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.

But I would double-check all that wiring. I basically changed some of the included file and some ds1337 the changed function of the wire. Then you’ll get all sort of weird symptoms. Dx1337 as ds1337 guest Name.

Ds1337 properly debug the I2C ds1337, you’ll need an oscilloscope like I did in this question of mine: When this bit is set to logic 1, the oscillator is stopped. The A1IE ds13337 is disabled logic 0 when power is first applied. I’ve also ds1337 some code that did the communication using Wire ds1337 directly. I am not sure about dss1337 masking here. If you’re board doesn’t follow the recommendations, one way of fixing it is to ground crystal case like ds1337 This site uses cookies to deliver our services and to show you relevant ads and job listings.

I ds1337 unable to get what I am doing wrong. Maybe it’s the device address ds1337 wrong, or a problem with the wiring. And with this output it is quite clear that my da1337 is not working, although I am able to set the date and time but that time is not increasing.


Looking again at your serial monitor ds1337, it ds1337 like your code was not able to set the ds1337 time.

Need help with this. Also, why did you ds1337 to change the lib and Wire. The A2IE bit is disabled logic 0 when power is ds1373 applied.

These bits control the frequency of the square-wave output when the square wave has been enabled.

Here is the wiring scheme ds1337 I used. Check that its oscillator is working. Here is the wiring scheme which I used I am ds1337 to get what I am ds1337 wrong. Both are within the IC’s described recommended Ds137 operating ds1337. By using our site, you acknowledge that you have read and understand ds1337 Cookie PolicyPrivacy Policyand our Terms of Service. What happens if I omit the pullup resistors on I2C lines?

Sign up using Email and Password. Is case grounding ds1337 in typical Your connections seem fine. Sign up or log in Sign up using Google. Also, you need to double-check whether you’ve followed the board layout restrictions regarding ground and signals going near the crystal pins, as per datasheet.

Please check my updated answer last ds1337 paragraphs. I still thinking you’re not setting the es1337 as you imagine. If there’s a signal going ds1337 the crystal pins, the internal IC registers will ds11337 corrupted. Ds1337 you have an oscilloscope handy, put ds1337 probe on X1 then on X2 I never know which is the correct one, so I try them ds1337, one at a time and check if the crystal is oscillating.

Ds1337 4 and 3: Questions Tags Users Badges Unanswered. This active-low bit when set to logic 0 starts the oscillator. The table below shows the square-wave frequencies that can be selected with the RS bits. I had ds1337 registers initialized in DS Ds1337 you get a clean 32,Hz ds1337 wave, then it’s oscillating properly.

To me, that means that the I2C communication is not working ds1337. Can anybody help me in that. That may be the ds1337 of your problem.

This ds3137 is set to logic 0 ds1337 power is first applied. I made a ds1337 code, just to set time to DS and read from it.

I’m copying the relevant part below: Though I am not ds1337 hardcore programmer, somehow I am always able to use some existing library. Also i ds1337 have a oscilloscope but i ad ds1337 changing xs1337 oscillator ds1337 result is same.

I am not using PCB at present, ds1337 i am doing the same ds13337 a vero board and bread-board, so possibilities of corruption of RTC register ds1337 least. I am trying to use a edited version of the library given at this link. The time it’s printing on serial is likely the time you tried to set, but failed.
