I don't think they look backwards. Seems correct to me. The AH should lean left when the quad banks right, that's how it works IRL (tilt your head to the right, the horizon line moves to the left). Assuming the front of the quad is the side facing the screen and we're looking at the back (and regard...

Doesnt appear you have java installed, if you do that error is telling you it's not where it's looking for it. You can either install / move JAVA [move it to where it is looking would probably be easier than changing where it's looking for it] or you could try out WinGUI which isnt JAVA based (note ...

Cereal_Killer

Have you verified all your sensors are defined correctly? Watching the flight gauges in the GUI the AH points up with up pitch, down with down pitch, left with right roll and right with left roll?

You've watched the raw data coming in on the graphs to verify gyro / ACC don't conflict?

Cereal_Killer

Can anyone confirm if the bootloader on these HK dedicated FC boards is just the standard arduino bootloader? Assuming it is you'll be able to flash a new bootloader to this one once your new one gets there. Never thought of a missing bootloader before threw all this cause it's somehow got working M...

Cereal_Killer

Have you verified you physically have power at the WMP? Have you checked for dead shorts everywhere (between + and GND and between the data lines [to eachother] and between the data lines and + and GND)? D12 can either be used to power the WMP or as an AUX2 input but you have to set it in code, you ...

Cereal_Killer

Bricked, no, missing the bootloader is a possibility tho. It doesn't use it to talk to the GUI, only to upload new code.

When you push reset what does the "L" LED do?

Cereal_Killer

I will watch your videos and try to address your actual problem a little later today but first please see this thread and read threw it, he was trying to use a arduino / DIY radio setup and we discuss why that's never a good idea. Not to be hard on you either but a DIY radio setup is NOT appropriate...

Cereal_Killer

Hey guys, about a week ago my tricopter crashed and I couldnt afford a new PLA 3D printed body so I changed over to a scratch built / DIY style body. I got everything back together (using all the same parts) and plugged it into the GUI to check the RC inputs and general stuff before flying (even tho...

Cereal_Killer

"Pull-up's" are pull-up resistors from the two serial lines to 5V. If neither the arduino nor the WMP have these you'll need to add them in your wiring. i2C bus requires 10k pull-up resistors on both lines. Maybe one or both of your boards already has them, just throwing out ideas. Was the...

Cereal_Killer

Ok it sounds like you are getting a full 2-way connection, just to verify, both the RX and the TX LED's on the board are flickering when you're connected to the GUI right? If your i2C error count is rising there's a good chance you're either got the SCL and SDA lines reversed or you have them wrong ...

Cereal_Killer

What was your i2C error count doing? climbing or steady @ 0 or what? Didnt think about this but with a quad you may not have a servo tab at all unless you have some type of servo connected, either a camera servo or for some type of landing gear. Under the settings tab do you see the battery warning ...

Cereal_Killer

Close comms and reconnect.

If the servos tab doesn't come up it didn't initialize all the way. It usually takes a few times IMO.

Cereal_Killer

Hm, just to verify you have both board and processor selected correctly in the arduino IDE. If it were me I would try to flash a sample sketch (like "blink") to the FC but if that worked and then you couldn't reflash it with multiwii I'd feel like it was my fault. That's why I asked if you...

Cereal_Killer

I know nothing about RasPi (I've got one ordered from China, planning to make it a Linux desktop computer) but the communication back and forth shouldn't be an issue. The thing that concerns me is you say you're wanting to communicate with it over wifi, that's really not a good idea, even tho it's t...

Cereal_Killer

It's doubtful it's a spring-bar issue. Would you be willing to buy an arduino? It'd be $3-4 shipped from eBay from the U.S. I'd offer to send you one (I buy them in 5 packs and have plenty) but I'm afraid it wouldn't help you much cause I buy the ones with on board USB-> UART converters. You'd want ...

Cereal_Killer

Hm, I never got an "post to long" error when posting my entire config.h file in code brackets. Without your file there's almost nothing we can do for you. Try posting the code (in code brackets) in a reply. Other than that, some of the easiest stuff- are you running an OLED / LCD display? ...

Cereal_Killer

No, the arduino IDE and AVRDUDE neither use JAVA, it's only for the GUI. Since your GUI is working you're good to go on JAVA.

Do you have another arduino you can try to upload to? This will tell us if it's a computer issue or a FDTI USB->UART and/or your FC board issue.

Cereal_Killer

Update / solved- wasn't a MW / code issue, the display started getting more and more dead lines so I tried it with a stand alone arduino and the same I thing happened and now it's only got ~10 lines left on the bottom. If this happens to yours it's definitely the display going bad.

Cereal_Killer

Ok this is actually something I've been wondering about a while now- how does the OSD get it's info, does it read the individual input's that the main FC is getting as individual raw data or is it being sent all the params in packets via serial data (i2c / UART / other)? Back to your question, do yo...

Cereal_Killer

Yes that's [usually] correct (tho you can adjust as needed). I think you missed my edit to my post a few up- where are you reading this voltage? In the GUI or on an on-board display? Do me this favor, just so I can stop asking about your settings please paste this snipit of code over your code (this...

Cereal_Killer

That doesnt seem like the wind to me man, could you post a video of it flying stable in calm conditions? I was expecting to see it get blown around and maybe a slow oscillation down to the ground, to me that looks like a bad tune overall causing vortec ring state leading to a straight down fall from...

Cereal_Killer

Ok and then you're changing the nominal voltage to match ?

