Sorry. Quantization error is the "stair step" error you get when converting analog to digital due to the finite resolution of a digital value.

If you graph current draw vs. time, the area under the curve represents capacity. You can think of that area as a bunch of rectangles side by side with a height equal to the ampere value and an infinitesimally small time width. Since the samples are at finite intervals, you have to settle for larger rectangles with a width equal to the sample period.

Does anybody know of a good, cheap PCB fabrication place? I'll need a backup in case the laser printer toner transfer method doesn't work.


Hi TheBum
I have been using Seeed Studio for work and personal PCB manufacture for a couple of years now. Very good value and about 10 day turn around.

Cheers
Magnus

Hi...i am a new user here. One thing I will say is the GPS accuracy reported in cm is absolutely fantastic and makes PID tuning a lot easier. I never takeoff now until I get an error below 90cm or better.The distance to next waypoint is cool and really makes you appreciate the telemetry. I can't wait for the DIMU to be released so we can try the other great features that CAN brings.
