That’s a pain.

Just for completeness, in case this subject comes up again, according to this site, http://forum.arduino.cc/index.php?topic=132130.0 and http://arduino.cc/en/Reference/DueExtendedSPI the Due has three pins that could be used for chip select: D10 (same as D77), D4 (same as D87) or D52.


BTW, does¬†SPIClass::transfer()¬†really need to read back from SPI every time we write to the MP3 shield? I’m wondering why there are aren’t separate read() and write() methods instead and whether just writing would be faster when writing audio data.
