 /* Error Codes:
- * In Arduino if a function returns 1 is considered to have run successfully,
- * any value different from 1 is considered an error.
+ * In Arduino if a function returns 0 is considered to have failed,
+ * while any value different from 0 is considered success.
  * Errors are generally represented with an int type that may vary in size depending on the platform.
  * For this reason in this representation error_t type is defined with an integer type with a defined size.
