retrolefty I tried using those methods but all I got was many errors during compiling. I've been programming in assembly for over 30 years. So I'm relatively new to C language. That's probably why I'm having so much trouble. What I'm trying to do is initialize a graphic LCD with a SED1330 controller in 8-bit mode. So I need to change all 8 bits simultaneously which is what the port methods do.
Well post an example of some code you wrote that doesn't work in the Arduino IDE, tells us what results you get or don't get, and let us see how you are applying the commands. Also tell us what arduino board you are using. I've used such commands in the past with no problem.
