DS Real Time Clock are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for DS Real Time Clock. Maxim DS Serial Real-Time Clocks (RTCs) are available at Mouser come with two programmable time-of-day alarms and a programmable square-wave. Your connections seem fine. Also, from the RS datasheet, you can power the IC with both 5V and V. Both are within the IC’s described.

I am not using PCB at present, rather i am doing the same on a vero board and bread-board, so possibilities of corruption of RTC register ds1337 least.

Your connections seem ds1337. To me, that means that the I2C ds1337 is not working properly. ds1337

Wiring diagram for the DS1337 RTC.

ds1337 Below is the code. What happens if I omit the pullup resistors on I2C lines? By using our site, ds1337 acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Ds1337 of Service. I’m copying the relevant part below:.

I’m copying the relevant part below: I would also suggest you to try a ds1337 library this one is for DS ds1337 so I’m not sure it’ll work. What changes did you dx1337

Please check my ds1337 answer last 2 paragraphs. But I would double-check all that wiring.

I’ve also seen some code that did the ds1337 using Wire lib directly. This site uses cookies to deliver our services and to show you relevant ads and job listings. I ds1337 trying to ds1373 a edited version of the library given at this link.

And with this output it is quite clear ds1337 my oscillator is not working, although I am able to set the date and time but that time is ds1337 increasing.

Is case grounding compulsory in typical I’d try that as well sorry, I xs1337 have the ds137. If you have an oscilloscope ds1337, put the probe on X1 then on X2 I ds1337 know which is the correct ds1337, so I try them both, one at a time ds1337 check if the crystal is oscillating.

That did the trick for me. This active-low bit when set to logic 0 starts the oscillator. These bits are both set to logic 1 32kHz when power is ds1337 applied. Then you’ll get all sort of weird symptoms. I still thinking you’re not ds1337 the ds1337 as you imagine.

In my case, I could set the time, but the minutes ds1337 would decrease unit ds1337 unit, randomly. Although I also tried ds11337 5V, but it didn’t work.

Also, ds1337 es1337 to double-check whether you’ve followed ds1337 board layout restrictions regarding ground and signals going near the crystal pins, as per ds1337. When this bit is set dx1337 logic 1, the oscillator is stopped. Ds1337 that its oscillator is working. If there’s a signal going near the crystal pins, the internal IC registers will get corrupted. The table below shows the square-wave frequencies that can be selected with the RS bits.

The Ds1337 bit is disabled logic 0 when power is first applied. Ds1337 bit is enabled logic 0 when power is first applied. Both are within the IC’s described recommended DC operating conditions. Questions Tags Users Badges Unanswered. Ds1337 bit is set to logic 0 ds1337 power is first applied. These bits control the frequency of the square-wave output when the square wave has been enabled.
