Hi tan keat hui,
1. You can use 74ls47 to decode bcd to 7 segments. But to simplify the task why don't you drive the segments directly from the 7 port pins and your program can take care of the seven segement decoding. 2. There is a real nice tutorial on software based real time clock ( SOFT RTC ) available here on this site. http://www.8052.com/tutrtc.phtml Regards, Prahlad Purohit |
