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...
HelloI have configured TIM2 to throw an interrupt every 10 ms. Looking at APB1 Timer clocks clocks in the clock configuration, a prescaler of 199 with AutoReload set to 9999 should call the interrupt every 10ms. In reality the interrupt is called eve...
