sure, kv/mw osd do this currently (have a look at their code), so its totally possible. though the pwm signal will be different between rc channel and rssi channel and likely different between receivers.

Another option is a low pass filter (cap and resistor)

the line number is calculated wrong starting at 0 when it should start at 1-4, causing missing line at end not sure if my fix is best way to do it, but works in my case. i just took formula from other pages for doing similar thing and it worked... also i made it show if armed by stick LCD.cpp curren...

haydent

You cannot. Configure a hex and use your private mixing with avoiding the motor[x] which relates to broken pin. If you cannot figure that out buy new board this works easy enough concept is, enable copter type that has more motors, then specify layout file so extra available motors have same values...

haydent

i think youll find x8r is not supported by this code, some day it likely will

haydent

maybe post a screen shot of your gui aux config

haydent

yes, this mod will not work with any servo code, stock works for me

Ill try that today, report back later, but would that really make pos hold basically not work at all?

well if your mag is not correct the copter is likely to go in the wrong direction

haydent

sure that is possibility that i thought of too, and i guess it is a matter of how much time someone wants to put into it vs the need. good to have as comprehensive system as possible. but what if your lipo plug disconnect ? or a esc wire... there are many points of failure

haydent

in a way this already exists with modern tx controllers and this likely why the existing code has not been developed much further. as you can set your rx failsafe so it reverts back to pre chosen state on signal loss. eg you can make an aux channel default to RTH on signal loss. you will find other ...

haydent

nice job on the tx, what is the advantage of this over a lrs link?

haydent

servo only, they cannot control brushless motor. generally a gimbal will have the option to come with a controller

haydent

its likely you can still use your rx normal output pins as well, but otherwise here is how to pass through a rx channel: viewtopic.php?f=18&t=5417#p54208

haydent

i have done this, it is here: viewtopic.php?f=18&t=5417#p54208

haydent

unfortunately those links dont work, and also you will be pushing up hill to get this sort of support here, this forum tends to lean on the technical side of things, at the detriment to beginners... i will agree with your thought to get a mega 2560 based board rather than anything less. as you will ...

haydent

#1 yes you can use any serial port, your will need a serial inverter cable like this though, available from various sources including: m #2 i dont think it is that simple though your more than welcome to try. really though it doesnt matter what order it is really ? if you are using sbus it is all st...

haydent

is your mag working correctly ? maybe it needs callibrating

haydent

i could not compile without making the boards.txt bit like this instead:

Code: Select all

lilypado.build.core=arduino:arduino
lilypado.build.variant=arduino:standard

haydent

just a wild guess, are you using the right motor outputs ? maybe have a look at the config servo settings

haydent

I got it working fine. It might help for you to work through your system bit by bit. So start with a multimeter on your signal wires and check you are getting a voltage that fluctuates as it should in correlation to voltage and amperage. Then check the fc is reading the values by using debug[0] = va...

haydent

many problems here 1) you said no problem with spektrum, but the code for spektrum changes also 2) Plüschi suggested of mod http://www.multiwii.com/forum/viewtopic.php?f=8&t=4425&start=30#p45299, and in this mod (r1648) readSpektrum() was removed form readRawRC() 3) were all side effects ta...

Does anybody know if its possible to feed Sbus in to the MWC but then output any extra channels for things like gimbal pitch/roll, camera switcher, lights, things like that not related to or reliant on MWC? I have a Corona 7ch Sbus compatible Rx, but when using Sbus I can squeeze all 10 channels ou...

haydent

ok here is a quick mod that enables 3 rx channels (in this case 9, 10 & 11) to be output on pwm outputs camroll, campitch & camtrig. as such it is incompatible with using SERVO_MIX_TILT, SERVO_TILT or CAMTRIG config.h options (though the output pins could be changed to unused motor outputs i...

