Real time clock

I want to interface an RTC to a 887 PIC. What is likely to be the easiest way to do this in Flowcode? RTCs come with various interfaces like I2C, 1 wire, 3 wire, SPI, parallel address (although I think the data is always serial). Which would be easiest to programme? Some claim to be β€industry standardβ€™ parts. Is there any standard code out here from someone who has done it before?

Hello

I think some of these devices have been previously covered on the forum.

Let us know how you get on and which device you choose to go for, the DS1307 seems popular.

Hello

Yes I think RTC is quite common term for these items now.

I have asked Sean for his example files for the DS1305 device which are attached below.
