Radio/Receiver is messing up my sensor data!

[torxnl]

So I just started with multiwii and so far everything goes well. I try to connect the smaller parts first and move up from there. So first I connected my acc/gyro and that seems to work. Then I connected my receiver which does nothing of course until I turn on my transmitter. Well when I turn on my transmitter all of a sudden my acc and gyro start acting really weird and it looks to me that they are copying input values from the transmitter. Also when I turn on the transmitter the input values don't change in the gui.

How does this happen? I have changed the basics in the config but nothing more. I already read that it could be the i2c adress (which I did change to the right adress) but this is impossible because the receiver is connected through digital pins.

I am using a arduino leonardo and I have connected the sensor to SDA/SCL and my receiver to D2, D4, D5 and D6.

Below you can see a screenshot of what happened.

You are getting a huge number of I2C errors. Do these happen only after connecting receiver and turning the the TX?
In that case re-check the connections for the receiver.

receiver to D2, D4, D5 and D6.

This is not correct as far as I can tell. I think for a Atmega32U4they should be:
Thro -> D7
AILE (roll) -> MOSI, D16
Elev (pitch) -> MISO, D14
rudd (Yaw) -> SCK, D15
AUX1 -> D8
AUX2 -> D17

Some other info I found:

- If you are going to use a regular RX, DO NOT uncomment #define A32U4ALLPINS. That will mess up the RX pin order on the board.

- You will need to uncomment #define RCAUX2PIND17 if you plan on using Aux2, which will probably be needed in most cases if you want to activate / deactivate BARO, for example.

You are right indeed, by connecting the receiver to the right inputs I no longer got any i2c errors. So that's solved. But now when I connect my ESC's, the same thing happens again. I connected them to D2, D5, D6 and D3. I guess that must be wrong too then?

Do you know perhaps where I can find more info on using multiwii on a leonardo? So far I have gotten most of my information from here http://www.multiwii.com/connecting-elements but I don't think all of it can be applied to my board.

Ok, the correct pins works better. Again wrong pins for the ESCs. The diagrams in the link is for the Atmega 328 and a 'mega' not the 32U4 processor which has a very different pinout.
I used connection info from Witespy's Flip Pro FC board. It uses the Atmega32U4 so the pin outs are the same as the leonardo since it is a leonardo plus sensors and connectors.
Follow the ESC connections and motor rotations here:

Also google search for "multiwi arduino leonardo" for some additional info.

Thanks for the help! This should do it now. I have already googled around a bit but I don't exactly know what to look for.

Look for any FC boards that use an Atmega32U4 processor and MultiWii code.
Then look at what pins they use.
