The build part is almost complete. I need to make a couple more cables (s.bus, video, wire wrap some) then the scary part starts, the computer part....

Hi. I realize I promised this a month ago. My profound apologies. My job blew up on me, and I had to spend the last 3 weeks on the road. This week I managed to set up a googlecode project with download links and documentation for my alternative LEDring firmware. I am working on getting some demo videos uploaded as well. Hopefully this atones for my poor responsiveness.

https://code.google.com/p/ledring-kapu/

I'd appreciate feedback from anybody who can try it out. It works on my LEDring, but I'd like to hear from somebody else that it works on their's.

Happy Thanksgiving all!

I have a quick question, do I need to enable something in arduino for data to flow to my minimOSD?

I have the whitespy mega pro ez3 blacked board with the OSD on serial 3.

You do not. Works out of the box. Unless there's an option to disable it in the config (which I haven't seen?)

What are you running on your minimOSD?

Note: This ESC don't included manual.

Package:
1* 40A ESC
I am thinking about buying this motor also (XM3542MR-11.5) - what is your opinion about it?

Thanks,
tritan

I just unwrapped it and wired it up. Come to find out it has ArduCam 2.0 on it I think. Stays at waiting for MAVlink heartbeat.... forever. I figure it's different but also thought maybe it would read some data if data was flowing. .. like maybe get an error or something. Either way, gonna have to clear it and load rush at some point. Bigger issues atm. Tried changing the config to use s.bus and the new VTail mixes from Lynxmotion and lost the magnomitor and all the motors. Now Arduino won't upload any new sketches anymore.....

....not to mention I forgot about the usb and Bluetooth thing not being plugged in at the same time and now I can't get the Bluetooth to connect anymore.... not giving up but talk about discouraging.....

Any multiwii masters in the DFW area for hire? lol

I have been sifting through my earlier posts and can't find it... but how do you clear the board and start fresh? Clearing the eeprom or whatever.... I'm wondering after trying to upload a few times if I've corrupted something and that's why it hangs up when trying to upload now.... just sits there and never finishes....

Also, when in Arduino, under tools, and then board, which board is the board for the blacked mega 3 board? I selected "Arduino Mega 2560 or Mega ADK" but I don't even know if that's right, in the config.h file the board type says, "define FREEIMUv043 // same as FREEIMUv04 with final MPU6050 (with the right ACC scale)"

Orginially I was just going to leave it as is but I wanted to use s.bus, the newvtail.h file from lynxmotion and in looking at the multiwiiconfig, it lookd lik the magnometer wasn't working... then when the Bluetooth stopped connecting I figured how much worse could it get..... well.... anyway..... any help would be appreciated.

Thanks

ok, well, got my sketch to load. s.bus seems to be working.... I did this:

From Muddiman,
If you are using a Futaba Sbus connection to the flight controller, you need to change the channel sequence in the RX.ccp file. Changes needed are in bold print.

From:


Code:
#elif defined(SBUS) //Channel order for SBUS RX Configs
// for 16 + 2 Channels SBUS. The 10 extra channels 8->17 are not used by MultiWii, but it should be easy to integrate them.
static uint8_t rcChannel[RC_CHANS] = {PITCH,YAW,THROTTLE,ROLL,AUX1,AUX2,AUX3,AUX4,8,9,1 0,11,12,13,14,15,16,17};
To:


Code:
#elif defined(SBUS) //Channel order for SBUS RX Configs
// for 16 + 2 Channels SBUS. The 10 extra channels 8->17 are not used by MultiWii, but it should be easy to integrate them.
static uint8_t rcChannel[RC_CHANS] = {ROLL,PITCH,THROTTLE,YAW,AUX1,AUX2,AUX3,AUX4,8,9,1 0,11,12,13,14,15,16,17};

and now I'm wondering if I needed to.... I'm using frysky and not Futaba.... and changing this hosed up my sticks on the transmitter so I'm thinking of changing it back.

Of course the X8R is kinda big and you have those clunky PCB antennas to deal with.

You do need to uncomment a couple of lines to enable SBus in config.h of course, as well as your other configuration settings, and don't forget to edit the line in def.h if you have a black board with external mag.

Earlier 2.3 compilations had a timing problem with the FrSky SBus implementation (having been written for Futaba specs). If you are interested in the details (and want to be impressed by just how responsive the opensource community is), see this thread.

I don't know about other changes in the new 2.3 distro. I didn't even try the sketch that came pre-loaded or the one from the Witespy dropbox, because I found the thread above before I got my board and knew I wanted to run SBus. The first thing I did was flash with r1648, and it worked immediately. But I'd guess that the version Paul has is an earlier one. 1648 was only posted two weeks ago.
this talks about editing a line in def.h, what line? what's it supposed to be edited to? (I have the black board)

I'm confused, are you running MultiWii or MPNG?

If multiwii then you edit config.h

in config.h these lines
Code:
/*******************************    SBUS RECIVER    ************************************/
      /* The following line apply only for Futaba S-Bus Receiver on MEGA boards at RX1 only (Serial 1) or PROMICRO boards.
         You have to invert the S-Bus-Serial Signal e.g. with a Hex-Inverter like IC SN74 LS 04 */
      //#define SBUS
      //#define SBUS_SERIAL_PORT 1
      //#define SBUS_MID_OFFSET 988 //SBUS Mid-Point at 1500
I don't see any lines in config.h that need editing.

Also if you are using a OSD that was programmed for ArduPilot/MPNG and ARE running Multiwii then you need to flash it with firmware for MultiWii as the AP/MPNG firware is looking for MavLink data and MW doesn't support MavLink

I'm running MultiWii 2.3

I was a little overwhelmed and unsure so I was pretty much looking for anything that said s.bus and editing it. Either way now I'm backtracking and trying to see what really needed to be edited.

I did do what you mentioned, and the sbus seemed to be working but then I went to edit the end points in the multiconf. And it all froze up. It's late here and I'm tired so at that point I figured it was time to move to the sofa. lol
