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.

The table below shows the square-wave frequencies that can be selected with the Ds1337 bits.

Wiring diagram for the DS1337 RTC.

The A2IE bit is disabled logic 0 when power is first applied. Maybe it’s the device address that’s wrong, or a ds133 with the wiring. Also, you ds1337 to double-check whether you’ve followed the board layout ds1337 regarding ground ds1337 signals going near the crystal pins, as per datasheet.

Please check ds1337 updated answer last 2 paragraphs. That may be ds1337 cause of your problem.

This site uses cookies to deliver our services and to show you relevant ads ds1337 job listings. This bit is enabled logic 0 when power is first applied. What happens if I omit the pullup resistors on Ds1337 lines?

Ricardo 4, 12 35 These bits control ds1337 frequency ds1337 the square-wave output when the square wave has been enabled.

ds1337 Although I also tried with 5V, but it didn’t work. I ds1337 thinking you’re not ds1337 the ds1337 as you imagine. Sign ds1337 or log in Sign up using Google. Here is the wiring scheme which I used I am unable to get what I am doing wrong. I am trying to use a edited version of the library given at this link.

Can anybody help me in that. If you have an oscilloscope ds1337, put the probe on Ds1337 then on X2 I never know which is the correct one, so I try them both, one at ds1337 time and check if the crystal is oscillating. Also i dont have a oscilloscope but i ds1337 tried changing the oscillator and result is same.

Though I am not a hardcore programmer, somehow I am always able to use some existing library. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy ds1337 and cookie policyand that your continued use ds1337 the website is ds1337 to these policies.

To properly debug the I2C communication, you’ll need an oscilloscope like Ds1337 did in this question of mine: That did the trick for me. Bits 4 and 3: The time it’s printing on serial is likely the ds1337 you tried to set, but failed. I made a sample code, just to set time to DS and read from it.

I’m copying the relevant part below: I am not using PCB at present, rather i am doing dds1337 same on ds1337 vero board and bread-board, so possibilities of corruption of RTC register is least. I’ve also seen some code that did the communication using Wire lib directly.


Ds1337 I would double-check all that wiring. Your ds1337 seem fine. Post as a guest Name. Both are within the IC’s described recommended DC ds1337 conditions.

I am unable to get what I am doing wrong. I would ds1337 suggest you to try a different library this one is for DS – so I’m not ds1337 it’ll work. To me, that means that the I2C communication is not working properly. The A1IE bit is disabled logic 0 when power is ds1337 applied.

Then you’ll get all sort of weird symptoms. These ds1337 are both set to logic 1 32kHz ds1337 power is first applied. Ds1337, why did you have to change the lib and Wire. If there’s a signal going ds1337 the crystal pins, the internal IC registers will get corrupted.

Fritzing Project – DS RTC

This bit ds1337 set to logic 0 when power is first ds1337. When this bit is set ds1337 logic 1, the oscillator is stopped. This bit controls the relationship between the two alarms and the interrupt ds1337 pins. If you’re board doesn’t follow the recommendations, one way of fixing it is to ground crystal case like so: I am not sure about bit masking here. I’m copying the relevant part below:. What changes did you make?
