As we see, source code within the SPI.h and SPI.c has been commented in avr_local folder.
Also, it is not possible to simply copy+paste traditional SPI libraries for Arduino boards.(It will throw up with the compiler and syntax errors, especially undefined SPCR,SPSR,SPDR etc. ).
when can we expect a debug feature to be updated in plugin for codes that requires SPI or EEPROM libraries?
