DS chip is commonly used as DS RTC module which comes with a 32 kHz crystal and on-board battery backup all in a small SIP. DS Real Time Clock Module with Battery Backup uses the DS chip. DS chip uses a simple serial interface. Example code available for Arduino, . Introduction. DS is a trickle charging clock chip, launched by DALLAS in America. With a built-in real-time clock/calendar and a byte.

Peter SimpsonMostezBeja and 3 others d1s302 this. It will only start running if it has had its date and time set since the last time it acquired at least the battery backup power. I made those changes so that I could use the DS through a NoviceGuard board’s twelve way connector.

Peter Simpson likes this. Yes, Virginia, there were once clocks without batteriesthen it will start up again. That I DO feel I can complain about! My Sheepdog Software pagesanother of this page’s editor’s sites. The three pins for the interface should avoid to use the internal pull-up resistors of the Arduino.

RTC DS1302 Real Time Clock Module

Hi rwblinn and thanks for the promising library. Your name or email address: Use it with Arduino 1. I’ve often been prevented from leaving bad feedback in ds1032 circumstances. The DS can be easily connected to the Arduino. He was using the version 1. Set the RTC time year, monthdayofmonthhourminuteseconddayofweek get: The program uses about 5, bytes. That’s about it, for now. For the experiment, used a sunfounder RTC ds with the pins marked: I used a “” cell.

Various commands are accepted via the serial line using Asyncstream: This allows us to use our “big” computer to set the date and time in the module “for all time”, and not need a way to do the setting in whatever application we are using the RTC for.

Revise the values on those lines to some moment in time about a minute from when you expect to run to program.

You don’t need to worry about it, as we won’t be using it. The Year ‘0’ isand not or If you dig into the software, you will find the lines that sets the RTC to initial date and time values. There are several “real time clock” RTC chips which can be connected to an Arduino. A crystal of The attached library fixes this issue.


The last clock pulse of the address using the rising edge is also the first clock pulse of the data to read using the falling edge. I am just going to assume that whoever put “RST” in the silkscreen of the module was confused, or working in a weak second language.

And I changed the next two lines, setting the program up to use line 8 for IO, and line 7 for the CE signal.

No, create an account now. Set the time manual befor uploading. Dw1302 little work with a magnifying glass and the pinout diagram convinced me that This is how I would have wrapped this library.

We’ll see how I get on!
