alistairr: The gps_ins_vel factor (actual "0.6", was 0.7 before) describes the internal weight of the speed measured by acc (acceleration over time) and the measured GPS speed for each axis. Since I altered the scale of the acc from 8G to 4G it MIGHT be necessary to lower that value (do it...

@alistairr: THX for your feedback, but concerning the naze5 buzzer stories (I don't have and need one) there must be an error somewhere. Concerning the GPS the pre2.6 might require a slightly lowered gps_ins_vel, I can tell you more on this when that gps stuff incl. WP is done and I have the chance ...

That is reality.
Prop loss can be avoided completely.
BTW: If someone wants a very crash resistant quadrocopter I would suggest to go for a Walkera Ladybird....

@Neu: That video looks awful. Probably pre 2.6 is not naze 5 compatible. Sorry for that but it will take some time before I will look at the naze5 stuff again. @rortega: There are several tuning options. Please look in the parameterlist in config.c and the readme - you will find useful information t...

Oh, well what was f** up shit from the beginning to the end. Remember what a sonar can physically do and look at that code - it makes you cry.
That "fusion" is gross sh't. Remember: Sonar gives you RELATIVE distance - never absolute hight. So wait another 2 years until mwii understands that.

Crashpilot1000

What a sh** that your copter suffered severe damage, damn.
The 2.5 is here: http://fpv-treff.de/download/file.php?id=6257

Crashpilot1000

Hopefully the crash was no major damage! Please stick to 2.5 for GPS, I haven't tested PRE 2.6 not yet on GPS, but already made some changes there. Motor PWM imbalance is a matter of the frame, center of gravity and stickinput. If you have still pre2.6 on board you can do a normal hover (in the back...

Crashpilot1000

@Paccik: Well I haven't been testing gps functions in pre2.6 because it's still in the works (splitting gps code up / rearranging). 2.5 is tested... @Hinkel: Thank you very much for sharing the results of your curiosity! I didn't expect that result. Maybe there is a chance we can reasonably combine ...

Crashpilot1000

Hi PacciK! Yes rebuilding is a pain! I once crashed into concrete (copter mostly wasted) with an emergency motor shut off done by me to prevent other damage - completely my failure.. First of all: test in appropiate hight, because you can always oversteer gps stuff and regain control. High grass is ...

Crashpilot1000

I rechecked the limits. I see no way how a command greater than the gps_maxangle could make it. BTW GPS modes are naturally not supposed to work in horizon mode, that's why it is turned off in that case and angle mode is activated so that shouldn't be the problem with your setup but it may be safer ...

Crashpilot1000

After a few seconds ...say 10sec ..... WHOOP !!!! a HARD LEFT all by itself, and WHACK on the ground inverted. Well, since "gps_maxangle = 25" is the preset it is not possible for the gps controller to send more than 25 degree tilt to the level controller (needs to have non wobbly pids, o...

Like always in mwii the boxes turn green when the function could be activated. Probably not enough sats in your room??
Cli command auxset is described (with example) in the cli. That original was non human readable and just an awful waste - probably still present in BF.

Hi ! Just a stupid noob question in Harakiri in config.c the parameter cfg.D8[YAW] is not define for eeprom write, but in mw.c the parameter cfg.D8[axis] is use for the PID Controller, axis is going from 1 to 3 so is there not a possible bug if the cfg.D8[3] is reading value from cfg.D8[PIDALT] in ...

Crashpilot1000

Well if it is a kit it must be constructed and tested that every sensor works flawlessly with it(Mag!) otherwise send it back to the shop.

Crashpilot1000

Have not tested camtilt or altered rx channels, that is unchanged from older orig. BF so i expect that to work. Reading the readme.txt is not your business ????????????????????????????????????????????????????????????? I will not comment on stuff that is already in the readme. Using some gui instead ...

Crashpilot1000

If you are planning to use the onboard mag for gps, it will never work and randomly fly around in gps mode if you mount it directly on the powerdistribution. Just in case you use harakiri set gps_rtl_flyaway = 15, so the flyaway will stop after flying 15m in the wrong direction on rtl..... After the...

@Truglodite: I haven't tried "Racer 5", let's see where to find that canadian beer here... Really don't know why the stick commands don't work with your setup, maybe it's something with your overclocking. I don't have that barebone knowledge, I have to trust in the supplied libraries/drive...

Sorry if you was getting my post wrong, alberoLG. I didn't want to offend you in any way - it was meant the opposite way! Having another hardware supported (letting the price alone) is always some good idea and has to be encouraged. If you want to get the full benefit of the DJI GPS unit you will co...