haydent

the number of users that have asked this i have noted, and it would be simple to do. i could make it. but someone else i was talking to about it, said that on the x8r rx and maybe yours too, while the sbus was being used you could still use the standard pwm outputs for other things, like the switche...

haydent

The failure can be seen in the GUI. Something is happening to the decode of the sbus channels. Channel 1 is moving to channel 3, channel 2 is moving to channel 4 etc. The good news is this was found with ground testing. This would have been a disaster in the air. John i had no problem, i copied my ...

debug[0] = rcValue[12]; debug[1] = rcValue[13]; debug[2] = rcValue[14]; debug[3] = rcValue[15]; just wondering if there was a native way already i had not noticed. thanks. i made a modified version of the gui that shows all 16 channels: m http://www.multiwii.com/forum/download/file.php?mode=view&am...

haydent

Hi, I've just committed the mod suggested by JohnB. With no option (permanent mod) I think current SBUS users will have to look carefully at the change mod in next version. From what I understand, I see no reason to make post scale treatment on spektrum system. The fact users have to increase the t...

haydent

so how do i test 16 channels in MW when the gui only shows 8 ? or did you have some other method in mind ?

haydent

Tested out your sbus code again John and seems fine still. I have corrected an unrelated sbus + lcd conf bug. Do you have the ability to test sbus with 15 or 16 channels? There is some sort of problem doing that with the current firmware, see my previous post. I tried it with the original 2.3 relea...

haydent

yes i have taranis/x8r and rigol dso if needed. ill have a go, never tried > 8

haydent

Tested out your sbus code again John and seems fine still. I have corrected an unrelated sbus + lcd conf bug. Configuration via lcd has its own loop while viewing separate to everything else. Problem is it was not reading sbus data as part of that, only spektrum and standard. Therefore once inside t...

haydent

thanks John, your thoroughness is great !

haydent

i can see the need for both, but personally only need sbus as well. how about 2 seperate patches with seperate config options in their respective rx sections ?

haydent

this is great you can understand each other, when we get it worked out, i have another member with commit access who can add it to mw shared.

haydent

sounds like a good opportunity for you to learn arduino

haydent

you can just disable the onboard one in mw code if thats what you meant.

this guy might sell you a compass module seperately: http://www.multiwiicopter.com/products/ ... -autopilot

otherwise ebay: http://www.ebay.com.au/sch/i.html?_odkw ... e&_sacat=0

haydent

bringing this back up again, anybody else ? (im using x8r too) been playing around with this a little more in gui, and i notice i only get travel from 1090 to 1909 yet without sbus i get 1000-2000 do others get the same ? wordering if this is deliberate, or possibly the signal not being translated ...

haydent

well done, sounds like you been busy, and it does sound like interference, if you get totally beat you could look into a external i2c compass module to give it some space, or maybe vertical shielding

haydent

i think some of the mobile apps had/have a remote control via 'serial' msp option

haydent

there is settings for gps in config.h such as com port and speed if this is what you mean ?

haydent

maybe you need to re/callibrate your mag sensor

haydent

well done, and glad you could do it yourself

haydent

dont forget to order the inverter too

haydent

sounds good to me

haydent

shameless bump, come on... someone has to be interested in this...

haydent

thank you very much or your detailed investigation and submission. I hope this can be integrated as promptly as possible.

edit, and i noticed you signed up just to post this, double thanks !!! and welcome

haydent

Hi all, just pointing out this mod for flyers and devs. Give it a fly ! I would also be interested in getting the MultiWii patch side of it integrated into Multiwii. That is the part that translates the S.Port serial data into Multiwii. A guide to setting it up is here: m Currently it supports Volts...

haydent

I just have the common 6m is faster at getting sats and gets more

haydent

get a ublox

haydent

individual cell monitoring is something its worth it for, as its important for your lipos health as cells dont drain equally

haydent

someone else was asking about this too. im not sure how close it currently is to doing this but its totally possible.

sounds like a good excuse for you to learn the basics of arduino and mwc ?
