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...
Posted on April 05, 2017 at 16:45Hi, I'm using stm32CubeMX v4.20 and after changing systick priority to 15(lowest) my project runs into hardware failure. If i changed back to zero, problem disappears. Any Inside on why?best regards,Tony
Posted on April 05, 2017 at 12:04On the STM32L431, there's an erratum described in STM32L431xx Errata sheet (STM32L431xx device limitations / DM00218224). It allows to reset COMP1 and COMP2 despite of the LOCK bit being set.My question: What happens...
Posted on April 05, 2017 at 16:20Hi,We are using STM32 internal RTC with 32.768 KHz LSI RC clock. We are observing very large drift in time(Approx 3min lag in 1 Hour).We have gone through the RTC calibration application note.But that requires manual...
