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...

PWM capture with TIMER (with DMA)

I have configured TIMER2 to capture PWM input (Basically PWM inputmode). Both CCR1 and CCR2 captures period and ontime of the PWM signal respectively. I configured DMA to captures these two registers CCR1 and CCR2 by configuring array of two 32bit bu...
