crius se v2.5 12c errors annoying!!!

[quadcrazy]

when I hooked this board up for the first time I had sensor movement on the graph and response to pitch roll but not yaw when I moved the board . now. nothing!! quad x is on the screen in multiwii 2.1 but no movement in the graph or pitch roll and yaw. 12c error is just running numbers. I have the board in tools in arduino set at duemilanove atmega 328. I am ready to give up!! never had these problems before with a standard crius se board. any help would be much appreciated, otherwise I will assume this board is bad?

You selected wrong board which is why sensors are not functioning correctly. My first build used the Crius SE V2.5 & I used #define CRIUS_SE_v2_0 // Crius MultiWii SE 2.0 with MPU6050, HMC5883 and BMP085. The only problem with this board as well as many others is that the Mag IC (HMC5883) is onboard & can be affected by magnetic fields from distribution board & wiring to ESCs. Unfortunately there is no easy way to disable the Mag on these boards & use an Ext Mag. You needto go to Crius AIOP V2 to get this feature plus loads more for very little extra money.

In Arduino, set the board to pro mini.
Check in the config.h if you chose the correct board.
If the board is right and you keep getting i2c errors, chances are that you have a defective board.

ok here goes, there is no crius se 2.0 with mpu6050 hmc5883 bmp085 in my list in arduino only crius lite or crius se so I kept it in crius se and assume you mean to uncomment those numbers in the independent sensors? I did that and changed the board under tools as per arakons reply to pro or pro mini with atmega 328 5volt , uploaded this and got an instant error saying redefinition of void gyro _initO honestly I need a full rundown on the correct settings

You can't define the board and then seperate sensors on top of that.
Why are you using Multiwii 2.1? In 2.3, I get:
//#define CRIUS_LITE // Crius MultiWii Lite
//#define CRIUS_SE // Crius MultiWii SE
//#define CRIUS_SE_v2_0 // Crius MultiWii SE 2.0 with MPU6050, HMC5883 and BMP085

You can try #define HK_MultiWii_SE_V2 if you have that.
Failing that, don't comment any board and set the sensors in the independant sensor list.
