Hy friends!

I need to use an RTC (Real Time Clock) model PCF2131 (NXP) with LPC1857 microcontroller. Is there any example or SDK about it?

Thankyou very much.

Hi @xiangjun_rong!
Thanks a lot for your attention!
I will use PCF2131. Will the PCF2129 example work well with the PCF2131?

Thank you very much!

Hi,

I suppose they are similar from interface perspective and RTC registers.
