Thread: a "clock" ({hours,minutes}) with a PIC
face BY : Andrea Aizza email (remove spam text)


I am a beginner of PIC designing. I have to include a time reference in my design. This means I would like to implement a clock which gives me the time i.e. {hours,minutes}. An idea is to use the an adequate clock signal and use it to increment a counter inside the PIC; maybe this is a stupid idea. Obviously this means the PIC should be always switched on, with the consequent power consumption. Are there more efficient solutions in terms of power consumption? Is it there a *COMMON* way to solve this problem?

Thanks for your help,
