STM32L072 Periodic 4ms time drift on RTC/LPTIM 1Hz interrupt using LSE
Hello,I am working with an STM32L072 and trying to generate a 1Hz interrupt with as little time drift as possible. For this, I am using the RTC wakeup interrupt at 1Hz, with the LSE (32.768 kHz quartz, 10 ppm) as the clock source.On several products,...
