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 eatasheet it to be.

Bit 7 is always ‘0’. In any event, it’s more useful if we write our own!

I have got answer. I dont have a DS to hand, but you might consider using a program like this with some simple printf style debug, dwtasheet basic operations.

I want to use DS control mbed on or off on right time. Hi Wen, The first thing i’d suggest is stripping back to basics, and not trying to wrap dagasheet the functionality too soon. 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: You do not have the correct permissions to perform this operation.

The problem can be seen in the register map above. Can you also provide a schematic? Looking at the datasheet at: 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. Accept and hide this message. It seem silly to ask but it is often the simple things that trip us up.

The value is stored in the register as Binary Coded Decimal – or BCD – so we need to manipulate datsheet 8-bit byte as two separate 4-bit “nibbles”. Thanks for your help.
