New SdFat optimized for Mega and Teensy 3.0

  1. Great work on the awesome library!

  2. I may be out to lunch here, but I have a pickle of a problem driving me nuts with SPI;
    --If I understand correctly, the Teensy 3.0 has multiple SPI ports. (yay/nay?) They are numbered on the pinout sheet but there isn't a lot of data available yet -- and the proper datasheet is WAY above my understanding. (appreciate the patience with my noobtacular questions)
    --Can the SDFat library be pointed to the secondary spi port (1 or 2 instead of 0)?

Long story short I'm interfacing an SD card and a non-standard spi device (addressable led strand that accepts clock/data) with FastSPI library. It worked on arduino but I needed more speed, so I moved to Teensy. I fake chip/slave select with a transistor interrupting the clock line while the sd reads - so far so good. -- the new library reads the files exceptionally well (an order of magnitude faster!) but when I go to use the spi port while I'm not reading/writing anything, I still get garbled data out. I was hoping to move one of the competing libraries to a separate spi port, or (gasp) bitbang it. :frowning: I don't think I can maintain the immense datarate of hardware spi bitbanging it.

Thanks in advance and again great work!
