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...


Timing issue when TIM10 interrupts HAL IWDG macro

I am using a STM32F746VET6 to drive time critical signals on up to 14 pins. I am bit banging these signals in the ISR. I was surprised to find after a benign change I started to have jitter in these signals. I tracked it down to the ISR firing during...
