GUI - no sensor output shown

[fietserse]

Hi there,

I'm new here, just started building a first triwiicopter and I can't wait to try it.

So far, I've connected the arduino (pro mini) with the WMP and NK. I uploaded a sketch (v2.1, with the right options checked in the config.h) and opened the GUI (v2.1, 32 bit) I hoped to see the sensor outputs, just for confirmation that my soldering is okay, but only got one straight line. Also, the picture on the right showed one ball with an arrow (like a monocopter), instead of a tricopter.

Is this because I didn't connect the receiver, ESC's, etc yet? Or did I make a mistake with soldering or maybe in the config.h?

Chances are that you have i2c errors, it wont work until you have got rid of those, they can be caused by multitude of things but usually bad/wrong connections, its easy to get the sda scl lines crossed. I would remove the nunchuck and just test it with the WMP, that way you eliminate a set of joints and a component. Can you put a screen shot up so we can see what we are looking at.

Okay, so I disconnected the NK. (and disabled it in the config.h file before uploading to the arduino again)

The GUI did show different results; the same straight sensor output lines but now also a (changing number) I2C error, and a correct but static picture of a tricopter at the right.

As far as I can see, I connected the wires in the right way. I had to extend the wires coming out of the connector at the bottom of the WMP, as you can see.

Or did I do anything else wrong? I'm no hero in debugging software, so I hope that won't be the problem?
