Function generator code modified to work on the Freescale KL25Z
Fork of
AD9850 function generator SPI driver

This is an update to the original AD9850 SPI driver produced by Liam Goudge.
The main changes are to assign the appropriate pins and to send the 40-bit AD9850 programming word as five 8-bit packets. This is necessary because the KL25Z only supports 8-bit SPI transfers.
