Error Compiling with USE_MAGNETOMETER == 1 #11

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Setting USE_MAGNETOMETER == 1 

What version of the product are you using? On what operating system?
IMU v2+; Windows 7

Please provide any additional information below.

#if USE_MAGNETOMETER == 1
    APM_Compass.Init(); // I2C initialization
    debug_handler(3);
#endif

arduimu.cpp: In function 'void setup()':
arduimu:286: error: 'APM_Compass' was not declared in this scope
arduimu.cpp: In function 'void loop()':
arduimu:385: error: 'APM_Compass' was not declared in this scope
arduimu.cpp: In function 'void Drift_correction()':
DCM:170: error: 'AP_Compass' was not declared in this scope

also, how does one define which orientation matrix to use? is it here?

virtual void set_orientation(const Matrix3f &rotation_matrix);

try to insert as global variable
APM_Compass_Class APM_Compass;

I added APM_Compass as a global variable but there were other problems - in 
some places AP_Compass versus APM_Compass, etc... I'll see if I can debug 
those, but in the meantime I turned off magnetometer.

You need to change all AP_Compass into APM_Compass and if you don't use the 
binary output, change also 
    #if USE_MAGNETOMETER == 1
        Serial.print("MGX:");
        Serial.print(APM_Compass.Mag_X);
        Serial.print (",MGY:");
        Serial.print(APM_Compass.Mag_Y);
        Serial.print (",MGZ:");
        Serial.print(APM_Compass.Mag_Z);
        Serial.print (",MGH:");
        Serial.print(APM_Compass.Heading);
        Serial.print (",");
    #endif

There is one spot where you have to change from a global variable Mag_HeadingX 
or something like that to calling the APM_Compass.Heading_X.

Separate from that, lines to initialize the compass offset, declination and 
orientation on airframe need to be added.  The airframe one is confusing - 
reading the APM_Compass.h file and looking at the markings on the boards say 
that a RH coordinate system is not in use and that components up, pins right 
should be a 45 yaw rotation (which the markings say it's just -yaw????)

The attached patch fixed compiling the ArduIMU 1.8.2 code with the Magnetometer 
for me. It would be nice if it could be included in the code base. Thanks!

I have spent a lot of time trying to fix this problem i have finally fix it i 
will attach the patch file. This worked for me so pleases cheek it out let me 
know.

Note: You will need to update the IMU Library's to the latest revision and put 
the files APM_Compass.h and APM_Compass.cpp in your 
(Documents\Arduino\libraries\AP_Compass) folder

I've noticed that if I have 
#define USE_MAGNETOMETER 0
and
#define PRINT_MAGNETOMETER 1
then I get a similar problem. 
I'm using ArduIMU 1.9.8
Solution: make both "1" or "0"
