Nice work!
I ordered mine a week ago but not due here till mid April.
I hope to have it display MWs’ Home coordinates after FIX.
With this and a GPS phone, HOME location can be checked easily.
Again, good work Howard!

Wayne

Thank you Alex and all.
Let March 25 always be known as 2.0 Day!

Wayne

Darn MelihK, I ordered with Ohararp and Flyduino a couple of days ago.
I am glad to see you added some mounting holes.
Lack of mounting holes on your serial module kept me from ordering it.

Wayne

Good idea Christoph or maybe reset each time we arm.
To do this we would have to separate the LED functions, one for armed/tilted the other for Fixed.
Or a new flash rate for Armed/Fixed would work too.

Also I noticed that MW does not stop flashing the LED after 3D fix is lost by the module.

Wayne

Fritz I wish I could help but I ussing Serial GPS... My MW Home never seams to be where I am. Off by a few meters to 30-40 or more at times. The first Fix I get always is way off and resting MW after HDOP is down around 1.0 helps a lot. In an effort to reset Home I did write a few lines and get a bu...

Wayne

Welcome back EOSBandi!

Wayne

Pin 13 already has an LED toggle. I cannot get a lock inside today to see if it is on when FIXED.
Arduino Tutorial has info on pin outs.
I was looking at the one for buttons today as I would like to reset 'home'.

I got a fix and pin 13 flashes an LED when locked.

Wayne

Alex you are the man!
No more MEGA freeze!
Now if you could do something about the forcasted rain and snow we are to get here this weekend......
Thank You!!!!

Wayne

Thank You Fr3d.
I have found MiniGPS, downloaded it and am now looking for a pair of 33ohm resisters and an old USB cable.
I’ll get this to work yet!

Wayne

My HK/Apache GPS module seems to lock then drift, sometimes 100M or more from MWs home position. This may be why my MEGA2560 is freezing after GPS lock with 2.0.PV1&2. (dev_20120225 does not freeze) I’m going to wire in a LED to tell me when MW has GPS fix_Home established and try changing GPS_n...

Wayne

This morning with 2.0.PV2 loaded and without MAG/BARO, I froze a minute or so after GPS lock. I did however, without unplugging, hit the reset button and loaded dev20120225 into it WHILE I still had GPS lock. I opened a new session of MWWinGUI. I see that I have lock onto 6 satellites and have a dis...

Wayne

Thank You Alex for 2.0.PV2!

Wayne

I am in the market for a GPS module as my HK/Apache module may or may not work. HK/Apache uses GTPA010 and the same chipset as the Flyduino’s FMP04, HK/Apache is just smaller. I found FMP04 for $25 but I do not want to buy the same freeze problem again. nhadrian, what Locosys GPS module are you using?

Wayne

Weather outside today was too good to be inside chasing my freeze issue so… I unplugged my HK/Apache GSP module so I would never GPS lock/Freeze. With GPS and all sensors uncommented I flew two sets of batteries. I rotated the sets in so it did not reset for almost 15 minutes of flight time. Not one...

Wayne

Out of memory. To test comment out all sensors but gyro and disable all other unneccessary features. Today’s test includes changing from Tri to Quad. I unplugged the servo, uploaded all sensors/defined QUAD_X. It ran here inside without GPS lock for over five minutes. Outside I get freeze after GPS...

Wayne

That’s it, I have GPS lock and no freeze. Now I’ll bring back BARO and MAG one at a time, MAG first. Thank you Hamburger! It freezes after a few seconds with only MAG and takes twice as long to freeze with BARO only. To check now I’m going to take them both back out and see if it ever freezes. Then ...

Wayne

To see if the buzzer stuff was making my MEGA freeze I commented in front of the LED and BUZZER under GPS. I put // in front of anything that hung up when verifying. Loaded it, looked good in GUI but no change, freeze just after GPS lock. I’m looking now to see if MW might be changing the baud of se...

Wayne

I know that headache too. Last evening and into the night I looked at the code. I would comment out lines one at a time that had to do with GPS and if it would verify I would upload it. I have yet to find the line that freezes MEGA after GPS lock. I don’t think it’s the frame decode as it works in d...

