    teency 3.2 and internal clock and backup battery

    for most clocks I build I ha have used "SparkFun DeadOn RTC Breakout - DS3234". I would like to use the Teency with a 3.2 crystal and a backup battery button.
    are there instructions and a SW lib for that?

    Sparkfun's library looks like it should work on any Teensy board, since it just uses the ordinary SPI library and Arduino functions.
