There are a few simple rules for using that library. Please read the following summary and apply it to your project
Required header files (#include ...) and Setup side code.
#include <Wire.h>
#include <MechaQMC5883.h>
void setup(){
Wire.begin();
}The object declaration method. It is used outside the setup statement, and a name such as qmc can be changed to any other name you want.
#include <Wire.h>
#include <MechaQMC5883.h>
MechaQMC5883 qmc;QMC5883 Sensor's setting function.
The init function allows you to take advantage of the features of the QMC5883 sensor by default.
void setup(){
Wire.begin();
qmc.init();
}If you want more detailed settings, you can use it as follows.
void setup(){
Wire.begin();
qmc.init();
qmc.setMode(Mode_Standby,ODR_200Hz,RNG_8G,OSR_512);
}The values used for setMode can take the following values:
Mode : Mode_Standby / Mode_Continuous
ODR : ODR_10Hz / ODR_50Hz / ODR_100Hz / ODR_200Hz
ouput data update rate
RNG : RNG_2G / RNG_8G
magneticfield measurement range
OSR : OSR_512 / OSR_256 / OSR_128 / OSR_64
over sampling rate
How to read the measured sensor value is as follows.
void loop(){
int x,y,z;
qmc.read(&x,&y,&z);
}and we can get azimuth too.
void loop(){
int x,y,z;
int a;
//float a; //can get float value
qmc.read(&x,&y,&z,&a);
}also can claculate azimuth you want
void loop(){
int x,y,z;
int a;
qmc.read(&x,&y,&z);
a = qmc.azimuth(&y,&x);
}It can be seen as a collection of the contents mentioned above.
#include <Wire.h>
#include <MechaQMC5883.h>
MechaQMC5883 qmc;
void setup() {
Wire.begin();
Serial.begin(9600);
qmc.init();
//qmc.setMode(Mode_Continuous,ODR_200Hz,RNG_2G,OSR_256);
}
void loop() {
int x,y,z;
qmc.read(&x,&y,&z);
Serial.print("x: ");
Serial.print(x);
Serial.print(" y: ");
Serial.print(y);
Serial.print(" z: ");
Serial.print(z);
Serial.println();
delay(100);
