To give you an idea of what I'm working with, here's my hardware list.
Teensy 2.0++ Configured using Teensyduino nRF24L01 Transceiver (http://www.sparkfun.com/commerce/product_info.php?products_id=691) nRF24L01 Fob (http://www.sparkfun.com/commerce/product_info.php?products_id=9377)
Presently I've got the teensy coded to do a number of small automation tasks that send keystrokes over the USB connection to the PC. This works great so far. My next task was going to be adding a wireless component to trigger these same automated tasks manually from remote.
The problem is that I can't get the code I found at(http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1245058973) to run on a Teensy. After noobing through a bit, I seem to gather it requires an SPI library for the Teensy 2.0++. I've searched for one, but my google-fu seems to be weak. I stole the spi.h file out of the ethernet example for the teensy, but that obviously doesn't work. I don't need someone to do all this for me, I just need a push in the right direction. If that direction is "It's way beyond the level you're at now," I am cool with that.
Oh, I should explain specifically what doesn't work on the Teensy. When I upload the sketch to the Teensy, it crashes in void setup() when setting the rxaddr. If I unplug the teensy and plug it back in, it will load up the last sketch.
