Use SPI1 with MOSI only?

Hi all,

I’m wondering if it’s possible to use SPI1 with only the MOSI line active. I’m working on a bit of troubleshooting, and would like to be able to use D4 on the Boron for another purpose. So far it seems rather grumpy about that.


@psherk, mapping the SPI function maps all pins (MISO, MOSI, SCK) so you can’t reallocate one of those while SPI1 is active.
