I came across this when reading a Chinese MR forum... the person claims mwc was setup to control over wifi with ios.... he did not give any further information.. I doubt it might be fake.. but just feel like to ask here to confirm. judging from the pic.... the ios control app is similar to ar.drone ...

reduced to $100 shipped to cont us.. they must go

jy0933

this is what i found from ublox spec

seems 6M only got 1hz?!

jy0933

you gotta use mega2560board... for this.. but it seems the latest dev common-lized all the ports.. so all serial can be connected(pnp) for any serial devices..

jy0933

i was reading the changes in the dev code.. since ublox6 all support 10hz refresh rate.. why dont init-config to 10hz ...but rather 5hz?

and also the gps speed filter that eliminate random glitch(sunnden pos to 100m away and back to right pos)?

[s]just wondering if sonar is to be added to next ver or not?

[/s]

found in change log it is in
I felt all my MRs fly much better with mwc over APM.. sonar will really be helpful for close ground acro (~1.5m)

and GJ

jy0933

it would be up for sale for a while .. until they are all gone... gotta sell them to fund for the other parts

jy0933

what im saying is even with such level pid... in auto-level mode the return to level is slow and not significant

jy0933

i have tried to move P up to 13 and I 0.5....

the return to center is still slow.....

here's the current setting

i'm totally lost what to do now

jy0933

thx.. i'll give it a try when i got back

isnt according to mwc wiki.. we want to keep roll/pitch P + Level P is about the same value as default?

jy0933

jy0933

i found the recovery speed from angle is slow...

say i pitch forward... after release stick... the quad does not return level immediately... but staying forward...

what PID should i look into for this case?

thx

cant open the website to look at the product.. it is just me or?

I found the problem with altitude mode is that if i hit throttle by mistake.(which happens a lot when yaw)...i might end up losing altitude after tuning baro off. because wrong throttle pos here's the concept to prevent this problem. could be a great add on for FPV/APers.. anyone is welcome to take ...

jy0933

may I give some suggestions? afaik... it is possible to output frsky telemetry sensor data to pc thru ftdi. for FPVers, (i dont know how many people like me using laptop as display) it will be pretty useful if i can get all info from one screen. I feel the realtime data page can be modded to be a gr...

jy0933

Is it possible? Yes. Tommie has some custom firmware that's been used by Pyrofer to drive a regular RC transmitter with a PS2 controller (Tommie's also used it to get a lot of features out of a very cheap radio). It would be possible to modify that setup to use the xbee instead, and likewise modify...

jy0933

it happens randomly.... the last time i have such problem was that there is the serial rate difference between xbee and FC setting.. might help.

jy0933

can i get some help about i2c_nav board +cn06+328 board here's the steps i have gone thru 1. solder 13&14 pin to enable 38400 >> connect cn06 to ftdi tested with u-center. got gps fix and able to locate 2. download fw "I2c gps nav v2.1 rc2 (Wire lib issue fixed)" 1)add following code u...

jy0933

awesome.. then it should solve the entire problem now

jy0933

i actually have changed the radio to frsky.. but the jumping has nothing to do with the radio.. just the sticks

jy0933

@alex.. i actually figure it out on tx side.. but i can use some help on mwc side..since some of the parameter i still cant figure out well i attached tx setting for my case below.. but on mwc... when tx is on max throttle stick.. it shows correctly that the input is 1500 roughly.. but in gui, if i ...

jy0933

you can see the video i uploaded... aux4 has input.. and it is t9x mod er9x 8 channel rx

jy0933

i was testing some switches indoor

mwc mega2560/ ublox gps 115.2k 5hz

i was putting on gps hold and gps home for aux4... and i found the option does not change to green when switch is on.. is that because the gps do not have signal? or i did something wrong on the settings?

thanks

jy0933

does it has to do with the ESC?

i got my esc flashed simonk fw.. should i change here to enable the high update rate for better stability?

or where should change to get to 400hz + for better stability with simonk fw esc?

