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 October 18, 2013 at 04:13Hi, I am makin a encoder interface on the et-arm stamp stm32, my problem is that maximun frequency I can get from the encoder is 30Hz and I just can measure at less 1190Hz (based in PWM_IN example) I am measuring t...
