PIC WATCHDOG EMERGENCY what part do I need?

Unread post by Canary jam » 10 Aug 2012, 17:10

I had a LARGE shunt and broke my Cross Beam

After a straight forward repair 1st flight span out of control and dropped like a stone to leave me with the dreaded
PIC WATCHDOG EMERGENCY but full active picture and twitchy motors (normal)

Checked loads and loads of forums and went through this process,

1. Deleted Free Flight and reinstalled Same error
2. Broke down drone checked all cables, Same error
3. Installed drone control and reverted back software, same error
4. Checked in free flight all motors recognised and normal in the settings!

What do I need to order to get my baby up in the air again is it a nav board ,control board or something else or cut my losses and get another??

Cheers a frustrated Canary
:x

Per Parrot's answer on their forum... pic watchdog emergency means the Nav board or components on the Nav board are failing to communicate with the main board... please check your nav board connections and or send for repair

That's the ultra sound board... the nav board is the rectangle board that connects to the main board with hard pins... if you broke a central cross you might wanna look real good at those connection points because the damage may be on the main board side of that connection... this ain't gonna be a guaranteed fix... it's a tough deal to pin down that pic watchdog error

I am having the exact same problem. I wanted to take the whole drone apart before I ordered the Nav board. Upon disassembly I noticed the 8 prong connection from the Green Nav board to the main board. Tomorrow I get to try and solder the connections back on. I'll post updates to see if it works.

I would hardly say that my drone took a hard fall. Which makes me upset that they are built so cheaply.

Parrot knew exactly what they were doing that is why they have the parts available , they make more in part sales then in actual sales, very wise engineering! ;)

This is why I went to the QuadMod so much better control! :D

I also had the same problem when I broke my cross frame. In my case when I inserted the cable into the mother board it went under the connector(I think) and seemed loose but I thought it was ok. Checked the nav board end and it was a tighter fit. Then I knew mb end was wrong,removed and carefully re-attached it and was good to go.

The drones are very well priced for what they are.

Hi all.. I had my drone for a few days and flights, about 5 or so.

A gust of wind (or pilot error) sent it into a tree branch about 3m high where it proceeded to fall to the grass. Upon recovery, I noticed that one propeller shaft was bent. Replaced it, and powered up aaanndddd...

PIC WATCHDOG EMERGENCY

Appears on my screen. Took the thing apart, read all the forums and found a twisted/broken connection between the Nav/Motherboard 8-pin plug.

Now, my soldering skills aren't the best, so I got my cousin to re-solder the 8 connections to the motherboard. It looks like it was a successful job so I put it all back together aaanndddd...

PIC WATCHDOG EMERGENCY Appears again.

All four motor led show red but the bottom led shows green.
Any tips /thoughts on how to proceed?
Replace NAV board?
Replace Motherboard?
Run diagnostics?

Help me fly again

(Further to my last post...)

After soldering the 8-pin board connection :
I have the drone plugged in to the battery and it shows:
4 motor LEDs *RED*
1 bottom LED *green*

However, I noticed that the motherboard itself seems to get quite *warm*, almost hot to the touch.

What is all that power doing?

The thing will not take off, only showing the dreaded PIC WATCHDOG EMERGENCY message.

What does the bottom green LED indicate?

My drone shows:
-WiFi connects
-Battery 0 percent
-Both Cameras work and send images to my Nexus 7

Is something fried?
How do I trouble shoot this problem? Is there a program for diagnostics?


Grounded for now, *sigh*

PIC WATCHDOG means nav board is bad (or ultrasound board or white ribbon cable)... Green light means main board is OK and sending WiFi signal properly... Red lights on motors are just an extension of the PIC WATCHDOG EMERGENCY... showing that your drone will not fly in this condition with no nav sensor input... Main board does get pretty damn hot... This is normal ... 110 to 125°f is not any problem (as hot as a car's dashboard in the sun)

If you have done your solder properly... And you get a new nav board set... That should most definitely get you back in the air.

I have to say, It's kinda hit or miss on the whole "built cheaply" aspect. I broke a central cross from the Drone cutting out and dropping five feet to the garage floor. But, today I hit a telephone wire while flying and it cutout and fell at least fifteen feet right onto the rear left motor. All that happened was a busted gear and extremely bent shaft. It hit SOO hard too. I thought it was done for sure. I ran inside grabbed a gear and shaft and was back in the air in five minutes.
