I assume one only needs 5V, GND, Tx and Rx?
Hm, hard to say, smoetimes it can be misunderstood cause a rx have always go to a tx, maybe they only changed the naming.
The printing for serial connectons is sometimes misleading.
It have to be tested, i dont think they changed it, there is no reason to change the standard.
As a reference.
This is how I connected the Basic Sparkfun FTDI board to the Flyduino. It works fine for me.

- In the current / default MultiWii code, do the 6 motor outputs needed for a Hex appear on 'PWM Out' pins 2, 3, 4, 5, 6, and 7?
Its 2,3,5,6,7,8

The Flyduino Diagram is not up to date.
True, & updated. I also added Warthox his ppm layout as a reference. (link)
Should be something like below
I'm still not sure about the LLC, it doesn't heart but I don't think anyone uses the LLC with the FFIMU. So maybe it's better to remove it from the diagram.

Can't wait to get this all up and running!

Hi David,

I think you have the RX connections wrong. They should be shifted one up I believe?

I have wired my flyduino with ffimu all sensors in gui was ok then add esc and motors and all was ok but neeeded pid adjustement so after doing that I disconnect ftdi and shut domn batterie and when Itried to start again in the kitchen motors don't arm!
return to pc and in the gui sensors are all flat(yes red and green lights on) and when I move tx in the gui throttle and others move very slowly baud rate 115 200 as before,adjust throttle min to 980 to be sure and no more arming!
Tryed to another seven ultimate 64 and got the same thing in the gui.
Help help please!

Claude

green light flyduino on and other near ftdi without it connected is flashing

Thanks for the heads up guys I did actually amend that image but I obviously uploaded the wrong one!

Do you have any pre-built boards left? If not can you put me on the list for one.

There are boards left in the shop www.flyduino.com
Got the BOBīs today, will solder some later this evening and ad them to the shop.

@Claude
Its hard to say but it really sound like a bad connection or wiring.
Flyduino seems to work fine, power led is on and flashing "ftdi" Led means the code is running.
He reacts like if he didnt have any senors connected.
Please check connection to the sensors twice.

I am not using the connectors that came with the power board, just soldered my ESCs to the board to keep it all low profile. My sensor BOB will be sitting less than 10mm above this. Obviously being careful that nothing between the 2 boards touches.
Quoting myself, don't want this question to be lost.

hi,
thanks for the download link for the developer code

the octo is coded as if there were 2 quads over each other , so as a x8 ( like the y6 )

i changed it so there are no motors over each others :
Quote:
#ifdef OCTO-flat-8
motor[0] = rcCommand[THROTTLE] + axisPID[ROLL]/2 - axisPID[PITCH] - YAW_DIRECTION * axisPID[YAW]; //left-front
motor[1] = rcCommand[THROTTLE] + axisPID[ROLL] - axisPID[PITCH]/2 + YAW_DIRECTION * axisPID[YAW]; //FRONT_L
motor[2] = rcCommand[THROTTLE] - axisPID[ROLL] - axisPID[PITCH]/2 - YAW_DIRECTION * axisPID[YAW]; //FRONT_R
motor[3] = rcCommand[THROTTLE] - axisPID[ROLL]/2 - axisPID[PITCH] + YAW_DIRECTION * axisPID[YAW]; //right-front
motor[4] = rcCommand[THROTTLE] - axisPID[ROLL]/2 + axisPID[PITCH] - YAW_DIRECTION * axisPID[YAW]; //right-rear
motor[5] = rcCommand[THROTTLE] - axisPID[ROLL] + axisPID[PITCH]/2 + YAW_DIRECTION * axisPID[YAW]; //REAR_R
motor[6] = rcCommand[THROTTLE] + axisPID[ROLL] + axisPID[PITCH]/2 - YAW_DIRECTION * axisPID[YAW]; //REAR_L
motor[7] = rcCommand[THROTTLE] + axisPID[ROLL]/2 + axisPID[PITCH] + YAW_DIRECTION * axisPID[YAW]; //left-rear
#endif
would someone please put this in the code ? alex ?

Hi M4d_D,

Thanks for your work, I'm really interested by your octo code!

Just a question:
The motors definition at the end of the code lines don't really help to figure out where is which motor...

Quote:
#ifdef OCTO-flat-8
motor[0] = rcCommand[THROTTLE] + axisPID[ROLL]/2 - axisPID[PITCH] - YAW_DIRECTION * axisPID[YAW]; //left-front
motor[1] = rcCommand[THROTTLE] + axisPID[ROLL] - axisPID[PITCH]/2 + YAW_DIRECTION * axisPID[YAW]; //FRONT_L
motor[2] = rcCommand[THROTTLE] - axisPID[ROLL] - axisPID[PITCH]/2 - YAW_DIRECTION * axisPID[YAW]; //FRONT_R
motor[3] = rcCommand[THROTTLE] - axisPID[ROLL]/2 - axisPID[PITCH] + YAW_DIRECTION * axisPID[YAW]; //right-front
motor[4] = rcCommand[THROTTLE] - axisPID[ROLL]/2 + axisPID[PITCH] - YAW_DIRECTION * axisPID[YAW]; //right-rear
motor[5] = rcCommand[THROTTLE] - axisPID[ROLL] + axisPID[PITCH]/2 + YAW_DIRECTION * axisPID[YAW]; //REAR_R
motor[6] = rcCommand[THROTTLE] + axisPID[ROLL] + axisPID[PITCH]/2 - YAW_DIRECTION * axisPID[YAW]; //REAR_L
motor[7] = rcCommand[THROTTLE] + axisPID[ROLL]/2 + axisPID[PITCH] + YAW_DIRECTION * axisPID[YAW]; //left-rear
#endif
Could you change them to more "n00b-friendly" definitions, or draw a wiring diagram?

Thanks a lot!

Bastien

Wrong thread guys!
You should ask the coder. Looks like this Octo is set up in X mode.
So looking from the top clockwise front left is the one after left front and right back sits before back right, capiche?

A plus (+) setup with 1 arm pointing to the front would be much clearer...
