Crius v2.5 Multiwii Flight Controller Board

With this Crius v2.5 board there is little no no documentation on what settings to load sketches and a predefined board type. When looking at the Multiwii Boards from HobbyKing I noticed that they had a board with the same sensors as the Crius v2.5 board.

Mine came loaded with Multiwii v 2.2 but I was having issues connecting and loading the PID and other settings over Bluetooth. It turned out that was due to the baud rate being incorrect, but it forced me to dig into what sketch settings to use.

I was using the Android Multiwii Configurator App from the Android Market but it currently does not support Multiwii 2.2.

To flash the board you want to use the Arduino Duemilanove / ATmega328 when writing your sketch to your board.

I wanted to see if I could take the HK_MultiWii_SE_V2 settings and define the board with MultiWii  2.1 , in the conf.h I copy and pasted the new definition in the 2.1

In the 2.1 IMU Orientations and Sensor definitions I scrolled to the bottom to the last #endif and added the following code:

#if defined(HK_MultiWii_SE_V2 )<br />   #define MPU6050<br />   #define HMC5883<br />   #define BMP085<br />   #define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL]  = -X; accADC[PITCH]  = -Y; accADC[YAW]  =  Z;}<br />   #define GYRO_ORIENTATION(X, Y, Z){gyroADC[ROLL] =  Y; gyroADC[PITCH] = -X; gyroADC[YAW] = -Z;}<br />   #define MAG_ORIENTATION(X, Y, Z) {magADC[ROLL]  =  X; magADC[PITCH]  =  Y; magADC[YAW]  = -Z;}<br />   #define MPU6050_EN_I2C_BYPASS // MAG connected to the AUX I2C bus of MPU6050<br />   #undef INTERNAL_I2C_PULLUPS<br /> #endif

I flashed the board and checked the sensors in MultiWin Gui and everything was working great. I haven't tried to fly this configuration quite yet but I will a bit later today.

So far this boards configuration is the same as the MultiWii Se v2.0 Flight Controller from Hobbyking. The sensors and everything are the same except that the I2C has 8 pins on the Crius board.
