Thanks a lot publisher of this tutorial. Everybody tells about the nibble sending methods and the command set for 4-wire lcd interface. You are the first to tell me about the most important part that is resetting the lcd. This thing got me all day. Now I can sleep in peace. Thanks once again. Million thanks.

@sachinmm The 8051 timer can't do 1 second. It can do 50ms so count 20 times
