Hi Synn, I'm happy you're making a brave attempt to use the new library! I think you forgot to set stepperDirCue_.clk, not sure if this is the only problem.
A few suggestions that can hopefully make your work more effective: 1. When you ask a question, please provide more information on *what* is not working. Just saying that the program is not working makes it very hard to help you. 2. If your program crashes, and in some other cases too, the logcat output (open the Logcat view in Eclipse or type adb logcat in the command shell) might have useful information to help you figure out what's wrong. Use it. 3. You can add your own log messages in your code, to help you figure out what it's doing, where it's stuck, etc. 4. You can use step-by-step debugging for even deeper understanding of what's going on. 5. Try to simplify your program as much as possible for isolating a problem. The program that you sent is a very good example for that! 6. Try to isolate electrical issues from software issues using an oscilloscope or a logic analyzer if you have them, or otherwise by testing your program against known-good peripherals (for example, replace motor drivers with LEDs, or first check your electronics manually).
