I have a Y6 that I just got flying(seeduino mega, WMP & NK). Flew a few packs thru it with the 6-7dev w/o issue. This morning as I was heading out the door, I uploaded alex's change above. Trim in autolevel changed significantly(did not recalibrate the NK) but was flyable. Trimmed it with the fu...

Hi, And for people, who's transmitter sticks not centering properly, like mine DX7, it is good idea to add "Stick deadband". Easiest way is to add to the end of annexCode() procedure, something like this: // Deadband if (abs(rcCommand[PITCH])< 5) rcCommand[PITCH] = 0; if (abs(rcCommand[RO...

Oops, sorry

Centurian

I basicly made the same change a few weeks ago and see good results as well.

i think i am a dump... there is coming endless mistakes while i try to compile this... There should be nine files in the code folder when you unzip. In arduino, all 9 should open when you open any of them. Should have 9 tabs when you try to compile. Looks to me you're missing one or more files. Thi...

Do you get good data on ver 1.7?

Centurian

I tried the 529dev on a WMP only set up and it works fine. Uploaded the exact sketch to the WMP & BMA020 board and get no gyro data with or without BMA020 active.

Centurian

Hi, Thank you for this feedback. I think I know where is the problem for timing. (one time variable was renamed wrongly from uint32_t to uint16_t) At least this problem should be corrected in the last dev from today, it may have impact on other things. I tested this one successfully with: - a WMP o...

Hi, is it still the case with the release of yesterday ? Dev 5 26 appears to be much better. The frequency is down ~70-90%. I had to wait about 3 minutes to get 2 spikes on one gui screen as shown below. Previously almost every screen cycle had at least 1 and often as many as 3 spikes. Note: to mon...

Centurian

Anyone figured this out yet?? Obviously will have to be fixed in the next full release

Centurian

double post.. sorry... I get a time out every time I try to post here

Centurian

Ardo Happy, GUI sad... the dev code uses it's own GUI. I have a remzibi OSD and I don't yet understand how it's interfaced. If the GPS is lost to conect to the ardo, I'll keep the GPS. Is the plan to run the osd with the rx line from the GPS and the tx to the arduino?? I don't think that's possible,...

Hi, It's very strange because uncommented 2 #define for ACC should imply a compilation error (redefinition of the same function) Wow, I mistyped IGT3200 twice in the one post. I have only the BMA020 defined, the WMP autodetects, correct? With both the IGT3200 & BMA020 defined, there is no spike...

Centurian

Hey Alex, More strange BMA020 behavior... the bug fix http://wbb.multiwii.com/viewtopic.php?f=8&t=317 you posted worked fine until I commented "#define ITG3200" (I overlooked this line the first time I loaded the dev code). I'm running MWP with the BMA020. Now I'm getting spikes the ot...

Hi, I found a bug, I forgot a sign (in red here): ACC_ORIENTATION( (((rawADC[1])<<8) | ((rawADC[0]>>1)<<1))/64 , (((rawADC[3])<<8) | ((rawADC[2]>>1)<<1))/64 , - (((rawADC[5])<<8) | ((rawADC[4]>>1)<<1))/64 ); Thank you very much... problem solved.

Centurian

Hi, It's strange, This is typically what happen with a WMP entering sometimes in hardware reset. Did you enable the pullups in the dev version (by default they are disabled in the dev) Yes, my config file is in the first post, pullups are enabled.... the strange thing is it works fine in 1.7 someth...

The latest dev version is not working with my bma020. First two w/ scale set to 10, last w/o acc lpf scale of 1. Obviously getting some bad data.

Just want to make sure that the promini 328 can't run servo tilt with pwm sum on a hex. the pins are different, I assume it's a hardware issue, but just want to make sure.

Hey Quinton, Just took a peek, seems reasonable. Still using pin12 for wii power/reset.... alex's dev version has switched to pin37 which is my problem. Time to sleep here, but I think I'll try your code and see if I can get it working on pin 12. I assembeled the paris board you sent today to test t...

Centurian

Hey Alex, Yes, I'm using the dev version with octo support you posted above. I am not a hardware guy, I am really struggling trying to find seeeduino documentation that's understandable to me. The Pin 37 I'm using is next to the I2C bus on the photo I posted above (circled in yellow). It it the only...

Centurian

Hi Guys, Pin 37 does not appear to provide power to the nintendo sensors. It appears to me to be 37 in the code. The diagram at m shows the sensors powered by PWM Pin 12??? When connected directly to VCC on the I2C bus, works fine, get nothing on pin 37 as shown below. Any clue what I'm doing wrong?

