Text LCD

My 4*20 Display with a KS066 controller was not running with the TextLCD lib. I changed the delays and the init bytes - no change. I then add the RW signal to read from the display and poll the busy flag. It speed up the communication, but I only had access to the first and third line. I then changed the E signal to be low between two commands. This is shown in the Samsung datasheet for the KS0066u. Bingo the display is working.
