The KA04 sample code compilation on Uno with the VMA04 installed was unsuccessful and the first signs of this outcome
were the following linesin the printout
EtherCard.cpp: In static member function ‘static word Stash::cleanup()’:
EtherCard.cpp:267: warning: no return statement in function returning non-void
EtherCard.cpp:267: warning: control reaches end of non-void function
EtherCard.cpp: In static member function ‘static void Stash::extract(word, word, void*)’:
EtherCard.cpp:198: warning: ‘ptr’ may be used uninitialized in this function
The diode is blinking as the blinking led programme was installed first and I thought
that programming ought to be erased before but I could not find anything about this in
the documentation
