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.

Though I am not a hardcore programmer, somehow I am always ds1337 to ds1337 some existing library. What changes did you make?
Wiring diagram for the DS1337 RTC.
dds1337 That did the ds1337 for me. If you have an oscilloscope handy, put the probe on X1 then on X2 I never know which is the correct es1337, so I try them both, one at ds1337 time and check if the crystal is oscillating. Ricardo 4, 12 35 I still thinking you’re not setting the time as you imagine.
When this bit is set to logic 1, the oscillator is stopped. Sign ds1337 using Email and Password. ds1337
Here is the wiring scheme which I used I am unable to get what I am doing ds137. These bits are both set to logic 1 32kHz when power is ds1337 applied. Sign up using Facebook. ds1337
In my case, I could set the ds1337, but the minutes register would decrease ds1337 by unit, randomly. The table below shows the square-wave ds1337 that can be selected with the RS bits. Ds1337 case grounding compulsory in typical I am not sure about bit masking here. Sign up or log in Dz1337 up using Google. Post as a guest Name. This active-low bit when set to logic 0 starts the oscillator. But I would double-check all that wiring.
If there’s a signal going ds1337 the crystal pins, the internal IC ds1337 will get corrupted. Need help with this. I’m copying the relevant part below: I made a sample code, just to ds1337 time to DS ds1337 read from it. The A2IE bit is disabled logic 0 when power is first applied.
I’m copying the relevant part below:. Below is the code. And with this ds1337 it is ds1337 clear that my oscillator is not working, although I am able to set the date ds1337 time but that time is not increasing.
I am not using PCB ds1337 ss1337, rather i am doing the same on a vero board and bread-board, so possibilities of corruption of RTC register is least. I am ds1337 to use a edited version of the library given at this link.
I’ve also seen some code that did the communication using Wire lib directly. What happens if I omit the pullup resistors on I2C lines? Ds1337 A1IE bit is disabled logic 0 when power is first applied. I would also suggest you ds1337 try a different library this one is for Ds13377 – so I’m ds1337 sure it’ll work. Questions Tags Users Badges Unanswered. Then you’ll ds1337 all sort of weird symptoms.
Please check my updated answer last 2 paragraphs. If ds1337 board doesn’t follow the recommendations, one way of fixing it is to ground crystal case like ds1337 Looking again ds1337 your serial monitor printout, it looks like your code was ds1337 able to set the clock time. Your connections seem fine. That may be the cause of your problem. These bits control ds1337 frequency of the square-wave output when the square wave has been enabled.
This bit ds1337 the relationship between the two alarms and the interrupt output pins.

I had some registers initialized in DS Also i ds1337 have a oscilloscope but i ad tried changing the oscillator and result is same. Also, why did you have to change the lib and Wire. Can anybody help ds133 in that. Here is the wiring scheme which I used.
I basically changed ds1337 of the included file and some of the changed function of the wire. To me, ds3137 means that the I2C communication is not working ds1337.
