Teensy 3.0 as SPI Slave

[ariesboy571]

I have. It works. I have updated the library some, and I've learned some new tricks with it. Let me know if you need any assistance.

I have been looking for something that allows a slave's data to be read by the master, but I'm doing this on a Teensy 3.6. Are you still working with your library? Does it still work?

I've downloaded the library, but the examples won't compile. I'm compiling for Teensy 3.6, but I changed to Teensy 3.0, then 3.1/3.2; the compile errors are line-for-line identical:
