The original code also wrote the coord. I assume you simply missed to  
quote that.

No, that is OK. Because of the signature of some of the Read/Write  
methods you must make sure that read and write data types are  
matching. If you write it as uint32_t, you should read it with the  
same datatype :-) For enumeration values or similar the effective  
datatype are not always obvious so in that case you should explicitly  
cast.
