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 February 06, 2013 at 15:43Im using a quadrature encoder hooked up to TIM3-CH1/2 and it works fine, counting both edges, up and down. First question is how to read the TIM3-counter values from within a regular (50 us) ISR. Using TIM_GetCoun...
