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...
I recently got trouble after my STM32F103CB (128KB/20KB) started to misbehave. I ask few guys but seems no answer. Is there any way one can detect loosely cloned STM32 MCU?
Hi All,We are using the STM32H747XI Discovery board and we need to use the onboard microphone to get voice recorded and send it over Ethernet.From https://os.mbed.com/teams/ST/wiki/DISCO_H747I-modifications-for-Ethernet, to use the Ethernet port, we ...
Hi, I need to write a variable, like ID , for a new design.This ID during the normal program execution the user can change in order to assing a new ID. In the next re-start this new ID must to be can read.someone could me help to implement this funct...
Hi,I am using STM32H743ZIT6 in my design but due to the availability issue I am planning to use STM32H723ZGT6 as it is a P2P compatible.I have the below queries related to the UART and SPI:For UART :Can RS485 be used with USART ?For debug UART3 in 72...
Hello,For efficiency reason I need to use only the LL, so I enable the LL flag in the CUBEMX configuration.I would like to have the ISR defined as __weak, so that I can write my own version without replacing manually the ISR.I know that using HAL dri...
