reverse Data

[HannHank]

Hello, this library is very great, but I have a problem. My Compass give me the reverse Data. It only worked for me when I turned the Compass on the other side, but there must be another way. I cant't use him in this position because the build in GPS need's it antenna pointed to the sky.

Thank's in advanced.

change compas_heading into this: `void compass_heading(){
compass_scalled_reading();

float heading = atan2(compass_x_scalled, compass_y_scalled);
// result need adjustment
if(heading > PI) {
heading -= PI;
}else {
heading = heading + PI;
}
bearing = heading * 180/M_PI;
}`
