Arduino, SPI and the DS RTC – Page 2
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 first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon. 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. You do not have the correct permissions to perform this operation. Thanks for your help. Please, contact us at support mbed.
I really want to study. I got the same result like before. Good luck, let us know how you get on! I hope someone can help me.
The problem can be seen in the register map above. By continuing to use our site, you consent to 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. Hi Wen, The first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon. 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”.
Looking at the datasheet at: I think it should be ” It seem silly to ask but it is often the simple things that trip us up.
I want to use DS control mbed on or off on right time. The DS datasheet shows datashee read address dayasheet 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 have got answer.
Can you also provide a schematic? 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.
