MultiWii Dynamic PID Attenuation mod

If you use the MultiWii in an airplane, you may need to change the PID attenuation not via the THROTTLE stick position but via an AUX channel so you can choose in a dynamic way the PID attenuation for the different flight conditions (dive, high speed pass, slow fly, strong wind and so on) regardless the throttle stick position

Here the original MWii code for TPA (file MultiWii_2_1)
Code:
 
  #define BREAKPOINT 1500
  // PITCH & ROLL only dynamic PID adjustemnt,  depending on throttle value
  if   (rcData[THROTTLE]<BREAKPOINT) {
    prop2 = 100;
  } else {
    if (rcData[THROTTLE]<2000) {
      prop2 = 100 - (uint16_t)conf.dynThrPID*(rcData[THROTTLE]-BREAKPOINT)/(2000-BREAKPOINT);
    } else {
      prop2 = 100 - conf.dynThrPID;
    }
  }
Following my Dynamic PID Attenuation mod (file MultiWii_2_1)

Code:
 
  #define BREAKPOINT 1050
  // PITCH & ROLL only dynamic PID adjustemnt,  depending on AUX4 value
  if   (rcData[AUX4]<BREAKPOINT) {
    prop2 = 100;
  } else {
      if (rcData[AUX4]<2000) {
      prop2 = 100 - map(rcData[AUX4],1050,2000,50,100);
    } else {
      prop2 = 100 - conf.dynThrPID;
    }
  }

*** ATTENTION ***

The code has been tested on the bench only!

This is my 3rd attempt to a very high flight with the GAUI 500

1st attempt 400mt ASL
2nd attempt 550mt ASL
3rd attempt 832mt ASL

The weather was very windy and the GAUI 500 was barely able to fight against it.

During the descent I've reached a GPS speed of 82km/h!!!!

Here a video with the new OSD firmware version by Remzibi (2_22)

Test with MultiWii 1.8p2 AHI w/Remzibi OSD fw v2_22 (1 min 23 sec)


In attachment the MultiWii 1.8p2 modificed code for AHI display on Remzibi OSD

**** WARNING ****
THIS IS A TEST CODE. USE IT AT YOUR OWN RISK



MultiWii_1_8_patch2_OSD_330_OSD_NEW.zip

Remzibi OSD needs firmware 2_22 and a little hardware mod Check the following links

Hardware mod
http://www.rcgroups.com/forums/showp...postcount=3661

Firmware 2_22
http://www.rcgroups.com/forums/showp...postcount=3698

The connections between MultiWii and Remzibi OSD are very simple:
  • Arduino GND to RemZibi GND pin (video pins side)
  • Arduino Serial TX to RemZibi I4 pin (video pins side)
The AHI display is activated/deactivated with full elevator & left aileron sticks commands (motors disarmed)

You can enabel/disable the OSD support in config.h like other MultiWii's features

The code is very simple and needs some more cleaning.

It's just a proof of concept for AHI display on MultiWii

Ciao

I'll post a video later

Next steps: cleaning the code and integrate the parameters setup on the OSD screen so you can change the PID values looking at the monitor or goggles
