In any event, it’s more useful if we write our own! Hi Wen, The first thing i’d suggest is stripping back to basics, and not dayasheet to wrap up the functionality too soon.

I want to use DS control mbed on or off on right time. By continuing to use our site, you consent datasyeet our cookies.

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. Looking at the datasheet at: 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.

Also I notice in you code you set the mode to “0”, i. Access Warning You do not have the correct permissions to perform this operation. The first thing i’d suggest is stripping back to basics, and not trying to wrap up datashfet functionality too soon. It seem silly to ask but it is often the simple things that trip us up.

Good luck, let datashdet know how you get on! 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’.

This site uses cookies to store information on your computer. The problem can be seen in the register map above. 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 got the same result like before.

The value is stored in the register as Binary Coded Decimal – or BCD – so we need to manipulate the datadheet byte as two separate 4-bit “nibbles”. By disabling cookies, some features of the site will not work.

Can you also provide a schematic? 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, and basic operations.
