Hello,
I have the same problème than Rudyv
I follow what you said Cmaglie and numbers of errors has decreased !
But I still have errors 
:
LPD8806.cpp: In member function 'void LPD8806::updatePins(uint32_t, uint32_t)':
LPD8806.cpp:58: error: cannot convert 'volatile RwReg*' to 'volatile uint8_t*' in assignment
LPD8806.cpp:60: error: cannot convert 'volatile RwReg*' to 'volatile uint8_t*' in assignment
LPD8806.cpp: In member function 'void LPD8806::startSPI()':
LPD8806.cpp:85: error: 'SPDR' was not declared in this scope
LPD8806.cpp: In member function 'void LPD8806::show()':
LPD8806.cpp:125: error: 'SPSR' was not declared in this scope
LPD8806.cpp:125: error: 'SPIF' was not declared in this scope
LPD8806.cpp:126: error: 'SPDR' was not declared in this scope
Have you other ideas in order to solve that ?
Thank you for all
