Hi all, I am trying to get an Optrex 4X16 LCD to work (HD44780) using the code from Peter Ouwehand's home page. The catch is I am using a 16C74A as opposed to the 16C84. Has anyone else tried this? I turn the circuit on and the first and third lines of the LCD are filled in with block characters, the second and fourth lines are blank. I am using the full 8-bit interfacing. FRUSTRATION!!!!!! Help me!! Help me!!!! I cannnnnn't seeeee!!!!! Thanx in advance Jay Mielke
