It is this

error: Spi.h: No such file or directory

The SPI library is supposed to be included now but someone else was having trouble with it the other day. Try putting it in your libraries folder.

i have already put it in the library folder and still get the compile errors.

You have SPI.h or Spi.h? They are not the same file, and they represent different classes and libraries, and are not directly substitutable.

5

where can i download the Spi.h files from ?

You'd be better off upgrading that code to use SPI.h.
