mukesh,

If you are testing sequential entry into a line of the LCD. Select the ENTRY MODE SET cmd with "I/D" set to 1. This automatically increments the DDRAM address without you having to address each char one by one.

I typically address the start location i want and then sequentially write character strings following the addressing.

I use multiline displays and have routines that address line 1 (home), line 2 (home) etc after addressing the desired line i just "blurt" out a sequential stream of characters equal to the display field of interest.

Now i do have a few displays that require addressing specific display locations. These functions are written similar to Line "X" Home but are different in the display position they address.

regards,
