+The code underneath this commentbox has some fixed parameters for serial/ADC reading:
+-> The address for the angle_device_reference_belt is set to 0x68 in the file MPU6050_belt (rule number: 19);
+-> The adress for the angle_device_sensorplate is set to 0x69 in the file MPU6050.h (rule number: 19);
+-> This is because of using the same I2C line;
+-> For detailed information/questions about this item, please read the technical manual or contact: Ricardo Molenaar | ricardo.molenaar@gmail.com