Wayne

HK/Apache GPS report: I loaded 1.9.2 into my MEGA2560. Configured Serial 2 and 38400 Baud. Calibrated ACCs and MAG, took it outside and in under 30 seconds I had GPS lock and no freeze! Ran inside plugged into 1.9.2 GUI and can see that I am 40m West of home and the number of sats. is 5!!!! Now to s...

Wayne

OK it only freezes when the HK/Apache GPS is plugged in. I did let HK/Apache stop flashing outside while serial two was unplugged. Then I ran inside hooked MEGA to WinGUI and see that everything was working UNTILL I plugged in serial 2. When plugged in the satellite in WinGUI went from red to green...

Wayne

It may be my HK/Apache GPS....
Before it freezes, on the WinGui I can see the number of satellites change.
Just after it turns green it has 3 or four sats. fixed and shows dist. to home, once 5M, once 0M.

I’m going to go and barrow the laptop again and see if GPS is working without SpekSat defined.

Wayne

That’s it. I have been flying SpekSat from day one. I know SpekSat works.
I (MEGA) freezes after GPS Lock only when I uncomment ‘//#define SPEKTRUM 1024’.
Its not the hardware as I left SpekSat plugged in.

Wayne

Update… I have reloaded a fresh copy of 2.0.PV1. Mega still freezes at the moment GSP lock is acquired. Loaded MWWinGUI into a friends laptop this morning. I can see that it is finding satellites, 3, 4, 5 once. The moment the GUI satellite turns green everything freezes. I’m now going to wire up a 3...

Wayne

On my MEGA 2560 controller I have wired in my HK/Apache GPS antenna to 3.3V, Gnd, and Serial 2. When I set the Baud rate to 38400 I can see ‘PKT’ flash in the new GUI so I’m thinking its working. No other baud rate makes the ‘PKT’ flash. I cannot hook it to a computer outside but when the stops flas...

Wayne

I loaded dev_20120219 onto my new Radio Shack Mega2560 yesterday, aligned the ACCs, Gyros and MAG. This morning I got a chance to fly it. Everything was as expected and the new altitude hold is unbelievable. Even in today’s cold wind the BARO held, even with a little forward flight. Thanks to all th...

Wayne

Works now!
Thank You.

Wayne

Went in first try.
All working so far, I can read/write.
Art.horz. moves as does Acc/Gyro values.
My graph is flatline.
1.9 - WIN7 32-

Thank you for all your efforts.
Wayne

Wayne

Dimitri, the WM+ is Gyros only. You say you have ACC values, do you have ACC in Green in the GUI? If so you have an ACC of some kind and you just have to assign switches to turn them on. Without ACCs the copter graphic in the GUI will not move. If the ACC is not green, check to see if there is any s...

Wayne

Your motors are turning almost three times to fast for a multicopter.
Try sub 1000KV motors. 750KV with 3 cells works best for me.

Wayne

Are you using counter rotating props? If not you have to tilt two of the motors a few degrees.

Wayne

I had issues with HF but with the post above by Noctaro all fixed now.
Thank you!
Wayne

Wayne

I would like to try the new HeadFree option on my Paris V4 quad and have a question. What are the hardware requirements? Do I need to have GPS working and a Mag or will Mag only work. I have downloaded and have working Arduino 1.0. I have also un-zipped the latest dev but do not see a change file. T...

Wayne

All answers are in the MWC UAV Wiki: m Its a gold mine with pictures, of almost every copter you can setup! The BEC/ESCs BEC thing is explained there too. The board has a place for the cap. You’ll leave the bridge open and power the servo with only one ESCs BEC by removing the red wire from the othe...

Wayne

I too have 1.9 working best it ever has. When 1.9 came out I was one with the dead copter slow blink. Alex fixed it but it was said to be a hardware problem workaround. I could fly the fix but it just was not right so I went out to find my hardware problem. I have…Hex6X, Paris V3, WM+, NK, Baro w/LL...

Wayne

Alt. hold is working OK for me. Stock PIDs too. I wonder if most problems are with how the Baro is mounted. Mine is double foam taped to the underside of my Paris Bd. The board is mounted inside a firm plastic sandwich container, lid down. The only holes in the container are two 10mm holes in the li...
