I have been working with the B-168 the Pololu USB Programmer and Arduino. I am trying to get serial communication between the B-168 and my computer through the USB Programmer. I have connected wires from PD0 and PD1 to the respective RX/TX on the programmer. I am getting nothing. Anyone have any experience with this and could point me in the right direction?
Here are the errors im getting.
java.lang.NullPointerException

Did you move the mode jumper from the programming mode position to the USB-to-serial mode position? More info here.

Ok now I have communication established but I am getting something that looks like a ASCII return. I will keep working on this.
