Hi Jason,
I was excited to finally see the PID fix so my robot doesn't keep bumping into walls and stuff ;-) but unfortunately, as soon as I installed the 1.2.3 library, my C# application started throwing "divide by zero" exceptions. If I go back to 1.2.2.4, my application is happy again...
Thanks,
patrick

| Hey Patrick, Hmm...Nothing that was changed between 1.2.2.4 and 1.2.3.0 involved anything w/ a divisor, especially w/ the PIDMotorController. Could you please either post your code, or try to see where the exception is being thrown? That would help me further figure out why you're getting the DBZ exception. Best Regards!

Hey Jason,
Good news--it wasn't the fault of the new SerializerLib. I *thought* I hadn't changed anything else beside the library but in fact, the day before I had installed a new version of RoboRealm and didn't realize they had changed a string format in one of the variables. It was pure luck (or bad luck) that I didn't hit that bug right away. The new version turned a string variable into a zero instead of a positive number in one of my x divided by y statements and voila! In any event, all's well that ends well--and Pi Robot is no longer running into things thanks to the nicely fixed SerializerLib. (-;
Thanks again,
patrick
