    Telling us simply "it does not work" is not enough to give efficient help. The forum rule requires that you publish all needed information like code, schematics, and so on, so that others might precisely reproduce your problem.

    What does not work? Is it the data flow on the MOSI pin? the assertion of the CS or Reset pins? Or is it missing specific defines for the Teensy in the library's source code? What have you already done to find the cause of the problem?
