I've got it such that I can see what I print on the screen, but can't seem to figure out how to clear the screen or position the cursor. All of the documentation is for the LCD in it's original (non serial state). Here are the 2 pieces of documentation I've found http://www.sparkfun.com/datasheets/LCD/HD44780.pdf http://www.sparkfun.com/datasheets/LCD/SerLCD_V2_5.PDF The SerLCD_V2_5.PDF should be the most relavent because it refers to the serial enabled LCD. This PDF file talks about setting bits and transmitting the special character 254 to tell the SerLCD you want to send a command, then transmit the number 194 is the example used to reposition the cursor. So how do you do those steps?
