I am trying to test my MCU with the sequence bellow in order to check if i get time drift on the RTC clock.
loop on :
1. print RTC time + date
2. enter stand by mode
I tested the wake up from stand by mode with :
1. ALARM every 5 seconds
2. rising edge on the WKUP pin
This sequence make's the RTC clock drift almost immediately and the drift is getting larger and larger as the time passes ( I print the RTC clock and compare it to a stop watch).
Am i doing some thing wrong that causes this issue ? I would be happy to supply any parts of the code if needed.
