I really want to study.

The value is stored in the register as Binary Coded Decimal – or BCD – so we need to manipulate the 8-bit byte as two separate 4-bit “nibbles”. 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: If you are not happy with the use of these cookies, please review our Cookie Policy to learn how they can be disabled.

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.

Please, contact us at support mbed. Good luck, let us know how you get on! In any event, it’s more useful if we write our own!

The search term ‘Bcd2Dec’ appears regularly on the Web but I haven’t been able to discover if it’s native to Arduino. Can you also provide a schematic?

Access Warning You do not have the correct permissions to perform this operation.

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. Hi Wen, The first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon.

I want to use DS control mbed on or off on right time. I think it should be ” 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.

Bit 7 is always ‘0’. The first thing i’d suggest is 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. Thanks for your help. Accept and hide this message. I have got answer. Also I notice in you code you set the mode to “0”, i. I dont have a DS to hand, but you might consider using a program like this with some simple printf style debug, and basic operations.
