I am using a LCD display ( basically in a project involving 8051 MCU , and serial communication with my pc through hyperterminal)
And it is not showing characters after displaying the first 8.
So pleas help me out of the problem.

Thanks in advance

have u configure the lcd before sending data to it?
 

Actually i wanted the possible CG RAM addresses of that 8x2 LCD..
8x2 LCD is not mentioned in the 8051 book that i have.

It will help you completely for understanding LCD at all.
 
Yes, the code is most likely expecting a 16x2 display. You would need to advance to the second line (and respective cursor position, e.g. 0x40) after the first 8 characters.
 

If you would like us to help you, I would suggest posting or uploading your code and a schematic if available.

It sound like the cursor is not being positioned correctly or the LCD was not initialized correctly.

The code to change address is 0x80+ the address(0x40). So the data for the start of line 2 command is 0xc0 and the start of line 1 is 0x80.
