Exception 9: LoadStoreAlignmentCause: Load or store to an unaligned address

[balucio]

Hi, I'm trying to use this useful library with "Dynamic Params". I defined the struct as reported at end, but when I try to Serial print the value value of SENSOR_TYPE (Serial.print("TIPO SENSORE ");Serial.println(SENSOR_TYPE);) I get the exception as in subject.
Can you help me?
Thank you.