Centurian

The seeeduino MEGA has an integrated FTDI. So, you can use directly the mini usb port of this board, the only change from the arduino IDE point of view is the COM port number. I think it's more easier to do this way. Yes, I'm using the onboard USB/FTDI and it works fine once I figured out the reset...

Centurian

Hi Alex, Thanks for the quick response. Got the code, not familiar with the layout(tabs in arduino.exe), but I think I got it. This is quickly becomming a log of my seeeduino progress: Compiles fine as is, comment promini and uncomment mega and I got an error. Solution is to choose the "mega&qu...

Hey Alex, I'd be happy to be the beta guy. All I really need are the pin assignements and motor writes. The relative motor calcs are easy. Looking at X8 (coaxial quad X) to start with. Not concerned with the GUI. I am an arduino idiot, will be using Seeeduino with genuine nintendo WMP & Nunchuck...

Subject says it all... wondering if anyone has code to support an octo on a mega? I thought someone had done it but I'm not finding it here or on RCG.

If not, who do I bribe????

Hi! I'm new to this forum. As I'd like to connect the different elements of my quadcopter these days, I was looking for further information (to be really sure about what I do) and came accross this thread. My question now is: Can I really connect the Arduino Board directly to one of the brushless c...

I've been working on a stabilized cam mount on a tri and to get cam pitch & roll trim thru the arduino, I had to go to serial sum to have enought RX inputs. Occasionaly I get a big jump(I'd say the value is off scale for a 1/20 of a sec or so, the servo appears to move toward it's extreme then j...

Centurian

I remember thinking a bit about this early on but have not revisited it... by the same logic should the rolls be divided by 2 to sum the absolutes to 1 as well or the pitches should be doubled to sum to 2?

I'll be playing with this to see.

Will be intersting to hear alex's take on this.

Centurian

Got it all working today...

Hey Alex, Great "hint" but it's not working.... how about another hint??? Hey, I just figured it out.. tell me what you think... It appears to me that rcCommand is only defined up to 4 (5 channels). The really strange thing is that the roll cam servo was being directly effected by the roll...

Centurian

Hey Alex, your camera mount went out Monday. I'm retrofitting my old tri with a camera mount and plan to use a PWM rx so I can run cam pitch trim thru the 328 arduino. My understanding is that 1.7 reads the additional channels but the cam code doesn't currently support cam trim. I havn't looked at t...

Centurian

One more item that may prove important.... need to find a way to limit "I" term cyclic "wind up" prior to take off or could have some ugly supprises!!

Centurian

Should work w/o modification other than the servo refresh rates. How well will be interesting. To make it work well, these things should be addressed: The arming proceedure should be disabled. May require independant servo directions/reversing for individual ccpm servo outputs. Servo refresh rate sh...

Sign change on "D" should reduce rcgroups traffic 5% alone

Need to remember how to get code off google now so I can check out the new level mode.

Centurian

2 things come to mind: Motor/esc/prop response is not identical between motors. Start swapping componets front to rear or side to isolate the unbalanced componet. If you move props, they all have to move and the signs in motor code need to be changed for yaw. Very good possibility it's a esc calibra...

Centurian

alex, I put the smoothing back in today and can't really tell a difference. Isn't this smoothing the result of a I2C Issue that will be taken care of in the next release? I do think that digital servo support is important, why refresh ESC"s at high rate and just let the tri yaw sloth along?? I ...

I plan to implement something like this with ranges for mode channel (AUX1). [1000-1300] [1300-1700] [1700-2000] For each range, customizable via checkboxes in the GUI: ACC/ no ACC baro / no baro compass lock / no compass lock Maybe another AUX2 RC chan if available with only 2 ranges to refine the...

Centurian

I dropped count to 3 as the GY401 outputs 270hz, seemed like the right value. I also removed the smoothing per Alex's suggestion as well. I would say it's almost as good as the gy clone at this point. I made a hat cam today and here's a little video I played around making: http://vimeo.com/19152816 ...

Centurian

@Centurian I'm not sure it is a servo update rate problem. You can try to de activate the smoothing function on yaw Just remove: gyroData[YAW] = (gyroYawSmooth*2+gyroData[YAW]+1)/3; gyroYawSmooth = gyroData[YAW]; It should improve the response, but with many glitches. I'm sure it's possible to supp...

Centurian

The "I" in the pid settings is "heading hold" What is needed is a faster update rate for digital servos. I'm using a cheap 401 clone w/digital servo on my tri and it's a vast improvement..... but I works best for me in rate mode rather than heading hold... the yaw response time a...