-again sorry for simple questions. Just that I've been there & done that on to many things before so I wanna cover all the bases before looking deeper ya know.

Cereal_Killer

[Probably a dumb question, you seem to know what you're talking about so I assume you're doing it right but...]You are setting the real scale in the code right? Not just the nominal scale in the GUI / on board display / Bluetooth?

Edit:
And you're reading it where (a GUI or on-board display)?

Cereal_Killer

Looking great man! What props did you go with? I've always used GEMFAN's but there are plenty of good options that dont cost to much. Yes you can definitely solder all your connections, that's what I always do. There isnt really a good way to test motor direction, just solder [guessing the order] te...

Cereal_Killer

Are you using 1% resistors? What banding do they have? Sounds like you can get away with adjusting the values a bit to make the output 1-4v, you'll sacrifice a bit of accuracy as it'll scale differently but I think that would get you going.

Cereal_Killer

What code changes exactly are you using to change the vbatt pin assignment? Also what lines have you uncommented for the standard vbatt setup? What values for the set points and the main offset? Do you have a bench top power supply? It would help if you could dial up and down the voltage and feed it...

Cereal_Killer

Hey guys, last night I was doing some soldering adding in some LED's and stuff and today I went to fly and noticed my OLED looking strange. It seems to be missing about half the pixles, I cant tell for sure but it looks like every other horizontal line is missing. I've went over all connections and ...

Cereal_Killer

Just wanted to post that I pretty much agree (and couldnt have typed it as well myself) with FSDrone. FYI my endpointes all needed to be set from -110 to +125 (I tried -125 but that made the value on multiwii so low that it actually triggered failsafe to kick in just by moving the stick down). I als...

What MCU is on the FC you're using? What pin are you hooked into?

Cereal_Killer

Reading your OP I think you may be confusing the config.h header file (part of the sketch) with the configuration tool (the GUI). They're unrelated. The config.h header file is where you make most of your code changes and do the initial setup. AFAIK FSD is correct that there's no way to really "...

Cereal_Killer

When you trim the acc you don't do it per motor, it's an overall thing. This is why you have a drift with no stick input. You'll need to experiment (one click at a time) till your motor bar graphs are all even when only throttle is applied. Not sure what you mean by the last question, auto level is ...

Cereal_Killer

Thanks for that video! So everything looks good however right off the bat I notice one thing you'll definitely need to correct, you need to trim your ACC left several steps. Refer to this video (not my video) to do that. As of now you wont get a steady hover, it'll want to move [left I believe] and ...

Was the GPS packaged in with the FC? If you dont want to or cant make code changes to the FW (the "sketch" in arduino language) then multiwii is not for you. Nothing against you at all, as an engineer I make my living off the wants and dreams of end-users and their plug-and-play product ne...

I think before we try any more random guessing I'll wait till you get back to all of th...

Cereal_Killer

I'd still advice, especially with current public opinion of "drones" that you use a real, proven radio system, if for nothing more than liability concerns... Are you at least using PA'd NRF modules on both the "tx" and the quad? Back to your problem, I do think the input's look o...

Cereal_Killer

Yes that's to be expected, you ABSOLUTELY MUST change the arduino sketch, you cant setup this kind of stuff just from the GUI.

Have you downloaded the arduino IDE and the source code? If so find the MW arduino file and open it, switch to config.h and enable your GPS equipment and set the baud rate.

Cereal_Killer

Can you post some more details on your "radio"? Is it PPM SUM or a standard receiver? What radio is it actually using (just guessing an NRF24L01+)? Why did you want to do it like that, just to save money? You can get an orange Tx or a Devo 7E for around $65 and a <$10 DSMX rx and be WAY BE...

Duhjoker could you make one more video, I have a theory (but I dont want to type it incase it's wrong, I dont want to add useless info and confuse you)... What would really help us is if you can show your GUI screen (with the RC data up on screen) and then also show the RC sticks at the same time an...

Yep it tries to go in whichever direction I send the stick but yea it's flipping. Ok so I've got something hooked up wrong. Ok I used the reciever on a 4 channel Foamie and one through 4 go like this Ch1== ailerons/rudder have set on quad as Ailerons Ch2== elevator. " " Elevator Ch3== thr...

Also when lifting the throttle from the bottom and giving the motors juice I noticed that they are all pushing the quad downward sending the thrust upwards instead of lifting the quad. This tells us either your motors are spinning backwards or you're using the wrong direction props. What radio and ...

When it's working incorrectly I'm confused on what's happening- is it making a continuous single tone or it's continuously beeping beep/silent/beep...?

Cereal_Killer

Well still having problems, now when I take off it starts to spin and full opposite yaw doesn't even slow it down. I'm using two CW and one CCW prop (one each up front and another CW on the tail).

I'm thinking maybe my two Z axis' are still mismatched?

Cereal_Killer

Hey guy's, noticed I updated the thread title and OP. So to answer my own question NO THE MODEL WILL NOT FLY IF THE LITTLE ICON DOESNT SHOW YAW! Well it'll fly a little bit, but not correctly or controllable at all. I was able to solve it tho and get it flying by changing forced sensor orientation. ...

Cereal_Killer

Thank's both of you for the clarification on that, makes total sense and I didnt think about that aspect. I'm waiting on a new DSMX receiver before I can fly it so I've been thinking back to the second issue again. The icon still isnt showing yaw movement. Here's another thing, it takes 6-10 times f...
