The first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon. The problem can be seen in the register map above.

I hope someone can help me. Thanks for your help. I really want to study. You do not have the correct permissions to perform this operation. In any event, it’s more useful if we write our own! 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”. Can you also provide a schematic?

Looking at the datasheet at: I got the same result like before. This site uses cookies to store information on your computer. Access Warning You do not have the correct permissions to perform this operation.

Also I notice in you code you set the mode to “0”, i. 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.

It seem silly to ask but it is often the simple things that trip us up. By disabling cookies, some features of the site will not work.

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. Accept and hide this message.

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.

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

I think it should be ” I want to use DS control mbed on or off on right time. The search term ‘Bcd2Dec’ appears regularly on the Web but I haven’t been able to discover if it’s native to Arduino.

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.

Good luck, let us know how you get on! Bit 7 is always ‘0’.
