS section be addressed,and what's the range,when the chip startup initially?

How does the STM32 knows where should the .BSS section be addressed,and what's the range,when the chip startup initially? We know that firmware downloaded into the flash contains section information like .text ,.data ect,while .bss section should be ...

Why can't I read from more than one UART?

Hello community, I'm new to ST-MCUs, so maybe this question is very basic. I'm developing an application for a customer board with a STM32L051R6TX.For Communication we use USART1 und USART2, for logging I activated LPUART1.On USART1 und USART2 I get ...

SRAM Parity bit check, Hardfault

Hi everyone,I am trying to implement SRAM Parity bit check in my application. But when I am enabling it from option byte. and then it is going into Hardfault whenever I am going into debug mode before running application even it is going into .Hardfa...
