+1 for 32bit

frog32

@Crashpilot1000: You should take a look at this documentation http://git-scm.com/documentation. git seems hard but it can be a blessing when it comes to tracking changes, finding bugs which weren't there some versions ago and letting others contribute. if you have any problems or questions you could always ask.

frog32

To remove the stm32 just cut every leg with a precision cutter. After that it's easy to remove the legs from the pcb using a soldering iron. I know it kills the chip but we are talking about replacing a broken chip.

frog32

Why only this sub forum ? I don't think we will suffix every subforum by _8 or _32 " Board index ‹ 32bit section ‹ General discussions " should be explicit enough Not every subforum but people come to the forum the first time and see "General discussions", before they realize th...

frog32

Back in 1996 when i picket this nick 32bit was decent. But i 've started microcontroller programming on an 8051 which was only 8bit, so my nick doesn't come from processors but from my shirt number back then.

frog32

I want early beta access. If i remember correctly you want to implement the osd on the ground using the telemetry data. Will there be some analog inputs and some io's left on the board to be able to switch between multiple receivers? Would be great to include diversity logic into the same chip.

frog32

Multiwii config file recommends 1300 https://github.com/multiwii/multiwii-fi ... nfig.h#L59 but i had also good results using lower values. I don't know the best values for 30A plush.

frog32

When it's gonna be released?

frog32

At least half of the topics started here belong to the 8 bit section. I propose to rename this subforum to "General 32bit discussions"

frog32

are you sure that you 've posted in the right forum? i don't count more than 8 bit's on your flight controller and this is the 32 bit section. try to repost it in under general topics

frog32

do you use turnigy plush and didn't set minimum motor output to 1300? under 1300 the motors spin to slow and react much slower resulting in overshooting and reducing the other side of your motors to less than 1300...

frog32

i tested this new build, if i try set gps_baudrate=-1 (autodetect) the cli crashes. i am not getting any response from the naze32. if i try the correct baudrate it works just fine as timecop said

frog32

But it didn't in my case. It could only use it as a ubx gps when i did set gps_baudrate=4 (9600 baud), but i didn't realize that it should have worked then

frog32

Then you might want to recalibrate your esc's

frog32

Ok this is working for me. But what are the optimal settings for baseflight?

- 115200 baud
- protocol in and protocol out only ubx
- which messages are needed? i like to kick out everything else

or at what baudrate do i have to configure it so autoconfigure will work in baseflight?

frog32

then my gps must have been shipped with off settings. how do i reset my gps?

frog32

Hm, unplug minimOSD? this is my setup, only bec for power, gps and usb IMG_0876 copy.jpg now i tried almost every thing. gps_type=1 and gps_baudrate=4 seems to work using the latest available in the downloader. i have absolutely no clue whether it is successfully initialized and working using at le...

frog32

using this code and building it using yagarto i get a working hex. but then i get gibberish like this in the cli after i activate gps and set gps_type=1 $M<ee$M<ll$M<kk$M<nn$M<ee$M<ll$M<kk$M<nn$M<ee$M< and if i set gps_type=0 i have an imediate fix and 7 satelites. # status System Uptime: 429 second...

frog32

That's why i've connected tx and rx (the last one on the top and the first one on the bottom row of pins). tx and rx are not reversed, this would not have allowed the nema setting to work. i'll reset the whole controller once again and download the newest hex using baseflight configurator, but i don...

frog32

Mine is a stock crius neo 6m. Never hooked it up to anything than baseflight. I first tried with default settings in baseflight and it worked. Then i've set it to gps_type=1 and since it doesn't work anymore. If i set it back to gps_type=0 then it is working again. Is it possible, that this gps it o...

frog32

The same thing here, just flashed the newest baseflight using the download option in baseflight configurator. The gps works fine using gps_type=0 and gps_baudrate=0. But it doesn't work using gps_type=1 and gps_baudrate=0.

The GPS is a ublox NEO 6m from crius.

frog32

No mavdink. And probably won't happen unless there's a damn good reason. All the mavlink ground stations are fucking horrible looking. I only want to have mavlink because it's well documented and open. But if you show me a good documentation for frsky i'll write my antenna tracker to talk frsky. Bu...

frog32

Does baseflight support mavlink? i am not talking about being able to alter every parameter using mavlink like this crazy thing m i am only interested in getting flight data out of the controller during flight currently i am looking through the diff between harakiri and baseflight, i will post my re...

frog32

I have two questions about harakiri: - is there a repo available to be able to track the changes? preferably git but i am also happy with everything which is able to show the actual progress. - what are the differences between harakiri and baseflight? i would be happy to look this uf in a repo mysel...

frog32

The failsafe controller uses only hardware that is readily available on a standard quadrocopter, and could thus be implemented as an algorithmic-only upgrade to existing systems. So it should be doable, but they have arm processors as far as i know on their quads. I once attended a talk about them ...

