Hi, Hinkel! Actually users will die one death when switching modes with zero throttle. I once had programmed a solution (for mwii version) with softexit. You quit Baromode by flipping the switch but the copter would stay in baromode until you reach (or surpass) the actual motor - throttle with the t...

Harakiri does not and will not have support for pseudo 3D ESC stuff. Mag is not needed for flying upside down.

Thanks PatrikE and fryefryefrye for the info! Sorry for that question but my last plane experience was 25years ago with a cessna (methanol/nitromethane/oil fuel) and crap 27Mhz RC .. - RIP.

Hi! Sorry for OT post but I have a question concerning planes. Mine is still sitting on the shelf.. Planes require lift and have a stall speed. Gliders don't need to have the motor running all the time. GPS will not report back the actual airspeed under the wings. So how is an automatic mode suppose...

Thx for the info!
BTW I found an old schematic in the fpv community forum. I wonder where the actual layout plan is.
Attached here anyway....

Hi Subaru. Those witespyquad boards are Nz4 compatible as far as I know. Currently working on a version . I bought a flyduino mw32 (version 2) too early to say something definitive (until sitting on a copter and flown) but witespyboard looks better designed than that (seen on the picture of your lin...

Crashpilot1000

Seems you stumbled over something not thought through in the code. In that case you will have to short the bootloaderpins and reflash the FW. I never got that working with the paperclip method, so I soldered 2 cables to it wich I can short if needed. That will work. 100% .

Crashpilot1000

Yes, Failsave needs some attention I did *some* work in that area. One way to cope with simple RC stuff is a deadpilotdetection (not moved sticks for some time - within a margin). I had the idea doing that for copters while seeing a reportage on Trains on TV. The funny thing is, that DJI came up wit...

Crashpilot1000

Well, yes summing up accelerometer values without doing complementary filtering with a different datasource (gps/optical devices) is very problematic. It may not be impossible to make that *somehow* usable for maybe a little support against a sudden strong wind. You can detect the change in accelero...

I already "PMed" you some codelinks that will most probably do what you have in mind - though I don't know exactly what you have in mind... lol.

Dunno where the problem is. Maybe someone should cast a vote if there is demand for sonarsupport, and what the user expects it to do exactly.

Well the antenna doesn't have to be well tuned for the frequency band (for the detect-flyby-RX) since the crucial info is in close range to the sender.
I agree the idea is off topic concerning ucscSeniorDesign project - and was just an idea how a non gps rth could be done. Sorry for bothering you.

Crashpilot1000

I wont be so sure of that with your moiree reflections. Due to the magnetometer the copter knows the direction of home and could turn nose in and fly back with a predefined tiltangle (speed feedback not available, probably impossible to gather with rssi - reflections etc). The nose could contain a d...

Crashpilot1000

@ucscSeniorDesign: Looking forward to it - hopefully there will be also a non scientific version for normal people like me... @copterrichie: I was thinking all the time - at least a RTH should be possible without GPS but that would require more receivers with RSSI output and and some directional ant...

Crashpilot1000

Hi! You can put your desired angles here: m replacing GPS_angle. The copter has to be in angle (preferred) or horizon mode. The Angles in mwii are expected to be in DEG and multiplied by 10 so 30 degree = 300. If you want to use the "slew rate" (m) of GPS the angles are expected to be mult...

Don't want to spam another thread. Concerning the Auxchannel readout this might be also a way: uint16_t auxState = 0; int8_t auxShift = -1; for(i = 0; i < 4; i++) { auxState |= (rcData[AUX1+i] < 1300) << ++auxShift; auxState |= (1300 < rcData[AUX1+i] && rcData[AUX1+i] < 1700) << ++auxShift; ...

Neptune: You can pick one up in the meadow! @mj666: Not sure. 2.5 is save if the normal controller is used (like default). BTW: Maybe I2C sonars could live in the sensors autodetection but skipped with feature pass enabled. Anyway, I will have to add the disconnect detection for I2C sonars. Otherwis...

@Hinkel. Thanks for checking that! I had a chance to check that today between the rain and yaw is a little slow, so I changed the default YAW speed line to: (2 * "(int32_t)cfg.yawRate + 42" (was +30 before). +60 is very nice on my copter but I will leave it at a lower default rate so it ca...

Crashpilot1000

Yes, but without gravity acro only. The PID controller would prbably need a rescale, gyros should work since there is some mass moved on the chip.

Hi, Mike! I am currently using the "if (temp < -1500)" version because it seems to me that it gives the most accurate results and hopefully does better at > -15deg. I guess that is what you refer as code 2? Thank you very much for checking that out! The next step could be a hybrid of all 3...

Crashpilot1000

I think the -15 deg temp compensation is missing in current mwii code. I add here code for two alternative MS baro calculations that work. I changed it back to bitshift for dT calculation. I checked for out of bounds with the datasheet example values. Maybe that is helpful for you. #ifdef Alternativ...

Crashpilot1000

NP actron! Thanks for wrapping your head also around that issue. I haven't noticed it since I put the ms driver to floats (mostly) but the dt calculation can be done as accurate with bitshifts, so I will change that partly back as well for the dT part

Crashpilot1000

Did you ever bother looking in the trunk?

Crashpilot1000

Simply because it didn't work as well as hoped. I never really got the default pids tuned right and timecop didn't like the float pid factors, because they don't blend in nicely with the 8-bit defaults. If you like playing around with beta stuff, give it a shot and we might find some values that wo...

Crashpilot1000

That would be angle mode.

Crashpilot1000

@QuadsDestroyer: Well, you could enable the alternative PID controller (uses delta T) and set the looptime to 1ms (1000) - I think it's setable in baseflight. In that case you can be sure that even a 500Hz ESC has always fresh data. If it's an improvement? - You will have to ask/trust in the guys wi...

Basically the absolute hight upon engaging althold is irrelevant, so setting it to zero (with an offset) on the ground is just necessary if you want to do an RTL with a predefined hight. The baroreadings are affected (next to unclean powersupply, missing cover and sunlight) by TEMPERATURE. So the he...

Crashpilot1000

@aadamson: Agreed. Probably mixed up some axes, I orientated myself with the NED nomenclature. I keep the code in the repo, just in case it might be a starting point for others. I thought I solved the problem but freeflight test showed me not a good result. I will check back to MARG sometime (and tr...

Thank you & SergDoc very much for kicking that off!

Would stick to 2.5 for now, still figuring out stuff. You can also use that viewtopic.php?f=23&t=3524&start=520#p45985 it's also test flown.
Still can't get marg working better but the accConfidence stuff seems to be good for althold in motion.

@aadamson: Thanks again for your input! I want to keep you posted on my MARG progress. The main problem I have is that I can not get the parameters tuned in well to rival the over all result of the existing core. I just upped my actual marg status and will leave it at that stage.

Yes, BMP085 has a lot of noise and produces the observed +-0,5m accuracy. On top of that it also has a noticeable awful lag.. so the necessary filtering will make it worse.
