MultiWii

Hi TC, My board (naze32 acro) does not update, connect to base flight configurator or send data to my minimosd anymore. It does arm(green LED goes on when yaw right) and aux channels also work (red LED goes on when in angle or horizon, beeper beeps when switched on). don't know if it'll fly since qu...

I've found out some things(probably well known things, just not for me xD) The PPM outputted by the rx is low, then goes high for the pulse then low again. The PPM outputted by my 9x is high, then goes low before the pulse then high again for the pulse itself. (see attachments) I can imagine that th...

Hi, it seems like I am having a problem with my afromini 32. I've modded an frsky VD5M receiver to output ppm(put a diode on each channel and tie them together). I've connected this to the afromini and an logic analyzer. on the analyzer the channel 5 (from 5 channels) does change pulse width when I...

Like I said I soldered the caps, unfortunately the crystals I ordered are the wrong footprint so the big 16 MHz is still there. I have been unable to test it yet, will try this evening and then report. (to be honest, I dont think it will work now, any other ideas of what changes might affect my resu...

Hi, The SMD crystals just came in, so I'll solder them tonight(GMT+1), together with the caps. didn't think it would make a problem since the 2.1 version does work. will report my findings after that. changes I made to 2.1: #define RUSHDUINO #define VideoSignalType_PAL const char videoSignalType=1 #...

thank you for your help, this is what I tried: 1. Yes, I have attached a .zip file which contains a working project. 2. Nope, no data from GUI (this is a problem, I know, I just don't know what's causing it. I made an echo program and it works (at 115200) so the connections are right. 3. tried, no i...

I believe it is a rushduino indeed, and I am very sorry, but I have allready tried the above things(I did not use the buzzer since my multiwii has one, I did move the LED to the right pin in the software) but, unfortunately there is something going wrong in the GUI connection I think, when I write t...

Would like to donate you a few beers if I get it going.
can get these ones going: http://code.google.com/p/rushduino-osd/
But KV_team_osd just outputs black screen (no cam connected). I have made my board like this: osd-multiwii using this schematic: schematic

Can anyone point me in the direction of where it is going wrong?

Hi,

I'm nog using a baro(yet), also since it is a teensy it has the halfkay bootloader(wich only uses(like its name says) 0.5K)
Is the gps status visible in the GUI?

problem solved, solution found here: viewtopic.php?f=8&t=635&start=10

yay, servo works, stupid I haven't checked the pinout in the code...
Now, next question:P I would like to use the uart on the teensy for gps, is this allready implemented? or just on the arduino mega?

KoekieMonster.

Hi,

Yes, i have selected tri in the code. I also tried uploading BI, with this code, the servo did move so the pin's are connected correct.
I have also tried connecting a motor, didn't work.

Hi, I am having problems with my teensy tricopter. I am using ITG3205 gyro, ADXL345 ACC and HMC5883 MAG. and a teensy as controller. the problem is that the yaw servo doesn't move. all 3 motors work fine, just the yaw servo doesn't. I have verified that the output is wired correctly by using a demo ...

Hi, I've followed above pinout diagram for teensy but can't get my yaw servo to move. all 3 motors work, just the servo doesn't. I'm using gyro, acc and mag. and using dev build 20120504. I am using HWPWM6 and I did uncomment the #define TEENSY20. does anyone know why my tail servo isn't moving? Koe...

I have just received the GPS chips, tested one of them and it works like a charm, used the teensy as a usb-serial converter and 10cm of copper wire as antenna. used trimble gps studio to test.
Now I'll just have to make it work with teensy and multiwii.
Thanks.

are these usable for gps hold and gps gps home functions on multiwii?

I got one of those with the l2g4200d on it I'm trying to set it up now. I would still be banging my head against the wall if it wasn't for Katch and his code. What I have noticed tho is this imu is not as intolerant of vibrations as the wmp and nunchuck combo. and by "not as intolerant of vibr...

I gave up on the NK. Ive ordered a breakout baord with the HMC5883L compass and the ADXL345 accelerometer(€12,75) A friend of mine ordered a breakout with the L3G4200D gyro, the ADXL345 ACC, the HMC5883L compass and the BMP085 barometer (€26). So a lot cheaper then the 9DOF from sparkfun($99.95). Wi...

I am using 3v3 allready. I cant just use the chip since this is analog (and not I2C). I didn't find a picture of one on the thread, but thanks for the link, saw some cool things in the pictures(a 3" quad, exactly what i was planning on building) I found this thread : m wich is exactly the probl...

I do know how to connect it(silkscreen on pcb) but it just simply doesn't work.
The accelerometer itself is analog(it looks analog) so I can't remove the black blob this time.

Well, the WMP problem is solved:) saw a post somewhere of someone who cut away everything except the gyro itself. This made me realize that the rest of the components are not needed and may interfere. the IC labeled "CH0901" in this pic (not my own photo) was just a black blob, so i cut al...

I'll go experiment a little more, if this doesn't work i'll order a new wmp and post it here.
Thanks for your help.

I've tried reading it using an mbed (www.mbed.org) but that failed too, it did acknowledge the adress and register adress, but only returned 0 values... So reloading the sketch with default setting doesn't solve anything if the gyro doesn't respond. right? Does anyone have any idea of why the gyro d...

I connected the logic analyzer to the place where the pullup resistors were, so I'm measuring that only a few mm away from the gyro.

KoekieMonster.

nope, I have tried with and without nunchuck and tried switching SDA and SCL (even though i was very sure they were right) several times.
cycle info is about 4400 if I remember it right.

I'm trying to build a multiwii controller with the teensy. I've wired it according to this pinout: http://www.multiwii.com/forum/viewtopic.php?f=8&t=635&start=11. I'm using the dev version (since this is the only one supporting the teensy). The sensors I'm using are the WMP from dealextreme ...
