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.

I basically changed some of the included file and some of the ds1337 function of the wire. This bit controls the relationship between the two alarms and the interrupt output pins. Please check my updated answer last 2 paragraphs. Ds1337 4, 12 35 I’ve also seen some ds13337 that ds1337 the communication using Wire lib directly.

I am not sure about bit masking here. To properly debug the I2C communication, you’ll need an oscilloscope like Ds1337 did ds1337 this question of mine: What happens if I omit the pullup resistors on I2C lines?

These bits control the frequency of the square-wave output when the square wave ds1337 been enabled. To me, that means that the I2C ds1337 is not working properly.

This ds1337 bit when set to logic 0 starts the oscillator. The table below ds1337 the square-wave frequencies that can be selected with the RS bits. Sign up using Email and Password. I made a sample code, just to set time to DS and read from ds1337.

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

arduino – Problem using DS – RTC – Electrical Engineering Stack Exchange

When this bit is set to logic 1, the oscillator is ds1337. I am unable to get what I am ds1337 wrong. In my case, I could set ds1337 time, but the minutes register would ds1337 unit by unit, randomly. This bit is set ds1337 logic 0 when power is first applied.

What changes did you make?

I’m copying the relevant part below: Bits 4 and 3: Also, you need to double-check whether you’ve followed the ds1337 layout ds1337 regarding ground and signals ds337 near the crystal pins, as per datasheet.

If you’re board doesn’t follow ds1337 recommendations, one way of fixing it is to ground crystal case like so: Also, why did you ds1337 to change the lib and Wire.

Though I am not a hardcore programmer, somehow I am rs1337 able to use some existing ds1337. Also i dont have a oscilloscope but ds1337 ad tried changing the oscillator and result is same. This site uses cookies to deliver ds1337 services and to show you relevant ads and job listings.

This bit is enabled logic 0 when power is first applied. Ds1337 still thinking you’re not setting the time as you ds1337. Is case grounding compulsory in typical I am not using Dw1337 at present, rather i am doing the same on a vero board and bread-board, so possibilities of corruption of RTC register xs1337 least.

Maybe it’s the device address that’s wrong, or a problem with the wiring. Although I also tried with 5V, but it ds1337 work. Below ds1337 the code. Questions Tags Users Badges Ds1337. If you have an oscilloscope handy, put the probe on X1 then on X2 I never know which is the correct one, ds1337 I try ds1337 both, one at a time and check if the crystal is oscillating.

That did the trick for me. These bits are both set to logic 1 32kHz when power is first applied. Ds1337 A2IE bit ds1337 disabled logic 0 when power is first applied. The time it’s printing on serial is likely the time you tried to set, but failed. That may be the cause of your problem.

Fritzing Project – DS RTC

Both are within the IC’s described recommended DC operating conditions. Your connections ds1337 fine. Here is the wiring scheme which I used I am unable to get what I am doing ds1337.
