#179582 - Back to basics? Responding to: ???'s previous message |
Thanks Erik and Andy.
Guessed as much. Looks like some maths has to be done. @32.768Khz each clock period is roughly 30.5 us. So once every 2^15 number of bits I will clock 1 sec approx. Once this basic unit is reached, then I just have to intilaize counters to roll over at 60, 60, 24 etc to display HH:MM:SS. In short I just have a 2^47 bit up-count timer which I need to read and display as required. Who said life is easy ?! Raghu |

which tolerance would you prefer, and why?? :) | 01/01/70 00:00 |
