PCF2127T

Does anyone knows about a library for PCF2127T NPX's RTC. I need it for I2C communication with LCD to display the date.

never seen one on the forum ,

you could check this lib - https://github.com/JChristensen/DS3232RTC -as a basis and check the datasheet of NXP (which are normally very good) where to change them.

If you cannot do that, maybe someone will if you send them such an RTC ;)

Thanks robtillaart.

I dont have experience with RTC, but i need one pretty accurate (I found this IC), and where you are refering to change the library, you are talking about modify the register?

How accurate do you need? DS3231/32/34 are some of the more accurate low-priced RTCs, 2ppm.

Thanks Jack, Now I know about DS32... I'm gonna change the RTC, there's a lot of support for this IC. And it's more accurate than PCF2127 (3ppm). Thanks a lot. :D
