Notation error

Posted by: @quince

Hello all, I am having trouble with a hardware change from a H5883 to a 9 axis Arduino motion shield.There is a notation error in the code, but I have looked so long it could be bracketed in neon I don't know if I would see it. Any help is appreciated. Thanks, Quince

Hi @quince, Look at line

Posted by: @quince

float ypr[3];// [yaw, pitch, roll] yaw/pitch/roll containerint heading= mySensor.readEulerHeading

Is the part containerint heading= mySensor.readEulerHeading suppose to be commented?

Just for S&G, I pasted your code into the compiler.  But I don't have the libraries your code needs and I don't want to download them just to help out with an error that you could easily just copy and paste into a post.  You might actually get an answer that way.

Another suggestion would be to use proper indentions for every sub section and line up the matching curly braces in the same columns.  That is an old professional coder's best advice - NEATNESS COUNTS! 

Another option - If you place the cursor of the Arduino editor on a curly brace it will "box" the matching mate.  If you put the cursor on the opening curly brace after your loop method (line 44), you'll see the mate is on line 82!  All code after that is flapping in the wind and not part of any function.

@inst-tech @quince I see the following errors (start corrections at highest line #'s so as to not modify following line #'s

Line 118 s/b }

Line 99 if (ypr[0], <= 180) remove the ,

Line 96 appears to be simply extra. Remove it

Lines 92 and 93, one is extra and 93 is missing )

Line 83 if (ypr[0] - compassCorrection) >= 0); is missing ( after if and has extra ; at end

           if ((ypr[0] - compassCorrection) >= 0)   //  <<< correct

Line 82 is the end of the sketch. Remove that line?

Besides line 18 being suspicious, the #define at 41 relates to it and is a one of. The lines 38, 39, and 40 make no sense.

@zander 

Ron, been working on changing and combining code. Blind at this point. I will give your suggestions a try and cross my fingers. Thanks, Quince

@quince See my complete post at Here I made all those changes and it does compile. I did nothing re 18 and 38 to 41 as they compile clean but are suspicious looking.

I am sorry for not posting the error message. Quince

@zander Ron, Did you post the code with changes made? I see the changes when I press here and am still working on it. If you have the code compiled Please send it. Thanks, Quince 

@quince Ok, here is the modified code except for 18 and 38 to 41, I don't know what you were doing there, it compiles clean but is suspicious. I have attached a zip file of the clean code.

@quince Notice how the compiler gave you a HINT about modifying your preferences to get better compiler diagnostics! ALWAYS obey the compiler gods! This is what you posted above under 'I am sorry for not posting the error message.'

@quince Note the following from arduino. I personally never use #define.

Here is the arduino ref pg Arduino Reference manual page
