ohh the code is not urs, i just thot you could explain the functioning of the code, as in just the fact that in that particular header file, which pins of the muC is used to send the D0 to D7 bits of the LCD..
it could be of great help!!

The LCD is used in 4-bit mode.... that means only D4-D7 pins of LCD are used... and they are connected to P0 as
D4 - P0.0
D5 - P0.1
D6 - P0.2
D7 - P0.3
Rest you can confirm from the circuit...

but i understand they use 0.0 0.1 and 0.2 for rs rw and en of LCD!!!
is this possible??
i surely will have to modify it right???

see for my muC project (digi clk) i am using your circuit. the one i had attached before. i wrote my own program in tri C. this tri C has a LCD header file that assumes a few ports of the muC to be connected to the control i/p of the LCD (rs rw en) and some port for passing the data bits.
i read the header file and understood that the control pins of the LCD are connected to 0.0 0.1 and 0.2 pins of the muC. i wanted to know which pins has the header file assumed to pass the data bits so that i can incorporate in my design.
