Thank you for your reply and suggest. Nope, I was not here last year. I am doing a time and temperature talking devices specially for the blind using DS1307, DS1620, EMIC and PIC16 chips. I try to read first and ask you again My supervisor always asked me why I used PIC 16 instead of PIC 18. Last year in our school we were taught PIC 18. So, he asked me it would be easier if I use PIC 18. In fact I used PIC 16 because i saw lots of clock project uses PIC 16 in the internet.
