Hello,I sent an email asking about the following issues but wondering if anyone else in the forum has had similar issues.I have been experimenting with the basic power and degrees rotation motor functions. Here is what I have been witnessing:Medium Servo seems kind of ragged when the speed is reduced. Using an L293 driver board and PWM I can acheive much smoother operation.When I run the motor 90 degrees it only moves 77 degrees on average.I wrote a code to do the command 20 times and compute the encoder delta and then average after the 20 and after a few runs it resturns ~77 deg.If I adjust the PID param to increase the accuracy the PiStorm freezesI created a adapter cable to attach a Lego Power Function Motor to the PiStorm but cannot get variable power. No matter what I set for power the speed is always full speed. Any feedback anyone has, or similar experiences would be appreciated.
