Hi Everyone,Im trying and strugling to write some custom code for my gimbal mount. If you can write code and need some parts cutting for your multirotor (or anything) maybe we can do a deal.Basically I am trying to get the gimbal neutral and retract function on my multirotor to be activated by a switch on my transmitter. It seems like the code is only for arduplane and is only enabled by a mavlink message.My cnc machine is only a desk top one (roland mdx20) that is capable of cutting 210mm x…See More

"KevinB,     Yes, I think that's all that's required.  Move the ppm encoder's handlign of channel 3 to 1."

Kevin B replied to alex corbett's discussion FRSKY PPM SETUP HELP REQUIRED PLEASE.
"Randy, to me it looks like PPM_Encoder.h by default sends all servos centered, and servo3 gets 900us during a failsafe, which with PPM passthrough would presumably include unplugging and 32u2 failures only. I looked at the code to see if explicitly…"

"So to be clear, for Spektrum/JR/FRSky PPM... We short pins 2-3, connect PPM to pin5 (not pin1 as in wiki), change the 3 lines in radio.pde, and it will work? In this configuration, ch1 <900uS or flatline will failsafe, and the 32u2 does…"

Hi Alex,

I did get my tricopter flying on the APM1. It wasn't nearly as good as the KK board though. Aero mode wasn't worth trying, but stabilize was manageable. I had to turn all the D terms to zero. Others were rate_p 0.118 stab_p 5.5 and stab_yawP 7.6 - this is on an RCExplorer tricopter.

The tri was jerking a lot though, every 2 or 3 seconds I think... putting on a five degree roll or pitch and back again. Also the yaw felt sloppy.

I managed to break my GPS and needed my APM for the T3 contest on fixed wing, so I've put the tri down for now. I think it needs a lot of work

Please let me know if you have any better luck!!

Colin
