* Hardware SPI and a software SPI implementations are included in this file.
* The hardware SPI runs faster and has higher throughput but is not compatible
* with some LCD interfaces/adapters.
*
* Control of the slave select pin(s) is handled by the calling routines.
*
* Some of the LCD interfaces/adapters result in the LCD SPI and the SD card
* SPI sharing pins. The SCK, MOSI & MISO pins can NOT be set/cleared with
* WRITE nor digitalWrite when the hardware SPI module within the LPC17xx is
* active. If any of these pins are shared then the software SPI must be used.
*
* A more sophisticated hardware SPI can be found at the following link. This
* implementation has not been fully debugged.
