Ya i need to make these circuits at a low cost...
Actually i am facing a major problem with chips that do not have a TMR0 interrupt (12C508A).
All the devices need to have a basic accurate clock running in the background.
How can a implement a hour minute clock on PICs which do not have the TMR0 interrupt (but have timer0) and do other stuff also without much interference from the clock routine?
Is there a way i can do it in PICBASIC PRO ???
