MultiWii

Hello,

I am implementing flight in a volume for the multiwii. When the multicopter is getting out a cylinder, the failsafe alarm is running. My code is based on firmware 2.2. It had worked on one copter. I have a problem for making the buzzer working on another copter.

Bradwii has geofence, might be worth checking his implementation as it's been well tested.

Thanks. I did not find Bradwii as user name in the forum list members.

Thanks. Does anyone use buzzer with CRIUS AIOP V2 with multiwii 2.2 ? According to config.h, BUZZER PIN is on pin 8. But, it did not work.

I moved mine to pin 33

Is it a pad or pin 33 ? There is no pin labeled 33 on the CRIUS AIOP V2. There are 4 pad (32 to 37). In that case, you need to solder something on the board ?

For using a buzzer with CRIUS All In One Pro V2 with multiwii 2.2, connector to the buzzer must be soudered with pin 32 as in this picture :

You could just move it to pin 44, 45 or 46.. the crius define in def.h has cam trig, pitch and roll mapped to it, but if you're not using a camera or even all three of them, just remap it

Hi,

Here is my code for enabling an alarm when the copter is getting out a volume. I am using a CRIUS all-in-one pro v2.
It is enable by uncommenting the following lines
#define VOLUME_FLIGHT
#define VOLUME_HEIGTH_MAX 2
#define VOLUME_DISTANCE_MAX 10
It uses GPS for the distance and barometer for the altitude.

The code is based on Multiwii 2.3

Hi !
What is exactly the volumes you refer ? ( 100m or 1000m distance and 50m or 100m height ? )
Can you clearly hear the buzzer at 1000m distance ?
In future what is the goal if the copter is getting out a volume :
*Alarm via OSD
* GPS PH at the border of volume or RTH + Autolanding
* or other possibility ....

Hi Hinkel,

As you pointed out there are several possibility. The first goal is to provide an alarm for short distances (30 m) in order to inform the pilot he is out of the cylinder. The volume is a 30 m distance and a 50m height for example. The best alarm would be by OSD. For long distance, a RTH would be preferred.I am working also on improving failsafe.

Regards.

It is no more than 5 lines of code (assuming that you have active gps code)

I think code must be something like :

Two lines are enough



I will post all my code soon because it worked : RTH when going outside the volume.

Hi,

My code is available on github at https://github.com/Wadudu/MultiWii_Wad/tree/master/src

Your code is ok with vanilia MultiWii 2.3.
In the nav version I would rather change NAV_mode instead of box....

I would define two limits for distance.
First limit is defined as the distance from home, where copter will switch to RTH. A second limit is defined as first limit+50 meters. If copter reaches this limit, it will initiate autoland.

The first limit is working. I don't see why there should be second one. If the copter reaches the second one, it means the first limit did not work.

EOSBandi wrote:In the nav version I would rather change NAV_mode instead of box....

I don't see what you mean about. You are talking about these lines of code ?

waderic wrote:If the copter reaches the second one, it means the first limit did not work.

Wrong, it means RTH has failed and you have a rogue copter. That is probably what the limit is supposed to avoid. So I'd say a second limit makes perfect sense.
