I looked at this project.
I get lots of errors from Proteus about read timings,
and the keyboard is not read at all.
The keyboard code is so mixed up with reading and writing the hardware
it is very hard to make out and debug.

If I were you, I would write my own code or try another project.

This is one of Binu's and some of his other projects had problems.

Honestly I don't think it is worth trying.
Binu projects often don't work, so even if you/I get the keyboard
working something else will need fixing.

I did a Google search for "college bell 8051 " and got several hits.
I'm sure you can find a good project that is right for you.

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.
