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...


EEPROM emulation error when using TIM timebase

I am using the example project from the xcube eeprom v3.0.0 as a reference to add EEPROM emulation to my project using the STM32G431RB. The example project works fine, but my project uses FREERTOS so I have changed my timebase source to a timer. This...
