Project Update!

Hello friends,
the new and improved, update of "AT89C4051 as RTC" is available for download. instead of 16x2 LCD i am using 20x4 LCD and with the help of CGRAM area in LCD (type HD44780) i created digits from 0 to 9. which are double the size of the original clock. so clock looks much better and is more impressive.. few more bugs have been fixed.

so give it a try... go to download section and DOWNLO... Read Compelte post

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?
