Hi, What is the easiest way to only deactivate ROLL autolevel. PID for ROLL & PITCH are separate, but the PID for LEVEL is for ROLL & PITCH toghether. What i want to obtain, is that only PITCH is returning to its 0-reference level not the ROLL, so basically gyro only PID for ROLL. Thanks, manu

Yes, 2.2

Are the values, you are trying to set, for RC Rate and Thr Mid different from 0 ?

Spot on, when Thr Mid = 0 i can't save to eeprom, when <>0 (eg:0.01) it works!

Hi Ezio,

for a MultiWii 2.2
I have the unlocked version 3.94.148 on a Asus tablet. I can't save (to eeprom) the PID values, all readings are correct and working.

Still have this question:
Are ALL Gui settable parameters settable in the 3 profiles? In other words, can I have 3 sets of all PIDS/rates/… etc.?
If yes, how to set them via the gui, what is the sequence to save the profiles.
This would be wonderful.
Thanks,
Manu

alll

I know how to change profiles (0,1,2) via stick, but could not setup different profiles in the GUI!
and I still don’t know what parameters are or can be part of a profile?
manu

alll

Yes, this is what i want to achieve with "multiple profiles"

Via aux switch (inflight or if this is not possible unarm/arm), have different rates, and if possible PID too!
Is this is how "multiple profiles" works?

thanks,
Manu

In original release 2.3, are only these values : int16_t accZero[3]; and int16_t magZero[3];affected by MULTIPLE_CONFIGURATION_PROFILES in readGlobalSet();?

I still don't get the "big advantage" of using MULTIPLE_CONFIGURATION_PROFILES .

Hi, I was wondering what GUI-settable parameters are included in the “MULTIPLE_CONFIGURATION_PROFILES”? The usage is not straight foreward. Is there a way to have different “rates” selectable via tx-switch? (or inflight adjustable via proportional channel)? Manu PS: the new2.3 yaw PID implementation...

Maybe i am not aware of latest implementations, ... What i mean is that activating "main functions", mutually exclusive, like command NAV or PH or RTH or LAND or ... it should do it on demand without priority, you can't do 2 or more at the same time? I don't see why there is a need for pri...

Just quick thought: AUX1 Low : manual (gyro/acc only PID) Mid : Attitude (software activates auto level and all sensors to do that) High : GPS (software avtivates GPS and all other sensors that are needed AUX2 Aux1Low Aux1Mid Aux1High Low Normal Normal Hold Mid Mag Acro Nav High AltHold AltHold RTH ...

alll

Can't you program it as a "trigger", when "on-off" = "off-on" triggers the function MISSION, PH, RTH, ... whatever the previous function is, PILOT is still in control and not the "pre-programmed" logic.

Keep it simple
manu

That was the purpose of I2C_GPS_NAV, and is abonded... sad IMO. Now all is separated in code files, but treated by 1 cpu.

If GPS needs IMU information, then it is another story.

Alternative:

I feel a little bit sad, when others send posts with: "Everything is perfect now, but I will not give you my values, because my copter has another configuration than yours!". So, I hope, my values can help others. It's just for orientation, how to tune your PID values. Chris Thats me! ......

Hi,
What kind of filter is currently applied in ver2.2 for the mag filter?

I managed to get rid of violent mag spikes at hoover, now there is still a constant ripple (GUI). Can this further be filtered?

Hi,
What explains the “circling” effect while tuning GPS position hold PID’s. (quad starts to make larger and larger clockwise circles around the pos –hold position)
Is it possible that it comes from the vector calculations where the calculated projections are distributed on a “circle”…
