how could i create a functioning check on a sensor, i want to confirm it is working in the code, say with a boolean? I want to create an error or a success message on boot up.
I tried writing this with compass.init() but it does not run.
here is a code snippet from my program, also im running this via multiplexor system.
//////////////////////////////////////////////////////////////////////////// COMPASS ACTIVATE
tcaSelect(bus2); // enable I2C channel 2
Wire.beginTransmission(addr2);
if(compass.init()){
Serial.println("compass Init failed!");
}
else{
compass.setCalibration(-428, 656, -2357, 0, 0, 980);
Serial.println("Compass init Success & Calibrated");
}
Wire.endTransmission();
error message
exit status 1
Compilation error: could not convert 'compass.QMC5883LCompass::init()' from 'void' to 'bool'
and here is a standard example of the compass
