@shr70 There is a pre-existing RTT and RTC implementation in #8842 for all ATmega systems. It is tested and working with the ATmega1284P, but should also work with ATmega256RFR2 (testing on your system would be appreciated). It is currently waiting for @gebart and @kaspar030 to have some time to finish their reviews. |
