Hello friends, I need to implement a clock on pic16F873. Need I to add a real time chip on my project? Can I to build this clock with the pic timer? I know that using a 4Mhz clock will get exactly 1uS cycle. Is this enough? Thanks in advance! --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