Crashpilot1000

After engaging RTH in full flight, it will brake and do a PH & Althold (and gain some hight, if specified), if some requirements are fulfilled the RTH is engaged. So when your mag isn't working properly that stuff goes wrong in the first place. An RTH without MAG is possible on copters (easier o...

Crashpilot1000

Well, when RTL is activated the other needed boxes are turned on automatically. It sounds like magnetometer problems with your setup. When it flies in the wrong direction, (nearly) no matter what your pids are its a mag/declination problem. The bearing calculation is much more precise than in mwii (...

Crashpilot1000

albertoLG: "seems everybody hates what I posted..." No! If you have such a unit lying around (with a crashed naza) it's not a bad idea but the undisclosed/partly hacked protocol is the problem. Going for that overpriced hardware in the first place for and opensoftware platform is like buyi...

The dji gps combo is maximal unattractive for an open source project since the protocol is partly reverse hacked and will produce unwanted surprises.
There are gps/mag combos already available:

Did you ever come across the idea to arm the fc like described in mwii wiki? If that doesn't work, sell the board or buy a radio that reaches the appropiate stick limits if you are not able to change them in cli or your TX. Arming hasn't changed for "several months" in any mwii "unive...

I also noticed various file lengths through gcc versions. They are all a some precious KB longer than the keil compiled hex from tc (using the same code for testing).

Short notice, a first test Version for v5 is in the github repo. @Hinkel: Well an osd switch why not. I have to find the code behind that. @aBUGSworstnightmare: I am using the free version of Keil + gcc. So you want to do another I2C oled driver. Well, perhaps it's better to do that on TC code, beca...

I think with kvosd you can solder up an ampere sensor. I am currently not working on that.

Hi, satnaam! Yep my private little project keeps on rolling . The 2.6 final is not ready because I want to reorganize some of the GPS stuff and squeeze that "I returned to home but do sometimes not autoland" bug and needs more testing. The current repo has bin and hex files in the main dir...

That OSD stuff is probably baudrate associated (115K vs 57K). Since KVOSD is a very nice project stick to that. Having native minimosd support isn't a bad idea because I am building a fpv backpack with minimosd. So I can attach it to my (new!)radian pro with arduplane and to my naze copter. Over the...

Well I did some flashing in the past with passgps (not in conjunction with a gui only terminal and ucenter) and I can assure you that it works well, if used correctly. Even MTK works. gps_type = 1 will send the mwii ublox configblock (override settings to 5Hz etc) and put the ublox into pedestrian m...

Crashpilot1000

Well basically I2C GPS is not such a bad idea on Arduino because you can offload the main FC with the GPS cycles and even do more complex calculations that are not possible on a single Arduino handling FC and gps (like a precise bearing/heading calculation). The bytesize can be greatly reduced (IF t...

Hi! Well, the gps .... oh, boy. First of all there are a lot of changes in that area and the functionality is not truncated in Harakiri.

@Hinkel @Truglodite: Thanks for the condolences, unfortunately the lightning struck twice in one week... But I am back on track! @Hinkel: I am glad to hear that this was mainly due to a setting done by your tx, so the althold gathers up the needed throttle fast enough. Anyhow I rearranged the FS stu...

Crashpilot1000

Hi, Hinkel! Sorry for the misunderstanding! If your copter is equipped with a baro (no matter if activated or not) the failsafe_throttle is ignored. It worked with older versions because they had no "debounce function" for landing. The debouncer will limit the maximal thrust during landing...

Hi, Hinkel! Thanks for the report and having the guts to test that out! I think there can be done something about that.

You can start directly but expect a slow decrease in althold hight when enabling during heatuptime (depending on hardware/foam etc). Just be aware to compensate for that (if needed in low alt) in the first minutes - not nice but not such a big deal after all. P.s.: That will not win you a price in a...

Crashpilot1000

@AlexIP: BaroAlt = (1.0f - pow(pressure/101325.0f, 0.190295f)) * 4433000.0f; That actually IS temperature compensated, because the baro does its own temperature compensation based on it's calibration data. But it can not overcome a problematic hardwaredesign. The Arducopter approach in the IMU will ...

Crashpilot1000

@Sebbi: Yes, definitely. I thought the heating/hight influence would be diminished but after further tests, I see the same results like before. Perhaps some temperature factor on the ground could be gathered during heatup for further compensation (the "curves" look rather linear in the int...

Crashpilot1000

Hi! @pm1: Thank you very much for wrapping your head around that subject. From my observation the baro heating up seems to be greatly dependent on the hardware implementation and foam coverage.
