Use SPI.beginTransaction() to play well with others #7

Closed frankleonrose closed 5 years ago

frankleonrose commented 6 years ago

This modification uses SPI.beginTransaction() in order to keep parameters consistent while sharing the hardware SPI bus with peripherals that use other parameters.

Specific changes

Call SPI.beginTransaction() before each chip select.
Use ClaimSPI helper class to avoid repeating conditional before and after each transaction.
