RTC PCF2131 example for LPC1857

[rubensjunior]

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,

pls refer to the attached code, which is based on SPI interface.

I get the code from the website:

Hope it can help you

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.
