Hi Sohelin this link is the connection 'ive made. i use a pic16f877 to drive the display the portE is connected to the control bits and the portD to the data bits.
http://roboticsindia.com/public/images/lcd/lcd.gifi can:
initialize & clear the dsiplay
change the cursor to any position in the first row & write
can write all the LCD memory. fills the screen (2 rows) with the same caracter
set the cursor in any position in the second row and came back to the first row
i can't:
set the cursor in the secon row & write a character in that position
The data sheet tell me thah is 100% compatible whit the HITACHI HD44780. and thats not true,
because i've change the response timings to initialise & write.
i really don't know what to do, i've tried everithing .
thanks
