Im playing the the serial lcd file and have got it working to the point my lcd is displaying stuff i write. woo hoo. the problem im having is getting the position of the charecters. here is what i have done so far.

void selectLineOne(){
Serial.print(0xFE, BYTE); //command flag
Serial.print(0x0C, BYTE);

the second line is the command needed to position the cursor. the problem is that the lcd is asking for a quordanent after the command 0x0C in the syntax 0c0C [line] [row]. my question is how do i pass this command with line and row numbers in place. if you add them after the 0x0C 1 1 like that you get an error.

Im sure there is a simple fix to this but im scratching my head. thanks in advance and if there is any other info you need to answer this let me know.

this is right out the manual for my lcd
Set Cursor Position
Syntax hexadecimal 0xFE 0x0C [col] [row]
Parameter Length Description
[row] [col] 2 bytes Put cursor at location specified row and col

Are you using

Serial.print(col, BYTE)
Serial.print(row, BYTE);

?

If not, try it. If that doesn't work, perhaps it's looking for ASCII values:

Serial.print(col + '0', BYTE)
Serial.print(row + '0', BYTE);

?
