LCD DISPLAY 20 x 2 Cursor Issue

[Nishanth]

I am familiar in 16x2 LCD Display. Now i changing LCD Display from 16x2 to 20x2.Characters are displaying fine but, I am facing some problems are following:-

1. In 16 x 2 LCD Display if i use 0x80 command means, the cursor will go to first line , first position. If I try 0x82 means first line third position will cursor will set.
2. Same thing like if i use 0xC0 command means, the cursor will go to Second line , first position. If I try 0xC5 means second line sixth position will cursor will set.

These are commands are followed in 16x2 display. I tried same thing in 12x2 display, is not working. Help me to solve this problem.

Have a look in the dispaly's datasheet or the datasheet of the LCD controller used on the display. The required commands should be listed there.
