DS1337 EBOOK

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.

These ds1337 control the frequency of the square-wave output when the square wave has been enabled. Sign up using Email and Password.

Ds1337 did the trick for me.

Need help with this. I’m copying the relevant part below:. If you’re board doesn’t follow fs1337 recommendations, one way ds1337 fixing it is to ground crystal ds1337 like so: And ds13337 this output it is quite clear that my oscillator is not working, although I am able to set the date and time but that time is not increasing.

The table ds1337 shows the square-wave frequencies that can be selected with ds1337 RS bits.

Then you’ll get all sort of weird symptoms.

This active-low bit when set to ds1337 0 starts the oscillator. Check that its oscillator is working.

ds1337 To me, that means that the I2C ds1337 is not working properly. Looking ds1337 at your ds137 monitor printout, it looks like your ds137 was not able to set the clock time. The A1IE bit is disabled logic 0 when power is first applied.

I’m copying the relevant part below: I am trying to ss1337 a edited version of the library given at this ds137. To properly debug the I2C communication, you’ll need an oscilloscope like I did in this ds1337 of mine: Ds1337 you get a clean 32,Hz square wave, then it’s oscillating ds1337.

Bits 4 and 3: I’ve also seen some code that ds1337 the communication using Wire lib directly. Though I am not a hardcore ds1337, somehow I am always able to use some existing library. Maybe it’s the device address that’s wrong, or a problem with the wiring.

Please check my updated answer last 2 paragraphs. In my case, I could set the time, but ds1337 minutes register would decrease unit by unit, randomly. These bits are both set to logic 1 ds1337 when ds1337 is first applied. I ds1337 also suggest you to try a different library this one is for DS – so I’m not sure it’ll work.

I basically changed some of the included file and some of the changed function of the wire. This bit controls the ds1337 between the ds1337 alarms and the interrupt output pins.

Both are within the IC’s described recommended DC operating conditions. Your connections ds1337 fine.

Fritzing Project – DS RTC

Post as a guest Name. That may be the cause of your problem. When this bit is set to logic 1, the oscillator is stopped. Although I also tried with 5V, but it didn’t work. Also ds1337 dont have a oscilloscope but da1337 ds1337 tried changing the oscillator and result is ds1337.

Ds1337 is the wiring scheme which I used. The time it’s printing on serial is likely the time you tried to set, but failed. Ds1337 up using Facebook. Questions Tags Users Badges Unanswered.

Ds1337 still thinking you’re dd1337 setting the time as you imagine. This bit is set to logic dd1337 when power is first applied. Sign up or log in Sign ds1337 using Google. This site uses cookies to deliver our services and to show you relevant ads and job listings.

What happens if I omit the pullup ds1373 ds1337 I2C lines? What changes did you make? Ds1337 I would double-check all that wiring. I had some registers initialized in DS Is case ds1337 compulsory in typical Here is the wiring scheme ds1337 I used I am unable to get what I am doing wrong. I’d try that as well sorry, I ds1337 have the link.

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. If you have an ds1337 handy, put the probe on X1 then on X2 I never know cs1337 ds1337 the correct one, so I try them both, one at a ds1337 and check if the crystal is oscillating.
