The next step is to read the Hours, Minutes and Seconds registers, decypher how the data is presented and display it on the Arduino serial monitor. Access Warning You do not have the correct permissions to perform this operation.

In any event, it’s more useful if we write our own! The 8-bit seconds register stores the units of seconds in bits 0, 1, 2 and 3 and the tens of seconds in bits 4, 5 and 6.

Thanks for your help. It seems sensible to start with the seconds register since this is obviously changing more rapidly than minutes or hours and will enable us to see if the data read from the register is as we’d expect it to be. The first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon.

Good luck, let us know how you get on!

I got the same result like before. Bit 7 is always ‘0’. Please, contact us at support mbed.

The search term ‘Bcd2Dec’ appears regularly on the Web but I haven’t been able to discover if it’s native to Arduino. Also I notice in you code you set the mode to “0”, i.

Hi Wen, The first thing i’d suggest datasheey stripping back to basics, and not trying to wrap up the functionality too soon. It seem silly to ask but it is often the simple things that trip us up. This site uses cookies to store information on your computer.

I have got answer. By disabling cookies, some features of the site will not work. I want to use DS control mbed on or off on right time. Looking at the datasheet at: By continuing to use our site, you consent to our cookies.

Datasueet think it should be ” The DS datasheet shows the read address of the seconds register is 00h 0x00 so we can modify the loop function in the sketch above to show the contents of that register: I really want to study.

I dont have a DS to hand, dataasheet you might consider using a program like this with some simple printf style debug, and basic operations. Accept and hide this message. The problem can be seen in the register map above.

Can you also provide a schematic?
