SPI slave mode

[ghost]

Hello,

I am looking for a way to set the Teensy SPI bus as slave, I saw this:
https://github.com/btmcmahan/Teensy-3.0-SPI-Master---Slave

Do you think is possible to add to your code the slave mode?
Thank you

Sorry for the super late reply...
1: I may toy with this idea this summer.
2: The original drive behind this library was to just run mode0 as quickly as possible and to only TX or only RX, and not do both at the same time.