frog32

@timecop, @Truglodite: this code is about one year old and i have not added all the settings needed to cli. if you look up this commit and ignore all the #ifdef FFOSD and updateOSD() stuff it should work

https://github.com/frog32/baseflight/co ... b1119f5c84

frog32

that guy who used the adc with a current sensor was me. i hat reasonable results using it as a powermeter but i don't know if it is capable of alarming you because i use it with a max 7456 to display used power

frog32

@PatrikE: it is very difficult to see the actual code changes, what's de version of multiwii you started with? i like to diff it and try to review the actual code instead of just putting it on a plane and try to guess what it supposed to be doing.

frog32

o ordered a second gps because i don't want to test this with my knurrus maximus fpv. did you try putting a logger on the plane to verify if gps data is sane? maybe you got some interference during flight. you use a compass to navigate. maybe the main power line is next to the compass which could le...

frog32

what happened to your rth implementation for airplanes? i thought you had a flying prototype.

frog32

There was an error in the adcChannel skipping mechnism. with this patch it should work:
https://github.com/frog32/baseflight/co ... 4c8edaa3e5

and here are my changes to add powermeter support:
https://github.com/frog32/baseflight/co ... b1119f5c84

they aren't done yet and i need some more configurable variables to let users trim their current sensor. i'll do some testing later this week

frog32

does this mean you can't order them to japan?

frog32

What about bringing powermeter back? I have an ACS756 current sensor on my plane and it would be great to be able to use it in my osd which i integrated into baseflight. I tried to mess around with the adc and the dma but i didn't manage to measure anything with it and even killed vbat measurement w...

frog32

i 've tested it today and it seems to work. i wasn't able to test fly it but the corrections are being made in the right direction, and motor is working again.

tanks

frog32

not it's not on and it's realy wing output i have gyro correction, and also the radio input in it and it reacts to changes in pitch_direction_r etc.

frog32

on pwm1/2 i have valid servo outputs but they seem to be the wing servo mixes. maybe the servo mapping is wrong and it overrides motor out.

Your pwm init procedure is too crazy for me without some more comments. But the Problem seems to be in there.

frog32

@timecop: tried flying wing again. mixer seems ok. i couldn't start the motor and tried to reduce motorpwm to 50hz. i even tried probing with a servo. which pin should be motor out on flying wing? is it possible that pwm initialisation doesn't work with flying wing?

frog32

thanks for bringing flying wing back. i'll test it as soon as i can leave the city. regarding your mixer thing: what about having a set of configurable mixes like in er9x (m). it would be enough to have those sources: rcchannels, pid loops, fixed value and a weight for each of them. it's not that ea...

frog32

I have a solution that looks like a turd, I can commit it today. Or I can spend some time on it and make it nice - something most 8bit devs dont seem to care about. but it would be good for all who are also coding on the same project. i am waiting for your solution i nearly went back to the last co...

frog32

thanks i'll try this tomorrow evening but it looks simple

frog32

i am currently implementing an osd feature based on the max7456 for baseflight. some early bits of code can be found here https://github.com/frog32/baseflight/commit/e332f740b990a6227006e6be2bdd531a23cc4b88 to read out a current sensor i need to have two more analog inputs. i didn't find documentati...

frog32

@patrik: how is the fixedwing navigation going? had you time to tweak it since you first postet the news about it?

greetings marc

frog32

i think the best way is to use the githubrepo m and fork from there. once there are some developers using git it's easier for alex and other developers to decide if they want to switch from svn to git. i saw some big projects switching from svn to git after more than 50% of the contributors used the...

frog32

+1 I use git every day and it makes it so easy to do local changes without loosing track to upstream updates. it actually encourages me to contribute to a lot of projects. svn makes it really hard to tack code, if alex is merging shared to his branch it's almost impossible to see who did this stuff ...

frog32

Yes airplane mode is included but not fixed wing navigation.

frog32

Any chance getting the fixed wing navigation so use separate variables in gui not using some unused ones? I don't have a flying plane right now so i can't help testing until my flying wing is completed.

frog32

as far as i knew, the speed should be calculated with the doppler shift. because a gps already has to compensate the doppler to be able receive any signals. without compensating the doppler you only receive the satellites which are near the zenith because then the movement of the satellite would be ...

frog32

On which version did you build your code? i tried to diff your code and MultiWii_dev_20120504. I found quite a lot of changes.

frog32

Sounds great for a safety return to home on a fpv plane. What's the needed setup? gyro, accelerometer, gps? or do we need something else?
My flying wing isn't finished and then i need to port this to stm32 because it's what will drive my plane.

Marc

frog32

Does it navigate rudder only? Or do you bank the plane? I'm just thinking about flying wings.