thanks

jy0933

and one more thing for wishlist.. im not sure if other people has similar problem but i think it is worth to add background.. my er9x the stick reading around center jumps around from 1495~1505.. so i set deadband 20 so that 1490~1510 are consider 1500 then i found when i tune the quad, i still need...

jy0933

i dont know if this should be a tx problem or fc problem or both.. so i kind of cross-posted @ mwc/rcg and here.... hoping there might be someone can help out... thanks background info: im trying the high S low KV method for my quad thread link if you are interested http://www.rcgroups.com/forums/s...

jy0933

just btw.... probably give a fix on this fail too

data/gps logging problem

.txt file does not record anything
(.kml does have gps alt/lat/longt reading)

just a quick sugg.. can you add time along with gps logging..

jy0933

i just came up with this thought.. is it possible to replace the radio with xbee set if xbee can be use to replace radio.. then it might be able to enable we to use computer to monitor the ambient(telemetry) condition and control the vehicle pc joystick(flight joystick.. heck yeah!) .. and it is dig...

jy0933

you can get voltage from any vcc/gnd pin... and i dont know for sure.. but you can probably try to parallel bt on serial 0...

but yea.. it is still useful to be able choose bt port (esp on some boards that the ports are preassigned to xbee/gps while i dont even use those.. and simply want bt)

jy0933

i dont quite understand what should i look for at cycle time?

connected sensors: gyro/acc/baro/mag
enabled function: auto level all time

just a btw.. when connected thru bt, both mwc and wingui have significant lag. baud rate has set to 115.2k for best performance

jy0933

I have no idea what should i call the problem.. but here it is I was tuning my quad thru bluetooth connection.. and i notice sometimes when the connection is established.. or after write the config.. the quad goes into a "chaotic" state.. such as, only one side of motors spins up when you ...

jy0933

baro/alt hold is not on
i'll try gyro only mode and see how it goes.. but it might have to do with pid.. and maybe esc.. i'm waiting for several hk10A to flash with simonk's fw to have better performance.. the current ones are hwss20A....

thanks

jy0933

even tho the faisafe is enabled... there is still throttle output that spins the quad....
( you dont want the failsafe cut off all the throttle while in the sky dont ya

jy0933

this is the situation i encountered today... while testing and tuning... radio went out of battery (4x4 AA are dead) it was close ground testing.. so basically 20cm away from ground.. not too bad... i managed to catch the quad and hold in hand... i tried to turn on the radio again for some hope to s...

jy0933

the problem i have now is ...

on default pid... it does not behave wooby.... no pitch/yaw/roll oscillation

but the hovering oscillation- up and down. (acc+gyro+auto level on),,

i think i need to get away up and down oscillation

any good idea?

jy0933

altho i have read thru the entire thread for several times.. i'm still confused is there a code to insert into mwc to config gps chip to nmea, 5hz, 57600baud when power is plugged in? the gps i have is serial ublox-neo-6m, at default 1hz, 9600..... fc is mega2560.... fc is working with the gps alrea...

jy0933

just a quicky according to wiki... For stable flying (RC) Increase value for P until oscillations start, then back of slightly Change value for I until recovery from deviations is unacceptable, then increase slightly Decrease value for D until recovery from dramatic control changes becomes too slow....

jy0933

multiply you budget by 10 .

or mod a tx to be able to take input from computer...
then write/find a sw for outputting the ppm signal from audio out.. simulate the joysticks on your pc

cost.. a lot of time..

jy0933

just out of curious

when it is 45deg from original orientation... it will act like + config.... or even doing the forward as forward at any deg turn?

jy0933

cool.. thanks

this make sense to me now

jy0933

so basically headfree is to disable yaw stick

and mag is whereever yaw makes the quad point to.... it stays until another yaw comes in

right?

jy0933

I wonder what is the difference.
once defined in .ino, mag is on all the time.

head free is straightforward that it is just direction hold..... but what is the mag for?

thx
