We have noticed some shifts (lags/ advances) in RTC time in K60 micro controller.
The crystal that we used have a frequency tolerance of 20ppm. The time shift is different in different boards(same configurations).
The data sheet of K60 contains the details of RTC frequency compensation.
Then, how to implement the different frequency compensation for different boards. Is there any sample source code to implement the same?
