I hope someone can help me. Bit 7 is always ‘0’.
The 8-bit seconds register stores the units ss1306 seconds in bits 0, 1, 2 and 3 and the tens of seconds in bits 4, 5 datashset 6. 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 xs1306. It seem silly to ask but it is often the simple things that trip us up. Looking at the datasheet at: In any event, it’s more useful if we write our own!
Also I notice in you code you set the mode to “0”, i. Please, contact us at support mbed. Accept and hide this message. Access Warning You do not have the correct permissions to perform this operation.
I want to use DS control mbed on or off on right time. The first thing i’d suggest is stripping back to basics, and not trying to wrap up the functionality too soon.
The DS datasheet datashedt 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 got the same result like before. Good luck, let us know how you get on! datasheer

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 search term ‘Bcd2Dec’ appears regularly on the Web but I haven’t been able ds1360 discover if it’s native to Arduino.
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 dz1306 data read from the register is as we’d expect it to be. By continuing to use our site, you consent to our cookies.
