Hi Luca, Yes this is possible. The easiest way is just to enable the RT1PS interrupt. Please take a look at the Technical Reference Manual Section 18.2.6 Real-Time Clock Interrupts and let me know if you need some help writing this code. "RT1PSIFG can be used to generate interrupt intervals selectable by the RT1IP bits. RT1PS is sourced with the output of RT0PS, which is 128 Hz (32768/256 Hz). Therefore, intervals of 64 Hz, 32 Hz, 16 Hz, 8 Hz, 4 Hz, 2 Hz, 1 Hz , or 0.5 Hz are possible. Setting the RT1PSIE bit enables the interrupt." Hopefully this helps. David
