WMP bad?

I hate to ask total no0b questions but I have searched high and low and there is simply too much data to do a proper search. I think I may have a bad WMP.

With just the Arduino and WMP connected should I see gyro data when I move the board around? I uploaded the sketch, and see RX data in the GUI. I never see any gyro data.

Here's the board,

In the picture , You have two pins not yet to solder, They are scl & sda that connect to wmp !

It looks like he had no 5v connected to the wmp.

SDA / SCL are connected to A4 and A5.

Pro mini A4/A5 must be connect to shield board, Reference your picture the through hole seems no pin connected to shield board.

I have all pro mini edge pins connected. Where are a4 and a5?

never mind, I see it now.

A4/A5 are the holes over A3.

OK, so I have header pins connecting them now. When I run the gui with just the Arduino board and the WMP connected should I see changes when I move the motion plus around?

I hate to ask these stupid questions but I haven't found a quick start guide anywhere. It's funny, I make my living managing a team of engineers but I am having a hell of a time finding info since there is so much to search through.

OK, I tried the 1.9 sketch and gui and I see the data properly there. If I use Arduino 1.0 and the dev version of MultiWii I get no gyro data.

TheX,

Thanks for creating this post. I did the same thing and originally didn't connect the A4 and A5 to the breakout board.

just a guess, i'm wondering if you are getting i2c errors with the latest dev version. i can't remember when stricter i2c checking and debug2 counting were added. but if you run the latest dev version, which did not work, can you see if the debug2 counts (at the bottom of the screen) increase? if so, the s/w is reporting i2c access errors, which older versions of multiwii have previously ignored.
