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...


Two UART interfaces via DMA fail in DEBUG mode

HiI have a custom board with STM32U575. It has two UART interfaces:- UART1: Terminal interface (routed to the ST-Link header)- UART3: Communication with additional MCU on the boardAs the system is very busy, I implemented both UART to receive their d...
