NAZA code #490

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Hello, if you want to make this code like "NAZA",- make on all functions active 
- barometer with last altitude memory ...
I mean, when user not touch(stick info from console: +- 2) throttle button,- 
allways need to speed up or down motors by last barometer info(last known 
altitude).

Regards,
Elvinas LT

smscentras,
   It's not that easy I'm afraid.  If you check out the raw barometer data you'll see a "random walk" behaviour.  the baro readings can vary by more than 1 meter in less than 30 seconds.  I think DJI Naza is doing a lot more than just relying on baro.

After more tests, i think that they are including in the calculation engine 
speed (amps / volts).
