I²C Serial Real-Time Clock
I would also suggest you to try a different library this one is vs1337 DS – so I’m not sure it’ll work. Need help with this. This bit is enabled logic 0 when power is first applied.
Please provide as much detail as possible in your answers. Internet of Things IoT Platform.
Looking again at your serial monitor printout, it looks like your code was not able to set the clock time. Here is the wiring scheme which I used I am unable to get what I am doing wrong.
Wiring diagram for the DS1337 RTC.
Check that its oscillator is working. Prices are in U. Resubmit your request using a business or educational e-mail address registered with Maxim Contact your Maxim distributor Thank you for your interest in Maxim.
The A2IE bit is disabled logic 0 when power is first applied. Communications Wireless and RF. I am not sure about bit masking here. Sign up using Facebook. What happens if I omit the pullup resistors on I2C lines? What changes did you make? Embedded Security Security Managers. I’ve also seen some code that did the communication using Wire lib directly.
Our free samples program limits the quantities that we can provide to each customer per calendar year. Maybe it’s the device address that’s wrong, or a problem with the wiring. If there’s a signal going near the crystal pins, the internal IC registers will get corrupted.

The table below shows the square-wave frequencies that can be selected with the RS bits. Visit My Quotes Thank you! I’d try that as well sorry, I don’t have the link. Who is the End Customer? Then you’ll get all sort of weird symptoms.
If you get a clean 32,Hz square wave, then it’s oscillating properly. Sorry, but we are unable to process sample requests from non-business or non-educational e-mail addresses via this site. 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 is least. Unfortunately, we are unable to place your order due to restrictions on your account.
If you feel that you have received this message in error, please contact samples-admin maximintegrated. Predicting an Application Lifetime. First Middle Lastname email mycompany. Sign up using Email and Password. These bits control the frequency of the square-wave output when the square wave has been enabled. And with 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.
Timekeeping operation is maintained with V CC as low as 1.
