I think there are a couple of bugs with the latest baseflight build from github repo. The first is with the servo config tab. The servo info via the CLI 'servo' command is correct, but it appears corrupted when accessed via the servo window in ezgui. The values are all scrambled & incorrect for ...

This is ridiculous and very stupid. you admit that it's illegal, and yet you don't even bother to setup RTH and failsafe features, you just allow y...

@Leo, is your computer cpu hitting 100%? If so, then maybe that's your problem. I think someone else mentioned that the java app will completely load the processor, and on a slow computer, it will freeze and not respond. I've had it happen to me as well. You need a relatively fast computer with a lo...

@Rubadud Vario rate – yep its on the roadmap. Quite likely for next release. Pitch / Roll angles – is quite easy and I think not much memory. Probably in conjunction with schnupperm’s comments above. Disabled by default. Most likely not for next release. I require this as well. are you accepting PR...

In gps.cpp, function GPS_bearing() *bearing = 9000 + atan2(-off_y, off_x) * 5729.57795f; could be simpler, faster and shorter *bearing = atan2(off_x,off_y) * 5729.57795f; Also the parameters int32_t* lat1, int32_t* lon1, int32_t* lat2, int32_t* lon2, of the function do not need to be pointers.

Is this code base stable enough to use as a daily flyer? if I am not using the nav point, I like the idea of the fence/RTH code. I'm currently using it for daily flying. I don't use the NAV features other than RTH, pos hold, and LAND. It seems to work fine; there's not much difference from the regu...

Spin speed is governed with your MAG P. value simply lower MAG P to slow down spin speed. ok, thanks for the tip, but I've already starting to make some other changes to the NAV code. I've implemented the rotation limit that I mentioned above, and am also adding some logic to enable a couple of oth...

thank you

where is the source code repo for ez-gui located?

csurf

does running comp_pwm increase the risk of damaging or burning up ESCs?

are there instructions on how to compile ez-gui?

need some advice/feedback on the following. I'm running EOSBandi's latest 2.3 nav version. During testing of the NAV functions (RTH, NAV missions, etc), I've found that the changes in heading are very abrupt. Within the GPS code, I saw the following... //GPS.cpp @ line 828 void GPS_adjust_heading() ...

This change in board temperature can cause a big error in the calculated altitude readings. Why should a digital microcontroller show a big error when temperature changes? The only parts being affected by a temperature change are the analogue sensors. MultiWii code has already the temperature readi...

csurf

@csruf MultiWii code has already the temperature reading of the baro sensor for properly adjust the altitude reading. yes, that's correct, but I was referring to the gradual temperature rise during the time that the board slowly heats up to operating temp after being powered on from a cold start. T...

Why is it be impossible to do a temporary PosHold after a GPS failure? Just use the vertical acceleration values instead and try to keep them "zero". Or am I too naive? Not sure if you mean 'alt hold' via the vertical accel readings or an actual position hold (which I think might be tough...

csurf

i agree, it should be calculated correctly in all cases if possible, even if that means seperate formulae following the existing MWC pattern of adding new conditions via pre-compiler defines, something like the following could work... //config.h #define POWERMETER_BIDIR //Multiwii.cpp #ifdef POWERM...

Not sure about the code as not had time to look so this might be bollox... but consider some use bi-directional sensors... e.g. O current showing around 1.5v Increase in current may be recoreded as a decrease in the analogueread() value from the 0 value depending which may its connected...

another quick question about RTH... I'm looking at the code and trying to understand what happens during a GPS NAV event, such as RTH, if the GPS fix is temporarily lost (possibly due to issues with the serial link and/or if the sat count drops below 5). For example, it *appears* that an RTH action...

thanks haydent... I think its either just broken or whoever wrote that piece of code has a weird current sensor. I've been testing with my version and it seems to actually work now... Not sure if the mwc code maintainers will want to take a look at that or not. Hopefully this can at least serve as a...

The "reason" the code does ++ in each switch() is because when there's no mag for example, it will just get incremented and fallthrough to the next (where it also might just get incremented etc). If there's no mag or baro or whatever, your version of taskorder will only increment by 1-2 p...

question/comment: the multiwii wiki article on altitude/BARO tuning recommends adjusting the altitude D term in 0.2 increments... m Set P and I to 0.

I need to adjust the powermeter variables PSENSORNULL and PINT2ma *without* having to wipe out EEPROM (I have my settings configured and so I don't want to touch them anymore).

It appears to me that you have not understood the coding completely. That is no a shame. But, lowering the performance of the developers by using words like BAD, HELL, HURT, etc sounds very arrogant...

With my project, I had the idea that I'd eventually start stripping out a bunch of extra stuff that wouldn't be needed for RTH...It would only support either Rx pass-thru or RTH and nothing more...

I believe in keeping things simple or as simple as possible. The key to all of these parameters is not just understanding what they do but also what their limitations are. It is impossible to cater for every eventuality. I'm sure that if asked to define a list of all the scenarios where RTH could/w...

so going back to the topic of RTH and initial height, the default is 0cm! So you'd be very unlucky if you needed to initiate this and you were below the treeline! What about failsafe initiating RTH?

update for anyone interested... I successfully managed to get passthru CPPM output to work.

What flight characteristics do you like about the KK2?
