Re: [Paparazzi-devel] Arduimu Integration Problem

[Rafael Espino Gómez]

Thanks Nicola,

This problem is present for me in MANUAL, AUTO1 and AUTO2. I'm going to buy inmediatly the new version with 16Mhz resonator and new sw and try it as soon as possible.

Regards,

Rafa Espino.

Hi Rafael,

Seems to be normal. My servos behave the same in MANUAL, in AUTO1/2 they're dead solid. Seems to be the PPM
Encoder, allegedly there is a new version out there with new hw/sw which solves this.

In the mailing list i found this
statement of the creator (hendrix aka chris e);

http://lists.nongnu.org/archive/html/paparazzi-devel/2009-09/msg00083.html

This seems to be the explanation, however
i never could be bothered to order a new one so i fly with jittering, no relevant problems at all.

Regards,

Nicola

Hi all,

Does anybody know about this problem?

Are these periodic pulses normal?

Regards,


Rafa.
