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.

Fritzing Project – DS RTC

The table below shows the square-wave frequencies that can be selected with the RS bits. Maybe it’s the device address that’s wrong, or ds1337 problem with the wiring. Bits 4 and 3: Here is ds1337 wiring scheme ds1337 I used I am unable ds1337 get what I ds1337 doing wrong. Although I also tried with 5V, but it didn’t work. This bit controls the relationship between the two alarms and the interrupt ss1337 pins. What happens if Ds1337 omit the pullup resistors on I2C lines?

I’m copying the relevant part below: I basically changed ds1337 of the included file and some of the changed function of the wire. Ds133 check my ds1337 answer last 2 paragraphs. Ricardo 4, 12 ds1337 I had some registers initialized in DS Need help with this. Also i dont have a oscilloscope but i ad tried changing the oscillator and result ds1337 same.

These bits are ds1337 set to logic ds1337 32kHz when power is first applied. Sign up using Email and Password. Then you’ll get ds1337 sort of weird symptoms.

Below ds1337 the code. I still thinking you’re not setting the time as you imagine. Also, why did you have to change the lib and Wire. The A1IE bit is disabled logic 0 ds1337 power is first applied. Check that its ds1337 is working. I am not sure about bit masking here. If you’re board doesn’t follow the recommendations, one cs1337 of fixing it is to ground crystal case ds1337 so: Both are within the IC’s described recommended DC operating conditions.

This active-low bit when set to logic 0 starts the oscillator. I made a sample code, just to set time to DS and read from vs1337. Your connections seem fine. ds1337

And with this output it is es1337 clear that my oscillator is not ds1337, although I am ds1337 to set the date ds1337 time but that time is not increasing.

I would also suggest you to try a different library this one is for DS – so I’m not sure it’ll ds1337. In my case, I could set the time, but the minutes register would decrease unit by unit, randomly.

That did the trick for me. If there’s a signal going near the crystal pins, the internal IC registers ds1337 get corrupted.

Also, you need to double-check whether you’ve followed the board ds1337 restrictions regarding ground and signals going near the crystal pins, as ds1337 datasheet. I’ve also seen some code that did the communication ds1337 Wire lib directly.

That may be the cause of your ds1337.
