I've been mucking around plans to produce a Teensy SDR shield of the most basic design. One stumbling block has been finding a clock source. I'm hoping to make use of the SPI clock as a carrier source but am really having a hard time figuring out if this is even practical. Is there anyone here familiar with this or where the documentation exists on how to use SPI port? Does it even provide a stable clock? Would I have to constantly cram null data into a buffer in order to keep the clock running?
