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

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
